RooBee One Open Source DLP SLA 3D Printer

Aldric Negrier developed this DLP projector based open sourced 3d printer. It looks easy to assemble and cheap to make. It all depends on how cheap can you find a suitable projector. 

Project description:
Roobee One is an SLA DLP 3D printer inspired on the Cristelia - SLA/LCD 3d printer and the Vulcanus MAX 3D printer.
It is built out of 20x20 mm aluminum profile chassis, It has an adustable print area of 80x60x200 mm up to 150x105x200mm build volume using a ACER DLP projector.
The open-source machine is called RooBee One because it is red color just like a Ruby gem.

ONO Smartphone Illumination DLP 3D Printer

ONO is a novel approach to 3d printing and it uses your smartphone as a light source for curing of daylight resin. It should cost just 99$.
DLP 3d printers that use visible light from an LCD panels are getting more developed and should lower the price.


Here is Adafruit Industries talking with ONO crew about their machine:

PS: I'm not sure how do they expect that millennials give up their phones for the time needed to print something...



LiteFab Open Source DLP 3D Printer

LiteFab is an rugged open source DLP 3D printer you can build yourself at a low cost and which comes with an excellent step-by-stem construction guide.
The cost for this project is some 400-500 USD plus the DLP projector which you can buy new or used which will cost you some 50 - 1000 USD extra. For this build the developer used Acer h6510bd.

The supporting structure is made from CNC cut wood, aluminum rails and 3d printed parts. It looks very hackable, which is encouraged by the developer.

This machines is developed by Instructables user that goes by name of bongoboy23. Cool name bro! Thnx for this project!

Some of the features of this design:
  • Quick removable vat
  • FlexVat design means no secondary action needed for peeling parts off vat. For example, the Form1 pulls the vat down on one side to peel parts off the vat. The FEP film used in a flexvat, being flexible, peels as it flexes. This film also has a much longer lifetime then standard vats, which means less often replacement of the vat.
  • Quick removable bed
  • Adaptable for use with any projector 
  • Large vat allows for a large build area
  • Nice open area for easy access to components, for easier maintenance and modification
  • Opensource! All the design files are provided.

SprintRay MoonRay High Resolution UV DLP 3D Printer

SprintRay presented their MoonRay high resolution UV DLP 3D printer. It will be priced at  3499 USD.















Key features:

  • Custom-built projector for 3D printing fine details: MoonRay’s resin requires UV light for proper curing. Other similar 3D printers use commercial projectors, which produce visible light but not pure UV light. The advantages of the custom UV LED projector in MoonRay are in the resolution and curing process. The MoonRay’s UV projector, RayOne, was custom designed with some special qualities:
  • Perfect light spectrum: The resin used for 3D printing cures under light with a 405nm wavelength. The custom-built projector hits the proper wavelength consistently across the build platform, which allows you to get real 100-micron resolution.
  • Runs cool and quiet: Utilizing a UV projector allows the MoonRay to avoid any overheating and makes it much quieter than other 3D printers.
  • Long lifespan: RayOne’s 50,000-hour lifespan means you won’t ever need to replace the bulb.
  • Revolutionary resin tank: the team designed the MoonRay’s resin tank to last, so there’s no more replacing your printer’s resin tank or changing the PDMS layer

Chimera DLP 3D Printer You Can Build for Under 60$

Here is one of the cheapest DIY 3d printers you can make, with cost at around 60 USD, and it is DLP SLA machine!
It also comes with very detailed construction guide made by the developer "matstermind".

How can the price be so low? Mostly by using used or scraped parts. You can see it in the parts list below.

Bill of materials:
  • 1x Mitsubishi XD221u 1024x768 video projector, used or second-hand $50
  • 1x computer disc drive laser deck assembly (must be one with a stepper motor), free from scrap disc drive
  • 1x Arduino UNO / Duemilanove or atmega328 based Arduino clone, $4 ebay, used or second-hand
  • 1x Easydriver v4.4, $2 from ebay
  • misc wire, solder, etc.
  • (optional) Ability to etch circuit boards (you can protoboard/breadboard it if you have to)
  • (possibly) 5v, .5A power supply. Some laser decks can be powered by the USB port by the Arduino, some may need a power supply to be plugged into the Arduino or M+ on the easydriver to make the motor move. It will depend on the power of your USB port. My deck did not need one.
  • Total=$55.5
  • (optional for frame) scrap wood for free or 2x4ft MDF board or $10 from hardware store

Looks rough and simple with wood frame. I like the style ...

Chimera is named inspired by mythological creature that is made up of three different animals since this printer is made by using the recycled/modified parts of three different categories (projector, toys, and old computer stuff), hence the name.

Hack your FDM Delta into DLP 3D printer

As I was researching low cost DLP solutions I found this project by sirocco where he converted his old Delta into DLP SLA 3d printer by putting a projector on the top opening and adding vat resin. Delta configuration looks like good option due to hight.

I'm not sure how he moves his vat with salt water and resin, it could be done by separate mechanism or by some type of vat tray mounted on three points to the Delta frame and moved by existing motors.

How to build the cheapest DLP SLA 3d printer for under 500$ including projector

This is probably the cheapest DLP SLA 3D printer that you can build yourself for some 500 USD including the projector!

"Little Dipper" has a simple design that anyone can replicate with some basic DIY skills and it makes prints with reasonable quality.
The most expenisve par is the projector which you can get dfor some 350 USd new, but you could probably get it used somewhere. Other parts include simple z axis movement (screw or belt driven) on wood frame and Ramps 1.4 or Arduino controlled electronics.

Simple plastic vat and z axis screw drive

Objects 3d printed on Little Dipper


Little Dipper DIY DLP Sla 3d printer. You can see all the elements with DLP projector on top.

Here is the project description from the makers:

How it works?
A DLP projector is used to cure UV setting resin one layer at a time while a moving axis drops incrementally into the vat of resin. A projected slice cures each layer and builds the part. This style of resin printer is different from a FormLabs 3D printer and some others in two ways.
  1. It uses a DLP projector rather than a laser to cure each layer.
  2. It shines the light source from the top rather than up from the bottom.
Advantages over laser based bottom up and DLP bottom up designs:
  • Simplicity
  • Lower start-up cost
  • Modifiable to bottom up
  • Fast build (~1 evening)
Major Components and Materials:

DLP projector
There are 2 known choices, although others may work.
  1. Acer P1283 DLP Projector
  2. Acer H6510BD DLP HD projector
Linear Slide/Axis

Almost any linear axis that is belt driven or screw driven will work. Project uses a minimal version of this:
http://www.openbuilds.com/builds/v-slot-lead-screw...
A more budget minded and adventurous person could even choose a drawer slide, but you may find that rigidity and smooth sliding in the z-axis will be a useful feature.

4x4 sheet of 1/2in MDF or equivalent material and hardware

The version shown here is as simple as it gets. 2 pices of MDF cut to provide a mount for the axis, projector and stable footing for the machine. Pretty much any kind of enclosure can be designed for this 3D printer. Your main objective is frame rigidity and ambient light blocking.

Ramps 1.4 or Arduino based electronics capable of running at least (1) nema 17 stepper motor
This build features a RAMPS 1.4 board, stepper drivers and an Arduino Mega 2650 with standard Sprinter firmware. There are some basic modifications needed depending on the hardware you choose. None of these modifications constitute needing to know anything in-depth about programming. The firmware used is modified for 5/16 standard threaded rod and has end-stops disabled. You can modify this firmware using the Arduino environment to further suit your needs.

UV Resin

Makerjuice.com, Madesolid.com are the two most seemingly popular and affordable options for UV resin suitable for DIY resin printers such as the one featured in this build. This build has been tested with G+ from Makerjuice. Funtodoo, Form1+ and Spark/Ember resin formulations are likely suitable.

Build Platform and Plastic Tupperware vat

This build includes plans for a build platform that fits a specific set of Tupperware available at "wallyworld". The benefit to the type chosen in this build is that you get a variety of sizes that scale easily, so that extensive design modifications are not needed. You will also need additional containers for post-cure/clean up of your resin parts.

Control Software and Slicer

Creation workshop is used to control and slice 3D models. Download Creation Workshop here.


Here is Instructables page of a project with detailed build guide, software and everything nneded to build it:

http://www.instructables.com/id/Little-Dipper-SLADLP-3D-printer-for-under-500-proj/

This project was developed by Instructables user "marshallpeck". Kudos to you sir! You can also see more at: https://www.facebook.com/protobuilds/ or http://protobuilds.com/ .

All the recent developments in SLA 3d printing make me think that it is the future for home and hobby 3d printing. We need more affordable resin materials and more low cost parts.

UPDATE:

Thanks to Reddit commentator "Panaetius" here is a link where you can start to research on how to hack or prepare a DLP projector for using it for SLA 3d printing. It describes basic concepts and example of modifications to color wheel focus / lens mechanism and UV filters.

Autodesk makes their Ember PR48 resin open source

In an unusual move for such big corporation Autodesk has made their PR48 resin recipe open source.
Kudos Autodesk! They even announced that they will make their Ember DLP 3d printer open source also.
It is licensed under http://creativecommons.org/licenses/by-sa/4.0/

Here are the reasons for open sourcing it from the source webpage:
  • We have an open approach, and encourage the use of 3rd-party materials in our printer. We include 3rd-party materials in the defaults for Ember's online model preparation and slicer, and are adding more as we optimize their settings for Ember: you can check them out at emberprinter.com. (You don't actually need an Ember to use the site.) This Instructable describes how to test new resins:
  • Autodesk is thinking differently about 3D printing, and sharing under an license reflects our commitment.
  • Open sourcing our resin formulation is only the first step in the journey of opening our 3D printer and our Spark 3D printing platform.
Here are the ingredients:
  • Photoinitiator: 2,4,6-Trimethylbenzoyl-diphenyl-phosphineoxide (TPO) 0.40%
  • UV blocker: 2,2’-(2,5-thiophenediyl)bis(5-tert-butylbenzoxazole) (OB+) 0.16 %
  • Reactive diluent: Genomer 1122 19.89%
  • Oligomer: Ebecryl 8210 39.78%, Sartomer SR 494 39.77%
Are those ingredients even available for open sale?

Draken DLP SLA 3d printer is new challenger in affordable stereolithography market

Draken by 3DFacture is new DLP based LSA 3d printer that wants to enter affordable stereolithography market segment.

Key features from KS page:

  • Traditionally, 3D printers fall into two catergories: high resolution printers costing thousands of dollars, or low resolution ones costing under a thousand. The Draken prints at 37 microns on X-Y axis and can print down to 10 microns on the Z axis, which results in printing features as fine as a strand of hair.
  • Draken prints  up to 8.66" tall with a 3.86" x 7.09" build base at 90 micron XYZ resolution, the largest and tallest among all personal SLA printers.
  • Because 3D printers can take several hours or longer to complete taller builds, it's important to reduce the noise pollution as much as possile. Draken makes almost no noise.
  • Draken is one of the fastest personal SLA printers in the market today.  For other SLA printers to print a 6.5 inch Statue of Liberty with 100 micron Z resolution, it takes anywhere from 6 to 8 hours. With Draken, it only takes 3.6 hours.
  • The inner printer frame is made of an integrated piece of high-quality steel, the outer shell is a single piece of aluminum alloy sheet, which assures the stability and precision of the printer.
  • Draken is so flexible that you can easily take out the commercial-grade high definition projector and use it to project HD movies.
  • The patent-pending passive peeling technique in the build platform reduces the adhesion  force at each layer separation and increases the printing speed dramatically.
  • For most SLA printers on market, the resin vat needs to be replaced every few months, because the silicone coating on the vat might get cloudy after extensive usage. In Draken, we bonded a thin Teflon layer on top of the silicon coating, which greatly extended the lifetime of the vat. You won't need to worry about frequent replacement of the vat anymore.
  • Draken supports all third-party resins. We have tested several stable resins for Draken with various properties. MakerJuice, MadeSolid, FTD, and even Formlabs resin work perfectly with Draken. Furthermore, Draken's materials development team has created our own resin, priced lower than all the others on market.

EnvisionTEC high end 3d printers and bioplotter

I was just looking around what is industry standard and I found couple of videos from EnvisionTEC. They have some fine and expensive machines BUT as technology goes, one day you will have it on YOUR desktop.




... now, while you may have your workshop machine, most of you probably won't need a bioplotter since it is currently used as sophisticated medical instrument for special cases... or maybe DIY biohacking will explode. Making implantable 3d objects and body mods ... sounds like SF but we will see what future holds ...

Reify Solus DLP 3d printer

There are many new DLP based SLA 3d printers and Reify3D Solus is a new contender in the arena:

Technical specifications and features based on Solus Indiegogo page:
  • build area: 14.5 x 11 cm
  • made from thick, laser-cut anodized aluminum and stainless steel
  • z axis motor has an integrated lead screw with a anti-backlash nut for layer consistency
  • Solus will work with most non-LED DLP projectors and the addition of a close-up filter and adapter, or in the case of the Acer H6510BD, straight out of the box. And since the projector is not enclosed inside of the printer, it can be used to watch movies when you're not printing.
  • As with most DLP printers, the XY build area is dependent on the XY resolution you wish to print at. The maximum XY build area is 14.5 x 11 cm and the maximum height is 20cm. The extendable legs allow for a wide range of resolutions. For the projectors the company has tested the resolutions and build areas are as follows:
SVGA (800x600)
  • 70-180 micron XY resolution
  • 5.6x4.2x20cm - 14.5x11x20cm build area
XGA (1024x768)
  • 50-140 micron XY resolution
  • 5.1x3.8x20cm - 14.5x11x20cm build area
HD (1920x1080)
  • 25-76 micron XY resolution*
  • 4.8x2.7x20cm- 14.5x8.2x20cm build area
  • *25 micron XY resolution is not possible with all HD projectors.
  • Solus has been tested with resins from MakerJuice, Spot A Materials and propriatery formulations. The resin tank is made of acrylic and the peeling material is resistant to almost any chemical, so all resins that cure around 400nm should work. There are already a great variety of material choices ranging from ones as strong as ABS to flexible, castable and even ceramic filled
  • Price: 1199 USD range on Indiegogo

Abram Thau is 3d scanning people and printing figurines with homemade machines





Interesting video form Slashdot. You go Abram!

From source article:
When I bumped into Abram Thau at Metrix Createspace in Seattle's Capitol Hill, he showed me a few printed figurines, including a Storm Trooper (of the Star Wars variety), and I thought at first that he had printed them as duplicates of similar-sized commercial products. Not so: It turns out these are made-from-life, specifically from cos-players who have stood on Abram's human-suitable turntable (powered by a chicken rotisserie motor hooked to a 3-D printed pulley) while he scanned them in.
Thau's apartment is practically shouting distance from Metrix, but that pulley was made on a large Deltabot filament printer in the corner of his living room. (A living room usefully cluttered with tools, bottles of resin, projectors in various states of repair, and more printed objects.) More interesting still, Thau's figurines are produced with a home-built resin printer. Resin is messier to work with than the filament feedstock of RepRap/Makerbot style printers (and the resin itself has a slight odor), but it allows different results. Overhanging pieces are possible without requiring elaborate support pieces built into the mesh, and the resulting product can be noticeably smoother than typical filament printing, though all 3-D printing techniques are getting better. Thau didn't buy one of the commercially available resin printers, though (like FormLabs's), but instead decided to build his own out of scavenged and off-the-shelf components.
Budget concerns and improvisation rule the day (Thau is also a grad student, studying to be a middle school teacher): That means there's a book holding up the projector which is vital to curing the resin, and the printer's case is recycled from a previous one. The results look as good as the affordable commercial ones I've seen, and he's excited to teach others to make their own. Third-party resin makers and a robust market in used projectors mean that other hobbyists can follow his lead and turn their friends into figurines

Kudo3D Titan 1 high performance DLP SLA 3D printer



Kudo3D Titan 1 is a new high performance DLP SLA 3D printer in price range of Makerbot Replicator 2.

Kudo3D Titan 1 key features:
  • Stereolithography (SLA) printing technology: Bottom-up SLA configuration
  • Patent Pending PSP (Passive Self-Peeling) technology: 
  • Flexible resin container (VAT) design
  • Enhanced printing performance and quality
  • Simplified printer structure
  • Superior reliability: modularized with heavy duty high quality components
  • Adjustable DLP to optimize printing performance
  • Compatible to all SLA photoresins sensitive to 400nm light

Kudo3D developed and plans to patent passive self-peeling (PSP) technology:
Passive self-peeling (PSP) technology is a patent pending bottom up SLA technology created by Kudo3D to minimize the separation force between cured layers and the bottom of the resin container. PSP employs a flexible resin container consisting of 5 different materials to enable a self-peeling process that minimizes the separation force. Therefore, feature as tiny as a strand of hair or a big object as tall as 9.5 inches can be printed on the same machine. Equipped with PSP, the printer needs only one stepping motor. As a result, the printer is simpler, more reliable and easy to use. Since our PSP technology employed Teflon, our container is immune to the attack of more reactive resin that happens to most of our competitors. Users can use materials from any vendors by setting proper exposure time.
Technical specifications:
  • XY resolution: 37μm to 100μm
  • Z resolution: 1μm
  • Build Size:
  • 7.5″ x 4.25″ x 9.5″ / 19.2cm x 10.8cm x 24.3cm (WxDxH approx)
  • Maximum print speed:
  • > 2.7 inches / hr for xy:50μm and z:100μm resolution
  • > 1.3 inches / hr for xy:100μm and z:100μm resolution

Autodesk ignites the industry with Spark platform and DLP 3d printer





Here are some big news! Autodesk, the BIGGEST 3d design / CAD / CAM player, is getting into the 3d printing market with some serious technology: Spark software platform and their DLP 3d printer which is first hardware they ever produced.

The printer itself is not so interesting but the Spark platform could have an major impact on the future development since it is a 3D printing software platform that sits between digital information and 3D printing hardware. It will include the necessary algorithms (for example slicing and supports) to easily convert 3D models into the necessary format for 3D printing. It will also include tools for checking and repair of 3D models, utilities for print preview that are compatible with mobile and desktop operating systems, cloud connectivity, and the ability to publish and share models. Spark will be a highly extensible platform, with SDKs and APIs for software developers, materials engineers and designers who will be able to create software, services, and information on top of the platform.

Autodesk will license the basic aspects of the Spark platform for free to 3D printing manufacturers and software developers. There will be some restrictions and usage guidelines to ensure a consistent user experience.

It is also important to note that both machine and Spark software will be "Open", so not fully "open source" but some sort of open  licencing and access.

Interesting times are ahead...

Accelerating the Future of 3D Printing
By Carl Bass, Autodesk President and Chief Executive Officer
For years, I’ve been fascinated by the promise and frustrated by the reality of 3D printing. Today, Autodesk is announcing two contributions to help make things better. First is an open software platform for 3D printing called Spark, which will make it more reliable yet simpler to print 3D models, and easier to control how that model is actually printed. Second, we will be introducing our own 3D printer that will serve as a reference implementation for Spark. It will demonstrate the power of the Spark platform and set a new benchmark for the 3D printing user experience. Together, these will provide the building blocks that product designers, hardware manufacturers, software developers and materials scientists can use to continue to explore the limits of 3D printing technology.

Spark will be open and freely licensable to hardware manufacturers and others who are interested. Same for our 3D printer – the design of the printer will be made publicly available to allow for further development and experimentation. The printer will be able to use a broad range of materials, made by us and by others, and we look forward to lots of exploration into new materials.
The world is just beginning to realize the potential of additive manufacturing and with Spark, we hope to make it possible for many more people to incorporate 3D printing into their design and manufacturing process. Over the coming months we’ll be working with hardware manufacturers to integrate the Spark platform with current and future 3D printers. Both Spark and our 3D printer will be available later this year.

3D printing will make it possible for us to create all sorts of things we create today, better, and to create all sorts of new things that we haven't even imagined yet. If you are interested in working with us, sign up at www.autodesk.com/spark.

Autodesk DLP 3d printer (price will probably be in 5000 USD range)











Stalactite 102 HD DLP foldable 3d printer from Spain




New high definition DLP 3d printes comes from Barcelona, Spain. It also features different resin types like wax resin suitable for lost casting.

Stalactite 102 specifications:
  • Minimum layer thickness down to 25 microns (hardware can support layers as thin as 10 microns).
  • High DPI (dot per inch) density on the X/Y plane (100 microns NORMAL mode, 50 microns FINE mode).
  • High quality precision components.
  • Mechanized aluminum and laser cut steel components.
  • Innovative decoupled dual peeling system (patent pending)
  • Proprietary software with fast slicing and automatic supports.
  • Wide choice of printing materials: currently up to 4 different resins with a variety of properties.
  • Build Area: 102mm x 76,8mm x 180mm
  • It will be priced at 2.895€ (plus VAT where applicable) when available for direct pruchase 

They have also developed a palette of resins with different properties and applications:
  • STANDARD: Entry level resin. Affordable and suitable for general 3d printing needs, from figurines to maquettes or quick prototypes.
  • PROTOTYPING: A hard and thought material, aimed at print objects that require improved physical properties. It has similar properties as ABS or Nylon plastic. Ideal for electronic housings, cogs, Iphone holders
  • ELASTIC: A resin with very peculiar properties: It's elastic and flexible. This opens up a world of options for your prototypes and props!
  • WAXY: It demonstrates similar properties to investment casting waxes. Once you print your model you will be able to use the lost wax investment process and cast your designs to bronze, silver, gold or any meltable metal. This resin is particularly well suited for jewelers and miniature figurines manufacturers.
They claim their DLP technology is superior to laser based resin 3d printers because:

  • Resolution: With DLP (Direct Light Processing) we can reach feature details of 50 microns, which is a six-fold improvement compared to Laser 3d printers that are limited by the geometry of the Laser beam (pointer diameter, varying shape, focus and raster speed).
  • Build Times: The Stalactite 102 builds each layer within a constant exposure time, making the size of the object within the X/Y build area independent of the build time. It doesn't matter how many objects you fit within the build area, print times will always remain the same, depending solely on the number of layers in the Z-axis. There's no rastering time, no head or pointer movement process, as is prevalent in the FDM, Inkjet and Laser 3D printing technologies.

Stalactite is currently on Indigogo, ypu can get it at much lower price:

Aluminum frame DIY 3D DLP Printer by Dan Beaven

Dan Beaven build his own DLP 3d printer. Here are the results:

Dans DLP resin printer


DLP projector and mirror


AR15 rifle rail printed on this machine with graphite powder added into resin


The printer is built out of 1″ T-slot aluminum and has a NEMA 17 motor that provides the Y-axis movement along two linear rods for the vat. The Z-axis stage uses a NEMA 23 motor and has a whopping 14″ of travel. Combined with a 104mm x 204mm build plate, this DLP can print some large size objects.
To cure the resin, he is using a 1080p DLP projector (Acer H6510BD DLP) with no modifications. To conserve space, it is mounted at a 90 degree angle, and uses a small mirror to reflect the image onto the build plate inside of the vat.
To pump the resin in and out of the vat, it is using an industrial peristaltic pump bought off the eBay, it needs to be flushed with isopropyl alcohol after each use!

Asiga Pico 3d printer with solid state UV LED light source




Asiga Pico is specialist 3d printer with size of a small kitchen countertop appliance. It is designed with jewelry, dental and medical industry in mind. It produces wax polymer casting for metal parts or uses medical grade biocompatible resin for things like hearing aids. It is priced at USD 6990. It comes with Asiga Composer software.

The Pico is the first 3D printer of its kind to use a solid state UV LED light source. The LED lifetime is up to 50,000 hours and is not classed as a consumable, unlike other systems. The result is consistent curing from layer to layer, day after day, year after year. UV light allows broader materials choices, such as water-clear and pure white materials.
The Pico now has an improved resolution of 39 micron pixel size with a build envelope of 40 x 30mm (X and Y), and a build height of 75mm (Z). With the ability to grow parts in 1 micron increments in Z, the Pico is ideal for high resolution applications such as dental, jewelry and hearing. When building at 50 micron layers, the Pico achieves a build speed of approximately 6mm p/hr.
