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...



3D Printing History 6 - Small Soldiers

Here is probably one the first appearance of a 3d printer in mainstream cinematography. It was in a movie named "Small Soldiers" from 1998. My kid brother really liked that one.

They show an early stereolitography machine, the model looks realistic when it comes out of the resin tank, but the process was made to look faster and with visible lasers.




Here is the video from YT:

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.

Prusa I3 Based Ultrasonic Laser Resin 3D Printer

Team of scientists hacked a Prusa I3 to develop new 3d printing process that uses laser to solidify ultrasound arranged resin fiber particle in a small vat.
A laser diode module was mounted on the print head to cure the resin, with an emitting power of 50 mW. The laser diode was housed in a shroud, and was focused using a single 6 mm diameter lens, with a focal length of 20 mm. The small vat sized at 35mmx35mm was filled with low viscosity photocurable resin (Spot-A LV) and commercially sourced glass microfibres (Lanxess MF7904, length 50 μm, 14 μm). Ultrasonic transducer gives resin floating fiber the shape and laser solidifies it.
It is a new form of stereolithography which could see some upscaling into more capable machines.

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

Resin based 3d printable ceramic with high-end properties





Scientists at HRL developed new resin ceramic material that can be 3d printed using stereolitography and has high strength and resistance to temperature. Amazing advances!


Project summary:
Researchers at HRL Laboratories, LLC, have achieved a new milestone in 3D printing technology by demonstrating an approach to additively manufacture ceramics that overcomes the limits of traditional ceramic processing and enables high temperature, high strength ceramic components.
HRL’s Senior Chemical Engineer Zak Eckel and Senior Chemist Dr. Chaoyin Zhou invented a resin formulation that can be 3D printed into parts of virtually any shape and size. The printed resin can then be fired, converting it into a high strength, fully dense ceramic. The resulting material can withstand ultrahigh temperatures in excess of 1700°C and exhibits strength ten times higher than similar materials.
Ceramics are much more difficult to process than polymers or metals because they cannot be cast or machined easily. Traditionally ceramic parts are consolidated from powders by sintering, which introduces porosity and limits both achievable shapes and final strength. "With our new 3D printing process we can take full advantage of the many desirable properties of this silicon oxycarbide ceramic, including high hardness, strength and temperature capability as well as resistance to abrasion and corrosion." says program manager Dr. Tobias Schaedler.
The novel process and material could be used in a wide range of applications from large components in jet engines and hypersonic vehicles to intricate parts in microelectromechanical systems and electronic device packaging.

The HRL team’s research paper, "Additive Manufacturing of Polymer Derived Ceramics," has been published in the January 1st issue of Science.



Form 2 is a New FormLabs Flagship SLA

Formlabs just released Form 2, the new desktop SLA machine. It is a 40% larger 3d printer than its predecessor. You can find all the specs on their page, it wil be priced at 3499 USD range.

Great step forward!

Only thing that drew my attention is their new "Automated Resin Systems". It looks like proprietary cartridge and it has an ID chip. I'm not a big fan of that setup but they claim you will be still able to use and experiment with third party resins in "Open Mode". We will see how this situation develops. If they close their machine so it can only use Fromlabs resin, someone will probably hack it making chip protection obsolete.


There are still no third party reviews or tests.

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:

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.

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.

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

OpenExposer low cost open source SLA 3d printer





Mario Lukas developed OpenExposer, low cost open source SLA 3d printer. OpenExposer is much more than just a 3d printer, it can also be used as UV PCB exposer, laser harp or show laser. It will have different modules for different uses.

Mario writes in project comments:
"The main focus of the OpenExposer Project is on the little red box which should contain all electronic and optical parts. This box should be clampable to different modules. The 3D printer which i am building currently is only one of those clampable modules. For PCB etching i am planing to design a module which works like a laminator."
The frame is made from standard RepRap rods and parts. The main part of 3D printer system is a small slit cut into the bed, and a build platform that moves in the Z axis. The bed contains a  UV laser and a polygon mirror recycled from a junk laser printer. By moving the bed in the Y direction, laser can be targeted anywhere on an X-Y plane. By adding a tank filled with UV curing resin on the bed there is a complete SLA printer.

It is currently still under heavy development but it looks very promising. There will be many problems to solve like varying focal length laser traces the arc from the polygon mirror since laser printers use a specialized type of lens to insure the focus is consistent, allowing a consistent spot size over the entire sweep of the beam.

Mani features:
  • unit for multiple laser exposing processes 
  • Arduino compatible 
  • low cost (standard laser printer) parts 
  • case parts lasercut or 3d printable 
  • up to 2 stepper motors can be connected 
  • additional I/O ports for custom extensions 
  • simple protocol 
  • extendable host software

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)

T.Black DLP 3D printer by Trimaker made in Argentina

South America is also developing more 3d printers. Here is T.Black DLP printer by Trimaker from Argentina.




 

























Specifications:
  • Build volume: 180 x 235 x 180 mm
  • Positioning precision: 250 microns
  • Print speed: 20mm ~25mm / hour depending on the dye and the material.
  • Materials: rubber, rigid plastics and low viscosity plastic
  • Weight: 18kg
  • price: 38,720 Pesos ($4,936)

From company page:

PRINTING TECHNOLOGY
The printer is T.Black based stereolithography technology - the selective polymerization of the liquid resin with light. Unlike other inexpensive printers like MakerBot and RepRap, the Trimaker printer does not use a power head for depositing material during the printing process. Instead of using a head, the T.Black constructed by drawing the print object layer by layer with an optical projection - each layer of the object is actually a photo of each cross section. For each layer, the Trimaker projecting a light pattern on liquid resin solidifies and thus the parts constituting the object. The remaining resin can then be used as input for the next printing.
Advantage
More reliable technology.  T.Black technology is much more reliable because the control of complex mechanical movements is the part that usually fails. · High Resolution. Whether using light to build the object layer by layer allows a degree of much finer and more precise control. The resolution of your printer is more than 10 times higher than other inexpensive printers based on the technologies FDM (fused deposition modeling). The print resolution is one of the most important features that makes the difference between something with the quality of the prototype and the quality of the finished product and this is the main advantage of stereolithography technology. · Control of Color. use of liquid chemicals allows very flexible control of color printing. The user can change color very accurately by adding the proportion of dye which gives exactly the desired color. · Control of Multiple Properties. stereolithography process works with a variety of inputs. The designer can choose from a variety of materials with different degrees of hardness, density, transparency and other properties.

MADE IN ARGENTINA
The fact that both the hardware, software and materials develop in the country, are a great advantage for our clients when thinking about the after sales service, spare parts, supplies and personalized attention. Delivery times, technical support and input supply is greatly reduced on options imported printers today are available in our market. Finally, being a company Argentina, we will make all our releases, product testing, lectures and trainings, first in this market.
I'm not sure what technology tehy are describing in "control of color" part ... probably just a single tone of color in the resin ..

From DIY 3d printing history 3 - CNN interview with Chuck Hull






"The night I invented 3D printing" CNN interviews Chuck Hull

Chuck Hull (75) is the co-founder, executive vice president and chief technology officer of 3D Systems. He is the inventor of the solid imaging process known as stereolithography (3D Printing) in mid 1980s, the first commercial rapid prototyping technology, and the STL file format. He made on more than 60 U.S. patents as well as other patents around the world in the fields of ion optics and rapid prototyping.”

But, was Chick the first to develop 3d printing technology? Maybe not ... more soon ...
