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

mUVe developed improved Marlin firmware

mUVe 3D creators in cooperation  with Tim Schmidt and the Lansing Makers Network developed improved Marlin firmware version that can also work with with laser cutters, UV laser printers and has some more advanced options.


From source article:
This is a huge addition to the functionality of the Marlin firmware and it will allow a huge array of hardware to be run. It’s no longer a firmware for just FFF machines, we can now make laser cutters, and laser based 3D printers. Best of all, it’s a HUGE improvement to print quality and will help your QSil and Sylgard last much much longer than before! Look at all the additions!
  • mUVe 3D specific peel move still exists and is a function that can be turned on and off before you compile, so now you can use the firmware on other SLA based machines without edits.
  • Use hardware other than Arduino Mega 2560 and RAMPS, you can select the machines on the list that have enough memory to install it. It has grown in size, chips with less memory may be an issue but this hasn’t been investigated yet.
  • Firmware defined laser point size for future features such as W/cm^2 calculation and auto-laser-power setting for resins with W/cm^2 data available.
  • EEPROM saves the amount of time the laser has been on and will tell you when you boot how many hours and minutes the laser has been used.
  • PPM laser pulsing with specific maximum frequency set in Hz.
  • Laser pulsing built right into stepper code so there is no added processing time, delays, or otherwise. Full speed printing.
  • Configurable laser power on a scale of 1-100.
  • Configurable pulses per mm, default of 10.
  • Configurable time on for each laser pulse in microseconds, default is 3000.
  • Default connection speed lowered to 115200 for compatibility with more computers.
  • Built on and compiles with the latest version of Arduino, main file is now Marlin.ino.

axCut DIY laser cutter

Damian Axford is developing new open source DIY laser cutter. axCut is influenced by nopheads Mendel90, BuildLog 2.x and Lasersaur. It is still under development but it looks very promising. I'll follow the project since I'm getting more and more interested in laser cutters.



axCut project requirements:
  • 40W CO2 laser (with space to upgrade to at least 80W - i.e accommodate a 1000mm tube with water cooling)
  • Bed size to accommodate A1 stock - design files use 850mm x 600mm with 30mm margin all round
  • Fully enclosed
  • Allow for pass-through (i.e. very long items)
  • Allow for high/tall items and "autofocus" via motorised bed (150+mm travel)
  • Have unobscured front access for loading/unloading parts
  • Bench-top design (may integrate a bench at a later date)
  • Side connections for extraction and cabling (i.e. power, usb)
  • Investigate using reprap s/w stack vs Mach3 - I'd really like to leverage as much as possible from the reprap community (e.g. modified sprinter firmware)
  • Budget target of £1500 (max £2000)

PCB etching with UV laser on Pegasus Touch SLA 3d printer

The Pegasus Touch team found out another use for their printer. UV laser can etch UV sensible PCB boards to make surface for electronic components. Pegasus Touch will get software upgrade to implement this function.
This could become standard feature in all UV laser equipped stereolitographic 3d printers, their software and drivers need some simple upgrades which will hopefully be provided by manufacturers or third parties.



One commentator on Hackaday noted:
Neat, but useful?
Currently I print my board on two transparencies, then aligning them on the UV-sensitized board, then placing whole thing under a UV light source. Two minutes of work followed by five minutes of wait?
This new method would have me remove the resin tank, align and mount the PCB to the build platform (double sided tape?), convert my gerbers to a jpg/bmp, then finally print to the 3D printer?
IF it’s saving time/money, it doesn’t appear that significant. Maybe if mounting and aligning the PCB was very quick and easy? Although I’m imagining a frustrating process involving double-side tape and wasted copper clad trying to correct the alignment.

So, this function could be useful in some situations and usage scenarios, but you will get the PCB etching job done faster if you are experienced user. This upgrade is simple software addon, so it is nice to have some extra features in a single machine.

Advancements in nano scale 3d printing by Jan Torgersen of TU Wien

It is not 3d printing if it 's not nano scale 3d printing.



From video description:
After his studies in mechanical engineering at the Vienna University of Technology, Jan Torgersen started his phd work at the Insitute of Materials Science and Technology. Jan's field is Additive Manufacturing Technologies; the technology involved in 3D printing. He developed a new printer that is able to produce nano-scaled objects suitable for numerous applications in photonics, surface modifications and biomedical engineering. This printer is currently the fastest of its kind and brings the technology closer to industrial applications. How it works got illustrated recently by a video that went around the world, showing the construction of a racing car model in the scale of a human hair.
In the video, a race car with dimensions of 330x130x100µm3 is fabricated. The structure consists of 100 layers, each made of an average of 200 polymer lines. It is finished in 4 minutes and resembles the CAD file at a precision of ±1µm.

Pegasus Touch Laser SLA 3D Printer





Full Spectrum Lasers is developing this laser SLA 3d printer. Lasers are way to go. This is also a great example how advancements in one technology, like cheap blue ray laser diodes, leads to advancement in another technology like 3d printing.

Technical specifications:
  • 3D Technology: 405nm scanning galvo laser liquid resin stereolithography
  • Build area: up to 7”x7”x9” (177x177x228mm)
  • Case Footprint: 11"x14"x22.5" (280x360x571mm) 
  • Processor: Built in 1GHz Linux computer with 512mB memory and 4.3” Touchscreen LCD Interfaces: Ethernet, USB, WiFi (requires optional USB dongle) 
  • On Board Software: Built in on-board Internet Connected 3D Printer App Store (no computer required) 
  • Desktop Software: Tightly integrated multi-touch capable desktop software with automatic slicing and automatic breakaway support generation with manual editing support for Windows PC (Mac coming soon) 
  • Speed: up to 3000mm/sec (>10x faster than most FDM, up to 6x faster than other SLA)
  • Focused Laser Spot Size: ~250 microns 
  • XY Positioning Resolution: 16bit precision, ~3 micron 
  • Z Motor Resolution: ~5 micron (typical layer thickness 25-100 micron)

Pegasus Touch main features from Kickstarter page:
  • Touchscreen LCD desktop 3D printer starting <$2k using LASER based tech for high speed prints, 7"x7"x9" build area, and detail.
  • As designers and engineers, we have found lasers and 3D printers to be amazing tools. Naturally, we wanted to combine the two and build a 3D Printer with lasers! Thanks to the wide adpotion of Bluray players, low cost near UV laser diodes which can cure liquid resin are now readily available making high quality 3D printers a reality. 
  • Using software/electronics technology developed for our laser cutting/engraving products, we’ve perfected an affordable high quality laser based Stereolithography (SLA) 3D Printer that sets a new standard for desktop 3D printing for every maker and maker to be. Starting below $2000 on Kickstarter, Pegasus Touch produces by far the best quality 3D printing output for its price.
  • Speed: Controlling lasers properly takes years of experience. Pegasus Touch’s advanced control electronics can pulse its laser source at over 500kHz while moving the laser beam at 3000mm/sec thanks to the same special FSL real-time laser processor used in $100,000 scanning laser systems. Faster laser control allow us to tune the resin to cure more quickly without sacrificing quality allowing for up to 10x the speed of FDM printers and 3-5x the speed of other SLA printers.
  • Output Quality: Nearly all current low desktop 3D printers below $3000 use FDM technology but Laser based SLA technology has set the gold standard for quality since it was invented in the 1980s. Due to finer control offered by laser technology, the finish of laser based SLA printers is just better.
  • Affordability: Starting below $2000, Pegasus Touch is the lowest cost assembled SLA printer available – it’s even less expensive than many leading consumer FDM printers. Pretested, fast, high quality resin is available at only $100/liter.
  • Standalone Ease of Use: Other low cost printers transfer several gigabytes of post processed data from a tethered PC. Pegasus Touch has an on-board Linux computer that can do much of the 3D processing computation on the printer itself. Typical transfer file sizes are only a few megabytes so it never needs to be tethered to another computer. 
  • By putting a full internet connected touchscreen computer right into the printer, FSL3D has been able to build a 3D Printer App Store right on the printer. Find high quality, pretested models right from the printer itself - no more digging endlessly or tweaking to find perfect printable 3D models.

Early attempts in DIY laser sintering by Replaser from 2010

Some attempts at DIY laser sintering from 2010 with a 250mW laser, plastic powder and thermo-gel. It was noted that 1kg of powder costs about 3-5 Euro and 50ml of gel cost about 5-6 Euro. Since then some advancements were made by other in the field., but it is interesting to see early experiments.

Skull shaped microscopic 3d printed bacterial cages

From the source:
By caging bacteria in microscopic houses, scientists at The University of Texas at Austin are studying how communities of bacteria, such as those found in the human gut and lungs, interact and develop infections.
In a recent experiment they demonstrated that a community of Staphylococcus aureus, which can cause some skin infections, became more resistant to antibiotics when it was contained within a larger community of Pseudomonas aeruginosa, a bacteria involved in various diseases, including cystic fibrosis.
The work was published this week in the Proceedings of the National Academy of Sciences.
The researchers use a novel 3-D printing technology to build homes for bacteria at a microscopic level. Their method uses a laser to construct protein "cages" around bacteria in gelatin. The resulting structures can be of almost any shape or size, and can be moved around in relationship to other structures containing bacterial microcommunities.
The method should enable an entirely new class of experiments that better approximate the conditions that bacteria encounter in actual biological environments, such as those in the human body.

DIY laser 3d printer by Moritz Walter - video of the first print

Moritz Walter presents his DIY laser resin 3d printer. Video shows first print and basic information about it, I hope more details will follow.




From video description:
The very first print on my diy 3d laser printer. It should be a cube but it's just a small quadratic mess ;) It's using a 500mw 405nm laser on a custom made stepper motor driven xy-mirror deflection system. Using steppers instead of galvos might be unconventional, but saves you the necessity of high accuracy DACs in addition to a row of calibration steps and DSP. Steppers work just fine OOB with optical endstops while delivering quiet good accuracy proven on many FDM-machines out there. The z-Stage works well with a 0.9° stepper motor, but the surface of the print stage's not sticky enough to pull out the printed part out of the ptfe-covered vat.
However, mind that this is only a very first test, I only spilled a small spot of the expensive Spot-HT resin in the middle of the vat for testing the basic principle and functionality. All stepper motors are driven by a TB6560 based driver board. Main power source is a 300W pc power supply. I have implemented a fresh but teacup-flavored gcode-interpreter and a fully custom firmware on a chipkit max32 board, which offers speedy 80 MHz of floating point calculations for high-resolution vectorial mapping, pre-warping of incoming gcode and of course the necessary look-ahead, that is necessary for acceleration/deceleration.
Eventually it could achieve far more than 10.000 mm/s travel speed while still being able to pulse width modulate the laser intensity corresponding to it's current travel speed. For that, I will have to replace the current diy op-amp powered level shifter between the Max32 and the stepper driver with a FET-powered version, but for now it's running quiet well. In the video it's running at a low speed 500mm/s with a slow acceleration setting. Right now for testing I am using slic3r and the repetier host. Repetier is great, but one should really use skeinforge for professional printing. As you might have noticed the housing is a red IKEA box, which apparently seems to perfectly shield the 405nm laser light when closed (no guarantee for that, be careful with your eyesight when experimenting with lasers more than 1 mw). Thanks for watching, leave your comment, I'll be glad to see similar builds out there!

Lasersaur open source laser cutter project

Lasersaur is an open source laser cutter project that is well documented and has community behind it. If you want to make your own CO2 laser cutting system for cutting trough wood, paper or leather (and some other materials) this is a project you want to study.
There are some problems, bugs and issues so you should look at the extensive video in the bottom of the post.
