3d printing with UV light curing resin

Phantom Geometry from Liz and Kyle von Hasseln on Vimeo.

This is ‘Phantom Geometry’, a masters thesis in architecture by Kyle von Hasseln and Liz von Hasseln, developed in the Robot House at the Southern California Institute of Architecture (SCI_Arc). It was awarded the inaugural Gehry Prize at the SCI-Arc commencement ceremony on September 9.

This work is centered on the development of a system for generating material volume from streaming information. The system uses UV light from a modified DLP projector to continuously and selectively cure photo initiated resin within a shallow vat system we developed for the project. The cured part is simultaneously and continually pulled away from the vat, allowing un-cured resin to flood in beneath it to be subsequently cured. The result is the material reification of streaming data that emerges along the motion path of the Staubli robot maneuvering the vat/projector apparatus.

This system of fabrication relies upon native real-time feed-back and feed-forward mechanisms, and is therefore interruptible and corruptible at any time. The streaming data input may be transformed or modified at any time, and such interventions impact emerging downstream geometry.

Rostock MAX

Currently on Indiegogo

From their IndieGoGo page:

Advantages of the Delta Arm design:

  • MUCH faster Z axiz movement.  A traditional 3D pritner design uses threaded rods or acme screws.  These severely limit the Z axis speeds to about 200-400 mm/min speeds.  With the Rostock MAX, we have the same speed in X/Y as we do in the Z, which is up to 40000 mm/min.  Holy Cow right! 
  • Counter acting forces of movement.  With a traditional pritner again, you have a carriage moving left/right or front/back, and it has to overcome the weight of that movement to reverse it's direction.  We use accelaration to tune the motors DOWN to slow the speeds of the carriage when it's near the end of a move so it doesn't "whip" or chatter, when changing directions.  With the MAX, all three carriages have to move together to make coordinated motion, so if one arm has to go up, the other two have to go down, and this cnacels out a huge amount of the inertia in the movement at the head, so we can tune the motor to a much higher rate, increasing the speed.
  • Circular motion is smoother by default with the Rostock MAX.  The delta arms also have a unique feature, SUPER ROUND CIRLCES!  Now, yes, you can have the same smooth circles with a standard printer, however, you have to work to get it to make those circles very round.  The reason is you have two straight lines, one in the X and one in the Y, and you have to vary those two lines to make a circle.  Any backlash in the belts/pulleys etc... will cause the circles to come out egg shaped at best.  With the MAX, circles are more true, becuase any backlash that could exist is cancelled out by the fact that the platform "hangs" from the arms, and gravity takes care of the rest.  There are other reasons too, such as that every single move sent to the printer is split into 200 seperate movements.


  • Approximate 10"+ Diameter x 13" + High build volume
  • Sturdy design using bolted together parts
  • Precision laser cut, CNC and injection molded parts
  • Designed for english OR metric hardware
  • Windows, MAC, and Linux compatible with OS software
  • Uses UltiMachine RAMBo electronics
  • Uses Standard NEMA 17 motors and GT2 timing belt
  • 15 Tooth motor pulleys
  • Filament is held by the machine, no more tangled spools on the floor
  • Wide open access to the build area, easy to get at parts
  • Unique design lends to easy modification for other uses
  We are looking into other "tool heads" to attach to the platform.  Some easy to convert ideas are pick-and-place vacuum head for electronics board assembly, sodler paste syringes for PCB prepping, pen mount (it's the $25 perk) for plotting/drawing and even a low power laser platform should be easily adaptable.
 We are also going to be using UltiMachine's new electronics boards, the RAMBo. They have the ability to run two extruders, one heated bed, and up to 5 stepper motors.  Check out theRAMBo wiki page to learn more about these really awesome 3D printer electronics from UltiMachine.  The boards have 5 allegro A4984 stepper drivers, two plugs if you ever need a dual-z motor setup etc..., 4 thermistor inputs, and so many more awesome features. 

More information about our Rostock MAX can be found online over at theRepRap project, as well as our Forum.  We will be posting build instructions, CAD files, firmware settings and more, all on ourRepRap.org Wiki Page

Filament makers

Usually if you want to print something you need to have filament to feed your 3d printer. But, what if you could recycle your failed models or even recycle waste plastic and make f3d printing filament out of it? Basically suitable junk plastic is ground up, continuously pressed and melted trough extruder similar to the one on 3d printer and after cooling you get filament ready for next print job.  Currently there are two projects that I know which are developing usable technology. They are in various stages of development and availability, let's hope that this technology goes into full implementation. 


From filabot.com :
Filabot is a desktop extruding system, capable of grinding various types of plastics, to make spools of plastic filament for 3D printers. Not only is it user friendly, but it is also environmentally friendly. The Filabot can process things such as: milk jugs, soda bottles, various other types of plastics, and bad prints, to make new filament for a future print. Filabot will bring the real power of sustainability to 3D printing, allowing for a one stop shop to make anything.

Lyman Filament Extruder 

From http://www.thingiverse.com/thing:30642 :
The Lyman Filament Extruder is a machine that extrudes filament from pellets for use in a 3D Printer. It can extrude 1.75mm and 3mm filament with easy nozzle exchange. The material cost is about $250.
On their thingiverse page there are plans, files and guides available.

3d printing DRM patented

Here we go again with all the DRM stuff. 3d printing DRM is patented. When will they figure out that patent system is broken and DRM does more harm than good? From the looks of it, the guy is just setting up generic patent so he can potentially patent troll future 3d printing DRM system proprietors.

Article summary:

Sometime in the none-too-distant future, replacing your favorite coffee mug or creating a new iPhone case might be as simple as downloading a design you like from the Internet and firing up your 3-D printer.
Most 3-D printing has been done in industry or by hobbyists who share their designs freely online. Now Intellectual Ventures, the company run by Nathan Myhrvold, the former Microsoft CTO and alleged patent troll, has been issued a patent on a system that could prevent people from printing objects using designs they haven’t paid for.
The patent, issued Tuesday by the U.S. Patent & Trademark Office, is titled “Manufacturing control system” and describes methods for managing “object production rights.”
The patent basically covers the idea of digital rights management, or DRM, for 3-D printers. It also covers using digital files in extrusion, ejection, stamping, die casting, printing, painting, and tattooing and with materials that include “skin, textiles, edible substances, paper, and silicon printing.”
Control schema: A drawing from a patent won by Intellectual Ventures describes how to control digital rights for 3-D printing.
“This is an attempt to assert ownership over DRM for 3-D printing. Myhrvold’s operation, based in Bellevue, Washington, basically exists to file and buy patents, and currently controls nearly 40,000 of them, according to a spokesperson.
The manufacturing control patent, number 8,286,236, was filed back in 2008 and issued on October 9 to Invention Science Fund I, an arm of Myhrvold’s company.
