It's about slowing down likely taking stock of your physical world , your technology , figuring out how it's made , and figuring out how to improve it , and by extension , how to improve the quality of your life in the process .

It was never about producing models for 3D printing or other computer-assisted manufacture techniques . But what was cool about POV-Ray was that , at least in its native implementation , there was no GUI or WYSIWYG interface . To make POV-Ray models , you used a text editor to program objects using so-called constructive solid geometry CSG techniques , in which complex forms were built up as unions , differences , and or intersections of primitive shapes like cubes , circles , and prisms . It was all done in a special programming language native to the POV-Ray environment . To see what you'd made , you had to render the . file

  • Bugs Brew PLA Direct

    Updated: 2009-11-24 20:16:00
    A team from South Korea’s KAIST University and the chemical company LG Chem, have developed a one-stage process which produces our favourite fabrication material, polylactic acid, and its copolymers through direct fermentation of starch. They've genetically engineered E.coli to do the job, which makes the production of PLA cheaper and more "commercially viable."There are undoubtedly patents on this, and I don't know how the separation process works, but cheaper biodegradable feedstock for the current generation of RepRaps and the ability to basically brew the stuff in a vat will doubtless have an impact on both RepRap technology and our greed for oil.Vik :v)

    : : RepRap : Blog Blog for the RepRap project at www.reprap.org a project to create an open-source self-copying 3D . printer Saturday , November 21, 2009 Moving towards production The Java driver software now handles multiple part printing reasonably well , though wrinkles remain . This tray of Mendel parts was printed on my old Darwin in six hours my new Mendel is still , as web pages say , Under Construction . Erik and Nophead's experiment of reversing the extrude motor at the end of each write has led to minimal PLA . string Ages ago Zach defined an XML multi-part file format for RepRap and Fab Home that should be pretty easy to implement that would allow one to store a whole tray of parts like this in a single file . The G-Code file generated to build all of them is also a single file of course . I have a few immediate things to do on the software firmware front like having an M code that sets the temperature and waits till the extruder gets there , as opposed to returning immediately one needs both then I'll implement that . That in turn should mean that Mendel is represented by between four Mendel and six Darwin files that one just has to load and print . Labels : factory

Basically , I printed a 5x20x145 mm bar guyed to pads on the . raft Some years ago , when I was working with HDPE on my Tommelise 1.0 Repstrap printer the big problem with HDPE , aside from a tendency to warp profoundly , was finding a surface that it could be printed on . I found that I could print on art store foamboard . This material is about a quarter of an inch thick , typically and consists of plastic foam sandwiched between two sheets of plastic coated paper . HDPE would stick to that quite nicely . Unfortunately , however , this material tended to perish when exposed to the hot extruder head of Tommelise 1.0. It also lacked the structural strength to resist the tendency of HDPE prints to curl at the . corners Recently , Bogdan Kecman , a Rapman user in Belgrade , has been making a serious effort at working through the problems presented by HDPE and

That done , I printed my guyed , 5x20x150 beam again using ABS and printing at 16.8 mm sec . I processed the STL using Skeinforge and used a 40 hexagonal . fill I removed the beam immediately after printing it . and stripped off the . raft I am not able to detect any bowing in the resulting beam . The raft on which the beam was printed was rather coarse as you can see in the pictures in the previous guying blog item . It may be that there is some very small amount of bowing that is lost in the roughness of the bottom of the print caused by the raft . If there is , I suspect that it is much less than 1 mm over the 150 mm length of the . beam The STL for the beam with the guyed flanges looks like this . I would appreciate it greatly if others would try to print this beam in ABS on other Reprap printers so that I can confirm my results . If you are interested in trying this you can

  • Guying long prints

In the Middle Ages , architects compensated for the lateral thrust generated by domes and vaults with butresses . In the 20th century architects dealt with inflatable buildings by using guy wires to anchor them to the . ground When you print long , tall objects in most polymers the ends of the object tend to try to lift off of the print surface . Ordinarily , one uses a raft to more tightly secure a printed object to the print surface . For objects up to about 40 mm that method works nicely . When one goes beyond that , however , the printed object tends to peel the raft off of the print . surface I spent a lot of time working with HDPE several years ago . HDPE has terrible tendency to curl at the edges . At that time , I thought it would be a good idea to print pads next to the ends of a long printed object and guy the ends down . This spreads the force generated by the upwardly curling printed object . You can see a

    : : RepRap : Blog Blog for the RepRap project at www.reprap.org a project to create an open-source self-copying 3D . printer Tuesday , November 10, 2009 Reprapable Solar Power We've discussed reprapping solar panels for a long time , and of course our semi-conductor printing capability isn't quite up to that . yet But it should be possible to reprap a small-scale solar array like a miniature version of the industrial one at Daggett . above It would use reprapable solar-powered steerable mirrors . Those would be an autonomous motorized gimbal mirror support with a tracker that keeps the sun's reflection pointing the same way at all times onto a solar boiler , say The idea is you'd reprap out a load of these , then walk round a field putting them down . They'd all align themselves and start delivering solar power . I think the trick is to black out a corner of the mirror except for a small circular spot in the middle of the black . Each steerable mirror has a detector on a flexible arm that you place where you want the reflection of that spot to be . Feedback keeps the spot-reflection on station , and hence the main mirror also on station . A really clever design would combine the
