New York designer Michael Schmidt and architect Francis Bitonti have created a 3D-printed dress for burlesque dancer Dita Von Teese. Images above and top by Albert Sanchez. Designed by Schmidt and generated by Bitonti, the floor-length nylon gown was made using selective laser sintering (SLS), where material is built up in layers from plastic powder fused together with a laser.
Combination CNC Machine and 3D Printer How to make your own 2D CNC machine that converts into a 3D Printer and back to a CNC machine in less than an hour. Costing less than a CNC machine or 3D printer! (~$1,000.00) In addition, the design will go further than the traditional 3D printer printing ABS/PLA, and move forward to printing with new materials such as 3D Printing Nylon derivatives like tauman 618 as well as Acrylic and PET. Latest Updates to this Instructable as of 9/12/2012: 1. There is a full 2BEIGH3 update here, along with a source for Nylon 3D Printing material here.
Inkjet powder 3d printers provide a useful case study for the effects of university exclusive patent licensing. In the early 90s, MIT researchers developed inkjet 3d printers. They built off much of the technology platform used for selective laser sintering powder-bed printers, which had been developed at the University of Texas in the mid 1980s, with a series of patents issuing. Here’s a brief overview. The feed and build tables, the counter-rotating roller used for spreading the powder, and the idea of storing a control file in computer memory to control the build were all out there, available to be used.

This is an important time in the development of 3d printing. We have just cleared nearly two decades of the fundamental MIT patents on 3d printing using powders, and although there is a tangle of improvement patents on particular forms of 3dp technology, we have some hope of opening up development activities from its university-created, monopolistic roots. Recently Michael Weinberg at Public Knowledge published an important essay on the prospect of intellectual property issues slowing the development of 3d printing. Public Knowledge has spent a great deal of time dealing with digital copyright issues. Weinberg worries that manufacturers will sue 3d print users for making copies of their products, or replacement parts. Scorching the 3dp Earth
Calibration This page has been flagged as containing duplicate material that RepRapSoftwareTweakingManual also attempts to cover.These pages should be merged such that both pages do not attempt to cover the duplicate topics. Calibration is the collection of mechanical "tweaking" processes needed to get exact, quality prints. While your reprap machine may be working as far as the electronics are concerned, calibration is necessary to have well printed parts. Without calibration, prints may not be the correct dimensions, they may not stick to the build surface, and a variety of other not-so-wanted effects can occur.

RepRap takes the form of a free desktop 3D printer capable of printing plastic objects. Since many parts of RepRap are made from plastic and RepRap prints those parts, RepRap self-replicates by making a kit of itself - a kit that anyone can assemble given time and materials.
