The Effect of University Monopoly Licensing in 3d Printing | Research Enterprise 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. The idea of building things out of powders in layers goes back yet earlier–to at least the work of Ross Housholder, who patented in 1981 an approach using heat to selectively bind powder deposited in layers. In 1979, Joseph Beaman, with a doctorate from MIT, goes to the University of Texas and coins the term “solid freeform fabrication”. 1. This is pretty basic. 1. 1. 2. 3. 4. 5.
Scorching the 3dp Earth 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. These are important things to consider, but I fear the biggest threat to 3d printing may well be coming from universities, and in particular from university technology transfer offices fixated on filing early-stage patents and holding to a coarse idea of “commercialization”, which to them means “make money by licensing”. This activity is said to be in the public interest. Look at 3d printing. There’s another argument that says: “who cares if it is a public benefit?
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. ANNOUNCEMENT: If you search for the latest up-to-date guide please take a look at Triffid's Guide. 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. Once you have finished the physical build of your RepRap printer, calibration is the next big hurdle. The following set of objects and notes are taken (and edited) from Coasterman who posted them to Thingiverse. Before attempting calibration, a few things are necessary: Motherboard Symptoms Glass
RepRapWiki RepRap is humanity's first general-purpose self-replicating manufacturing machine. 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. It also means that - if you've got a RepRap - you can print lots of useful stuff, and you can print another RepRap for a friend... RepRap is about making self-replicating machines, and making them freely available for the benefit of everyone. Reprap.org is a community project, which means you are welcome to edit most pages on this site, or better yet, create new pages of your own. RepRap was the first of the low-cost 3D printers, and the RepRap Project started the open-source 3D printer revolution. RepRap was voted the most significant 3D-printed object in 2017.
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. 2. As a sample of the unique new properties of just one of these new materials, Here is a 3D Print of a Childs NYLON Prosthetic Insole on the 2BEIGH3 3D Printer. With the 3D Printer configuration of the 2BEIGH3, you will be able to print parts that meet much higher standards for strength, flexibility and pliability.
3D-printed dress for Dita Von Teese 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. The rigid plastic components are fully articulated to create a netted structure that allows for movement. Draped over a nude silk corset, the black-lacquered dress is cinched in at the waist and exaggerated at the shoulders, and embellished with 12,000 Swarovski crystals. It was unveiled during an event at the Ace Hotel in New York earlier this week, as part of a showcase of products organised by 3D printing marketplace Shapeways, who printed the dress and were also behind the 3D-printed bikini we showed a couple of years ago.
