2 weeks ago Father Christmas delivered a MakerBot Thing-O-Matic 3D Printer to my office. I think I understand how it must have felt to own an Altair 8800 back in the day when the world was on the brink of the consumer computing revolution. Consumer 3D printing could be another such revolution. But to print something in 3D you have to create a 3D model, and my survey of the software tools available for 3D modelling has been very disappointing. They broadly fall into the following categories:
DIY 3-dimensional additive fabrication and personal manufacturing are rapidly expanding areas of exploration for hobbyists, amateur engineers, tinkerers and Maker-folk. The development aims to provide an alternative or complement to capital-intensive mass manufacturing for individual-level consumption, and also aims to empower the individual in the design and creation of their own goods. Because of the involvement of many demographics including said amateur engineers and hobbyists in this “research”, potential breakthroughs for the additive fabrication industry as a whole are also promising. As the technology continues to evolve on a grassroots level, the quality of products and streamlining of the process should approach or overtake levels achieved by commercial additive fabrication machines while remaining accessible to persons interested in pursuing engineering as a hobby or profession. I mean, besides all that, I want my own 3d printer. So here’s a page listing my development work.
hi folks, i'm a bit sleepy, but i thought i'd post this while it's fresh: after seeing really interesting powder-based printer designs like this one , that place down a layer of powder then "print" a binding material onto it, i began to wonder (as others have) if we could build a similar setup using ABS powder and a laser diode to fuse the material together. designs like this have a bunch of benefits, including the potential to use the powder as it's own support material. (and, after a few weeks of tinkering with building an extruder for a second printer that *constantly* clogs, i think i needed a break to think about better days when we won't need to rebuild extruders, or hope we build working ones in the first place... ). my goals for this tinkering are to build things with common off-the-shelf materials wherever possible, and so I went searching for some form of ABS powder, as well as a laser diode.
NEWS: Come to the Inside 3D Printing event in New York City ! The event runs from April 22-23 2013. We have arranged for reprappers (that's you!) to get a special 15% discount on admission - quote the code RRP15. RepRap is humanity's first general-purpose self-replicating manufacturing machine .
