Re: Thingiverse Alternative poll on Reddit - 12 years ago
Hi Wil, Personally, I've used Public Domain, GPL, and BSD licenses for the designs I've published. It would be nice to have those options, but having only CC Non-commercial is not a deal-breaker for me, mainly because I assume everyone is going to ignore the license anyway. Of course, it complicates things a bit if I upload something to cubehero that I've already uploaded to thingiverse as GPL,by MattMoses - General
Re: Thingiverse Alternative poll on Reddit - 12 years ago
After checking out some of these sites, it seems like a lot of them are simply content scraped from Thingiverse, often without attribution. I remember Defcad was caught doing this a while ago (Thingiverse Scraped!). Some examples: Here is Richrap's paste extruder on a site called rascomras. Here is abauer's Anchor Chain Marker on a site called shapeking. Looks like we should screen the sitesby MattMoses - General

Great! It is nice to get this on the wiki. I made a few edits and additions. Everyone please feel free to add more!! What are people's thoughts on adding links to repositories with controversial or NSFW content, such as weaponiverse, defcad, dongiverse, makerlove, etc? Would it be worth the trouble to add flags for different types of content? For example, Thingiverse allows weapon accessories anby MattMoses - General

QuoteTwitchy I think any approach to print metal would probably be easier if it followed this already beaten path. Metal printing via FDM-like extrusion has been demonstrated too.

Re: Idea: A blacksmith bot based on Simpson - 12 years ago
Also check out Jeff Thompson's work on voxels. He did some experiments using a CNC to build things out of spheres. If you could come up with some kind of collet to hold the sphere, you could spin it like crazy and use friction welding. It may not have any advantages over spot welding, but some combination of spinning and zapping might work better than either alone. For example, spinning the spheby MattMoses - Delta Machines

Re: Wax printing - 12 years ago
A number of 3D printers on the market use wax inkjet technology. For example Solidscape. On the wiki, I wrote up some experiments on subtractive wax machining using a heated nozzle. It might be possible to "reverse" the process and do wax deposition with similar hardware, although getting an acceptable viscosity would be challenging.

Re: 3d printing using paper - 12 years ago
That sounds a little like ultrasonic consolidation, where they deposit strips of metal before milling them to shape (but in this case they are depositing before cutting). If you can recycle thin strips, wouldn't it be just as easy to recycle a big sheet? Or are you thinking that the strips would be so narrow that the cutting would essentially be a "digital" process, where thin strips are cut toby MattMoses - General
