January 21, 201016 yr comment_317611 Not audio related but damn it's cool: Video: MakerBot's build-it-yourself 3D printer in action, replicator in the works -- Engadget CupCake CNC - MakerBot Industries If I had somewhere I could put it I'd be all over it. That is flat out frigging cool. Custom heaphone stands, knobs, wtf else. So cool Report
January 21, 201016 yr comment_317618 I've used one of those that uses a laser to cure a vat of stuff.. milspec in fact, as it primary use was prototyping for aircraft. Pretty cool, and insanely accurate. Report
January 21, 201016 yr Author comment_317621 The price point on this bad boy is nuts though $950 for everything. Now I have to think of a use. Report
January 21, 201016 yr comment_317622 I'm actually pretty interested. I wonder what software it supports/needs? Report
January 21, 201016 yr Author comment_317623 Apparently it's totally free software once you can feed it an STL file which most any solid modeler will generate. Or there are lots of models on line to start. The plastic is the same stuff as for lego. I can see people doing some sweet diy enclosures etc Report
January 21, 201016 yr comment_317626 I was actually thinking about this for my real job, where I regularly work with architects who produce scale models of projects. But the DIY applications are pretty cool too. Report
January 22, 201016 yr comment_317891 I decided I'd call an expert and spoke with my brother last night who's a mechanical engineer and has quite a bit of experience with rapid prototyping machines like this. His advice was that if you expected anything other than a prototype out of it you were doomed to be disappointed. The 3 major weaknesses he noted: 1. While the stated accuracy sounds nice (.1mm), it really isn't all that good. It'll result in noticeable surface imperfections and stair stepping artifacts as the machine lays down the layers. He went on to say that round or curved objects would fare even worse. 2. Given the above he also said it's worth mentioning that it's very difficult to do any post processing of the prototype. What this means is that the material does not respond well to finishing techniques like sanding, sculpting, etc. 3. The results of the printing process are not permanent or particularly durable. While some bonding between the layers of material certainly takes place it doesn't hold up in the long run under use. So what all that really means is that this thing sort of "is what it is" and if any of us had hopes of producing permanent parts with it (like knobs, enclosures, whatever) it'd be a bad idea. Report

Interesting. On one of the videos the guy had prototyped some gears etc and I thought it was pretty awesome. I assumed the layer-layer bonding was pretty good after the example of the foosball guy etc. All thing above stated I still want one. I showed my wife and her response was: that's cool. Now I just need to bide my time.... Report
January 22, 201016 yr comment_317943 I've used a couple of 3-D printers back at the university, last time about two years ago, and only one was good enough to use for anything that I would think of as being a finished product on certain things. From what little I know, that one in particular was most definitely not cheap. Report
January 23, 201016 yr comment_318163 Could you not: Make 3D prototype,Make a mold of prototyped articleCast article in more durable material, using prototype mould.Finish cast article? Thus not be limited by properties of prototyping material? E.g prototype fancy case / heatsink in 3D CAD programPrint 3d prototypeMake mould of prototypeCast metal into mouldShotblast / powdercoat resulting itemProfit! Report
January 23, 201016 yr comment_318167 Could you not use the design files and a professional service to make a finished product without the prototyping process and also with none of the flaws of the prototype for cheaper? I don't think the prototyping material would make for a very quality mold either. I wouldn't want to pay to make a mold to make only a few cases, as usually the mold will cost more I would think to produce. Report
January 23, 201016 yr comment_318403 What if I want aliasing? I'm sure you don't mind them all the same color either. Report
