3D Printing For Everyone 183

mmacx writes "Technology Review has up an article about Shapeways, a new online rapid-prototyping service that allows users to upload digital designs which are then printed on 3-D printers and shipped back. A spinoff from Philips Research, the service gives small businesses, designers, artists, and hobbyists access to prototyping tools that were once available only to the largest corporations. The fee for a typical printed object is $50-$150. Their video shows the steps behind the process." We've been talking about 3D printing for years.

    Every time 3-D printing comes up I like to consider what this will do to my favorite hobby, model-building...

    Styrene injection kits have been around for ages, and they're generally the cheapest way to get a kit made in large quantity - but because it costs so much to set up the molds, usually they're pretty hesitant to make a kit of anything that's not a pretty sure-fire seller... Additionally the hobby has been dying by inches for a long time.

    To fill all the niches of interesting subjects that nobody's bothered to make injection kits of (this would be, for instance, things like the Serenity cargo ship) there's resin kits - but because of the high degree of manual labor involved in casting the parts, as well as the material expenses and the initial sculpting work divided over a run of maybe a couple hundred kits, they're pretty expensive for the person buying the kit...

    But then you think about stuff going on these days, like papercraft - people making model designs, putting them online in a form that other people can print out and build dirt-cheap. The results aren't generally as good as injection or resin models but it's quite impressive, and inspiring what they've accomplished...

    So it's fun to think about what fabrication could mean for the hobby. On the one hand it may actually mean less people buying and building models, or scratch-building parts themselves. Rather, once the technology is cheap enough, more things will be simply fabricated. But on the other hand - to think of something that would today be a garage kit, only done up as a downloadable design for fabrication... that would be pretty damn cool.

        I'm a member at the TechShop, and they have a 3D printer from Stratasys. It prints in ABS, what Lego is made of, but it doesn't yield Lego-like parts. First, resolution is limited because it feeds small diameter ABS rod from spools and fuses it together -- imagine printing in 3D with weed-whacker cord and you have a good mental picture. Secondly, it is not as strong because it has lots of heat-fused joints and also not all ABS is created equal. You can dip your resulting part in acetone and get the whol

      Traditionally, creating the design has been done in hardware (a master, which is used to produce moulds etc.).
      With a 3D printer, you can either build a master, scan it and clean up the data, or you can build the model in CAD. CAD is less messy, but I'm not convinced it's faster than building a master.

      Not sure on the open source software front but i've always been fond of Rhinoceros 3D for doing modeling since it is relatively in-expensive to buy a commercial copy ($900).

      You can send your 3-D file to lots of companies, i'm not sure why ShapeWays is getting all the press when there are thousands of RP companies called "service bureaus" that will take 3-D models you upload and print them using some RP machine then ship them to you, usually with a 1-2 day turn-around time.

      I used to get some parts done with http://www.rjmrp.com/ [rjmrp.com] but they focus mainly on high-resolution small parts (such as jewelry pieces). So, if you're designing jewelry i'd recommend them otherwise look for some other companies using Stratasys type machines (there are lots). The costs they quote sound about normal, typical jewelry prototypes were around $100 or so for a ring in .001" resolution.

      While this is a really cool service, nothing can beat hands on. My preference is The Techshop [techshop.ws].

      The site seems slashdotted already. Google's cache should have a copy of their 3D printer, laser etcher, and other services for building (nearly) anything that you can imagine.

      This is the most innovative thing to hit Silicon Valley in years. It really should've been covered by Slashdot long ago.

      The advantage the Techshop has over mail-in is that you can get advice on how to create your prototype. The costs for a 3D print job can vary greatly depending on how you do it. Just the orientation alone can either save you or cost you quite a bit. So that's why I prefer "hands on". Now, if I really knew what I was doing, or I didn't have a TechShop nearby, then I'd probably do a mail-order service.

      As far as apps goes, you can pull down one of the Google apps (whose name I've forgotten at the moment) and use that.

      Oh - and the guy who founded the TechShop used to work with Mythbusters in creating their gadgets. I hear they even showed up on opening day.

    I can see one stumbling block for 3D printing becoming more popular: the software you need to create a 3D model is generally expensive and difficult to use.
    Google Sketchup is a potential answer here, but the last time I checked, the 3D printing house I wanted to use didn't accept Sketchup files (and/or the free version of Sketchup doesn't allow export to any generic 3D format).

    • Microsoft made caligari truespace available for free.
    • Sketchup Pro is $495 and allows CAD export.

      Yea thats expensive but if you Really need this for your work, its cheap.
