Engadget Experiences the Solidoodle 3 3D Printer

Engadget reports that former MakerBot employee Sam Cervantes has brought to market — or at least to Engadget headquarters in prototype form — a working, cheap(ish) 3D printer from his own company Solidoodle. Originally, the new Solidoodle 3 printer was announced at $500; the price has crept up to $800, but that still sounds like a bargain in the world of home fabrication. Unlike the current MakerBot, it has no built-in card slot, so a computer connection is required for the length of a build.

  1. ABS solid doodles are STRONG. by Ungrounded+Lightning · · Score: 4, Informative

    Saw a makerbot being demonstrated with black ABS plastic at a conference last month. The parts made with it were STRONG. (Replacement components of the print head had been manufactured this way.) Also a sample was being made with internal, hollow, completely enclosed and sealed, honeycomb cells, which made it very light without substantially reducing its strength or dimensional tolerances. Should be ideal for things you need to float. (Try building THAT without a 3-D printer: You'd need to bond two or more pieces together.)

    I understand one of the problems with the makerbot that metal-frame follow-ons like this are trying to address is that the wooden frame flexes and changes size with relative humidity, making tolerances lower than they could be with a metal frame.

    Does anyone know how well ABS works for lost-"wax"-casting originals? Or same question regarding other "hot-glue plastic wires" that could be fed through these machines?

      The general process that includes lost-wax casting is called investment casting, and while it can be done with ABS, it requires the mold to be baked off in a kiln capable of much higher temperatures than with wax. Burning ABS at home probably isn't a good idea either. I'm not sure about how other materials would work.

  2. Flaky technology solving wrong problem by Animats · · Score: 4, Interesting

    The problem with these ABS extruders is not building the frame. The problem is not building a 3-axis positioning system. The problem is that you're welding a hot thing to a cold thing. That's always going to be a marginal operation. Without a better welding process (I've suggested aiming a small laser at the weld point) this will continue to be a flaky technology. I've seen about five versions of this technology in action, and they all sort-of work, but don't yield consistently strong parts.

    The ultraviolet stereolithography technology yields much better part quality, but still costs too much. Formlabs may succeed in getting the cost down to $3500 or so. They're demoing at CES.

    That... Is the stupidest name for a company/product i've heard in a long long time.

    If you object to stupid-but-cute names, why are you on "Slashdot?" B-)

    (I'd have a four-digit, or maybe even a three-digit, i.d. if I'd been able to figure out the URL when first told about the site over the phone.)

    As for "solidoodle" I think the name is great. Mnemonic, descriptive, easy to pronounce, and not TOO hard to get the spelling right. Google search for "solid doodle" (without quotes) spelling-corrects it to solidoodle and finds the company site and discussions about it, too.

  4. Make & Re-use by xeoron · · Score: 4, Interesting

    I wish someone would make a companion 3d printer product that will recycle plastics into the plastic used to print things with some of these 3d printers. If you could turn most any plastic into a strong plastic ink source, then the cost of owning one of these printers goes down and gives people a reason to recycle with a fast gratification of making stuff.

      These exist. There's even a contest to build a reliable, sub-$250 home filament extruder. Filabot used to have the lead, but http://www.3ders.org/articles/20121023-making-a-plastic-filament-extruder.html is also fairly interesting. But none of them seem to be close enough to finalized to actually use in daily life yet. I've heard someone say that it'd be easier/cheaper to just buy loads of plastic pellets rather than dealing with impure plastics from recycled materials. Pellets seem to be about 1/5th to 1/10th the price of good filament.
