Glowforge is a CNC Laser Cutter, not a 3D Printer (Video)

Co-Founder and CEO Dan Shapiro says, right at the beginning of the interview, that the Glowforge machine is a CNC laser cutter and engraver, not a 3-D Printer. He says they've "simplified the heck" out of the hardware and software, and are making an easy-to-use, non-costly ($2500 has been bandied about as the unit's likely price) device that can fit on a kitchen table -- or, more likely, a workbench at a maker facility. Although Dan did very well on Kickstarter (and afterwards) with his previous venture, Robot Turtles, this time he seems to have raised his first $9 million in the venture capital market, with participation from several MakerBot executives.

Glowforge is not the only CNC laser cutter/etcher device out there (or about to be). In Australia, Darkly Labs appears to have raised $569,397 (AUD) on Kickstarter to bring their LazerBlade to life, and already makes a small laser device called the Emblaser. There are others, too, including Boxzy, which did the Kickstarter thing and will now sell you a device that "rapidly transforms into 3 kinds of machines: CNC Mill, 3D Printer & Laser Engraver while enhancing precision & power with ballscrews." All this, and their top-of-the-line "does everything" machine sells for a mere $3500. Obviously, devices to give makers and prototypers the ability to make ever more complex and accurate shapes are coming to market like crazy. We'll continue to keep an eye on all this activity, including a second video interview with Glowforge's Dan Shapiro tomorrow.

      One could argue that an inkjet printer is thus a CNC extruder, then. Where does it end? We make up words to usefully cover categories and describe concepts, and sometimes those categories and concepts overlap. "CNC", "extruder" ,and "milling machine", are just too generic to be used in some cases, and too specific to cover the wide variety of CNC additive manufacturing devices, so "3D printer" was added to the mix to specifically cover all slice-based additive manufacturing devices, whether they be extruder, glued powder, film exposure, or sintering based (and possibly other types).

      So, there are machines that are both CNC extruders and 3D printers, but not all CNC extruders are 3D printers, and not all 3D printers are CNC extruders.

      Also note that a CNC laser is not a CNC milling machine. In fact, the CNC milling machine owners get huffy if you call a CNC router a "CNC milling machine". Perhaps the phrase you were looking for is "CNC subtractive manufacturing device" ?

    4. Re:frost by Anonymous Coward · · Score: 0

      The huffiness between CNC router and a CNC milling machine has nothing to do with the CNC (Computer Numerical Control). Routers lack sufficient strengthening of the "neck" holding the cutting bit, and thus are not appropriate for large deltas in the height (and quality) of the cut. A router rarely has more than an inch of vertical travel, and you must feed it rather slowly to avoid the cutting head from drifting due to side pressure on the cutting bit. A milling machine typically has this area (and others that impact the cut) reinforced, and allows for much larger amounts of play in cut positioning. That's why the get bent out of shape, you'll ruin your router trying to use it as a mill, risk breaking your bits (not good since it's rotating at high speed), and get poor quality end products.

      Did I mention the actual size of the cutting/engraving area isn't the quoted 300x200 unless you take out the stupid clamping mechanism?
      Or, the weird non-linearities which happen when you try engrave/cut beyond a 'magic' speed?
      (varies depending on day/job/I Ching)

      Or running Moshidraw > 2012 bricks the thing, albeit recoverably?
      (at least, true for the version of the controller board we have in our machine, 2014 sort of works, but not as reliably)

      I use Moshidraw and one of these things every working day.. really crap software and it has a USB hardware key. You require Moshidraw to talk to the damn controller board on the engraver, they had some sort of primitive printer driver in development, last I tried it, it was pretty piss-poor. So, short of changing out the controller and rolling your own mach3/emc2 compatible interface, you're stuck with the perverse at times mangling of your designs that Moshidraw's import facility gleefully performs.

      Ours is relegated to doing simple things like engraving slate coasters (at which it's actually not too bad) and the other quick and dirty small cutting/engraving jobs that we don't want to tie up the larger engravers with.
