I know a guy who owns a powder printer, as well as a bunch of plastic printers. so yes, they're real. Not only that, there was a thread about this same video here last week. does he do commercial work? I've been trying to get some contact info from one of the companies that makes the machine. I need a few parts from a specific material, but the company wants me to buy the whole damn machine. Posted Via AR15.Com Mobile |
| he rents it out for DIY'ers to use. Metrix Create Space in Seattle. I know he's done commercial work on the laser cutter before, but I don't know if he does on the 3d printers. Contact info is on the webpage, his name is Matt. |

Very real, but the company in the vid "Z" something rapes you on the print media cartridges.
Look for Rep Rap or other lower cost versions you can use at home or 3D Systemd that just bought out Alibre. It is common to acutally 3D print a complete intake manifold to fit up for dyno testing to see how changes affect HP before a design gets finalized. I have started building a "Prusa" Mendal rep rap.

We got one of those Z510 printers. The print heads are HP45's or something. Note that thats printheads, not ink cartridges, but there is ink in em, and they get purged anyway so the special binder can go through them. The material we use, Z130, is $2200 for a 80# drum, $150 for the 1/2 gal color binders, and I think $200/gal for the clear binder.
Now it's a boat anchor for us, cause the company now prefers to use a FDM (fusion deposition machine), which puts down layers of plastic material. The zcorp put them down at about .004", while the FDM is much thicker, I don't know how much, but curved parts are very much more noticable. Expensive stuff, I will tell you up front. |

Bookmarked. |

Bookmarked. there's a guy working at mcs on a kit which, with a set of molded parts, will give you a complete clonedel for under $200, motors, computing, and all. don't know if he'll see it through to completion, but I wish him well. |

Polymer receiver, anyone? Not strong enough material yet. Give it another 10-20 years though, then we'll be talking. Can you imagine the ATF head explosions if we could do that? There are RP materials that are essentially sintered bronze/steel mixtures. They aren't anywhere near as tough as a heterogeneous metal, or even some plastics, but probably adequate for a lower receiver. It'd be incredibly expensive though. There are a lot of various rapid prototyping techniques, mostly differing in the materials and precision possible. I've been a big fan of fuse dep. types, since they can use the same plastic materials that my former job worked in. I could, in a matter of a few days get a fairly good prototype of an injection molded part without having to make a mold. It would have a lot of the same physical properties of the molded part (so locking tabs, screw bosses etc. all work right) and, with some finishing work, I could get the basic look and feel of the real part. |

real. it builds up layer by layer with a binder in powder. |

http://www.redeyeondemand.com/ is a good source for FDM and STL prototypes. I use them with work on a regular basis. |

The Z-Corp parts are not nearly as good as SLA, SLS, or DMLS. The video shows them just scanning a wrench and then pulling it out of the printer. That aspect of the video is bullshit, they didn’t show a lot of steps in between. |

I like the fact that FDM uses a thread of ABS to build parts, but the tolerances are poor. FDM is built .005” per pass, versus .0005” for high-resolution SLA. |

I just got a flyer from one of the machine vendors that they have a new material out. I need to make custom supports that can tolerate exposure to about 300 degC and either not produce, or quickly drain built-up static charge. Basically, what I need to know first is can you do it cheaper than milling it out of aluminum? PM me if you're interested, and I'll send a request for quote over when I get to work. |

After reviewing what random disorganized info I found the answer is a definate NO. I already have a CNC Mill, and have the Metal Mendal print set - but the guy who did that went totally anal in trying to make it like a Swiss watch vrs a Honda car. I readily admit the layered look of printed PLA or ABS is somewhat crude - I have outsourced STL / SLA work when the job needed the finer resolutions. |
