Has anyone seen the info about the Scrap 1 Metal 3D printer? It’s not hobby cheap ($14k) but that’s a lot cheaper than the production metal printers. It only has a 4inx4inx4in build volume. With that said, if you needed 20 or more suppressors, it would do well for that. They would have to be a 2-3 pc screw together design in most cases but it’s interesting. That might mean in 2-3 years, we could have a $6-$8k metal 3D printer with a bigger build volume. It’s the second printer in the video below. The first metal 3D printer is kind of hokey.

There was a thread in GD about it last week. One thing to keep in mind with metal printers is that the powder they use is extremely dangerous because it creates an explosive environment. It must be handled and filtered with caution because of the health risks from inhalation. Just FYI for you guys thinking about putting one of these in your basement or attached garage. Also with metal printers you typically need some type of secondary machining operation to separate the part from the build plate. Usually wire EDM in an industrial shop but the home gamer could get by with a cutoff wheel or bandsaw and a Bridgeport to clean up the part, then the build plate itself will need to be reconditioned flat and smooth. Surface grinding is preferred but again a Bridgeport would probably be sufficient. They glossed over all of this in the video but at 9:45 he holds up a part that is still attached to the build plate and they don't talk about how to remove it. Maybe they have come up with a novel solution that eliminates all of that, but I doubt it otherwise they surely would've mentioned it. I'm not trying to put down the printer though just want to keep things in perspective. This is a huge step at scaling down the technology for home use and it's awesome to see it happening. |

He mentions the combustibility issue which is aluminum and titanium. The other metal powders are not an issue. Inconel is what I would be interested in as a hobby printer. I thought they mentioned the post process part but I could be wrong. I need to do more research. |

We have tool steel and stainless powders at work and a filtration system the size of a fridge because either way you don't want to be breathing that stuff. Filtration would definitely be a big concern. A quick google search states aluminum, iconel and titanium can be highly combustible. In his video, he states only aluminum and titanium would be a combustible concern. That kills my iconel printing idea option. Makes it seem like hobby high performance metal powders might not be an option. I will keep hoping they can come up with something that would work. Last thing I need is to blow up my garage/ shop. |
