    I’m printing 1/2 scale model of my casing tool. For things to fit together I have to increase ODs to match. You’re better off farming it out.

    I'm going to pm you. This is not my area of expertise, either side of it.

    whats the density of that filament? Trying to figure out how much weight we'd save over just machining these out of aluminum.

    PETG is 1.27 g/cm3. Pla and abs are 1.24 and 1.04 respectively

    Don't forget you're probably not going to print them solid... .8-1.2mm walls, rest with a lower level of infill.

    well, that's probably true, but for a first-pass approximation since the density of steel is ~8 and Aluminum is 2.7, if the filament is 1.3, that's a huge enough weight saving to make it worthwhile. I'm working with our shop folks to see what makes sense for us.

    If you have a 3D model you don’t mind sending I can load it in my slicer and give you an actual estimate on time / weight.

    Thanks. I don't have it right now, but will be talking to the machinists and I'll see what we know later today or tomorrow.

    Since it's probably proprietary and they'd rather do in house... What's the windows10 slicer again? There's one in there you could use to ballpark weight. Or download cura.

    Prusa released a cheaper smaller form factor printer. Looks pretty good and aimed to compete with the entry level printers.

    https://www.prusa3d.com/original-prusa-mini/



    - 350USD
    - 7"x7"x7"
    - 32 bit board
    - TMC2209 drivers
    - Same magnetic heatbed style as the MK3s
    - Wifi optional (future upgrade)
    - Ships 90% assembled (3 pieces to put together)

    Kinda looks neat so I ordered a couple to try them out.

    Hey, anyone feel like doing a little project for me? This is for beside my wife's sink, just a couple little filler pieces

    Smooth or minor texture on top, bottom can be whatever honeycomb you want to reduce material. It doesn't have to hold more a couple pounds of weight.
    Piece A size: 22mm high x 100mm wide x 300mm long
    Piece b size: 22mm high x 42mm wide x 150 mm long.

    Pure white or near white preferred. Don't want to paint these, so want the filament color to be appropriate. I pay in either beer or money, whatever your prefer.

    If you have a model I don't mind printing it but I don't really have time to make anything unfortunately.

    Little update on my printing business. Signed a merch deal with one of the biggest DJs in the world, so gotta figure out how to expand my print farm again. Hoping I can run ~8 of the Prusa mini's off one breaker .... kinda pushing it though. Would put me at 14 printers currently running (plus a ultimaker and a formbot sitting on a shelf because pieces of shit)

    You need a printrbelt actually there's a few conveyor build options out there now.

    Digitmakers.ca has the Pallete 2 for 499 with sihpping so ordered one of those. Was going to go MMU2 for the prusa but still hearing a lot of painful experience with it. Hoping the P2 is more reliable.

    Build me one and I'll buy it haha. I just don't have the time or desire to try and scratch build any printers. Pouring the time into product development provides way better returns. Right now with the MK3 farm I can print far more than I'll ever need with one or two times a day popping in to just start the next batches.

    What do you guys think about the Glowforge? Is it just for people to make tacky garbage to sell on Etsy, or is it actually good?

    blackbelt is still around aren't they? Not cheap. But if a box of parts appeared something could be arranged...

    palette 2 has even more frustration than the mmu2 going by the cr10 forums. Same issues but now its not user serviceable...

    No idea on it, although their filter sounds interesting. One of my hurdles of wanting a laser cutter for home use is that I don't have anywhere to vent outside (stupid townhouse rental)

    Tacky garbage for etsy

    Friend has 2 and likes them, beats a k40 on the out of the box performance at least. I'd prefer the k40 with some upgrades myself.
