    Default Be careful what you don't wish for

    Pete F would probably find this amusing as he and I used to disagree over some aspects of 3D printing, but work recently took over another company and so gained a 3D filament printer. It's a biggish one (300x250x520mm envelope) and gets hot enough to print nylon. Through some strange twist of fate, I'm the only one in the office with suitable CAD software to drive it.
    Trouble is, I can't think of anything to print with it (for home that is).
    Today I tried printing something with threads in it to see how it handled it.

    It's a lathe tool that I'm thinking of making so I can use 1/4" HSS more easily (the goal is to use the same insert to cut both internal and external threads - should improve fit?). The grub screw holes came out reasonably well although under size. Sometime soon I'm going to make a metal version. I'm currently debating whether to try the nylon version out. It might last for a little bit...

    Michael a mate use to work at a plastics injection company if this was made from similar plastic I have some samples of it would not flex OR from the Carbon Fibre plus other stuff mixed with it they use to machine it afterwards and produce sparks.
    Would be interesting to know how it goes.
    How about an Dremel grind attachment that fits the tool post? OR a Dremel Mini Mill to fit the tool post

    There are a couple of things I'm trying to resist the urge to buy, a Drone and a 3D printer. However I can see myself with a 3D printer some time in the future. They are very handy things to have sitting in the corner. That's pretty cool to have access to one at work and be the only person who can use it!

    Girl, I don't wanna know about your mild-mannered alter ego or anything like that." I mean, you tell me you're, uh, super-mega-ultra-lightning babe? That's all right with me. I'm good. I'm good.

    I'd love a 3D printer if I get into casting.... imagine being able to print your patterns and your ready to go.

    Hmm... how much trouble would it be to draw and print a replacement helical power feed gear? Wodonga men's shed haven't had any luck finding a replacement, the pack of 5 I ordered were no good on the OD, actually, I still have them and could machine them down and glue a new gear ring in place and save a lot of plastic..

    Was in at the men's shed the other day and saw their 3D printer, purchased nearly two years ago, still gathering dust in a corner. The member who organised the purchase (ex TAFE computer Guru) who set it up, and ran a couple of training sessions, is a bit like me and doesn't go into the shed that often. Since then I believe said member has used it a couple of times and one member has printed one with it. Same goes for a bunch of Arbortech gear that one member was keen to get (he already has the gear at home) - no one hardly uses it. There's also a near new mill and a lathe out there collecting dust because the member who brought these into the shed was really the only member skilled enough to use them. Unfortunately he is now too crook to attend so they are not being used. If members want to turn a bit of metal they are happy enough to use the old Qualos and for small milling jobs they use the Drill Mill.

    I have 3 3d printers, After lots of messing around i have been able to get 1 print out of each of them, then i can never get a successful print out of them again.

    I'd prefer to cut the thing old school. I think for a power transmission gear, a printed one would not last long.
