Toybreaker Posted August 16, 2019 Report Posted August 16, 2019 Anyone use 3d printed pistons or domes for mock up purposes? I am getting ready to fianlly go through my spare engine and have cylinders that need a bore as well as what is "supposed" to be a 4mm crank. Want to mock it up with plastic parts. set it to print a pair of pistons, the models I have set up to run are 6 hours for a high resolution print per pair. Do not want to reinvent the wheel if someone else has already done this.... 1 Quote
97Screamer Posted August 16, 2019 Report Posted August 16, 2019 You better have a very expensive 3D printer. I have printed many parts for mockup on aircraft structures but the tolerances are not tight enough for engine internals. I know there are high end printers that do but those are rare. Why not just measure the crank and cylinders and figure out what you have? Quote

Toybreaker Posted August 16, 2019 Author Report Posted August 16, 2019 Technology is cool, and i have a full machine shop, plus the printers at my disposal. print oversize and machine to dimension if i have to. kinda want to machine a printed sintered metal part anyway Quote

Have a couple printers and lathe/mill/surface grinder/bandsaw at home, have $80k plus in printers and full machine shop at work. Why not? All it is going to cost me is tome and some nylon for the first couple runs.... i have 4 spools of it right now. 1 Quote
97Screamer Posted August 16, 2019 Report Posted August 16, 2019 Sounds like fun. I too do projects just because I can so I get it. Let us know how it works out please.Sent from my HTC One M9 using Tapatalk Quote

Pinkylee Posted August 17, 2019 Report Posted August 17, 2019 Guess I don't understand the usefulness of mocking up engine internals. Unless you are trying to redesign something internally and need to check for interference.😯...are you planning on building your own parts ? Quote

To have an engine to experiment with and try out new designs on. Quote

ClaudeMachining Posted August 17, 2019 Report Posted August 17, 2019 If you are doing it for fun to learn new stuff, go for it, i will help you if i can. Dont know about your 3d printer, but our is about +/- 1/64 (0.015"), precision wise, 3d printer are not accurate. What printing material you will use??? Wich printer ya got??

Toybreaker Posted August 19, 2019 Author Report Posted August 19, 2019 My primary I built. 12"x12"x12" It looks like ass but works beautifully. Lulzbot 18" for the other one. I have access to another 5 that are larger than the ones I have at a local maker space I am a member of.... I might use one of those. the ones at work are HUGE and stratasys. ABS primarily for the stuff I am doing. Quote
ClaudeMachining Posted August 20, 2019 Report Posted August 20, 2019 I use our 3d printer for stuff like this. It help to validate the designEnvoyé de mon SM-G965W en utilisant Tapatalk 1 Quote
Pinkylee Posted August 20, 2019 Report Posted August 20, 2019 Boy.. I wish I had access to one..... I gotta machine everything right from the start..😞 Quote
