3D printing parts and materials help

[lordjasper1988]

So me and my dad are on the road to get a 3D printer and I'm hoping to make some parts... I know they're not gunna be as strong as milled aluminium but I'm hoping to make a basic car using axial drive line parts. What materials would be good to use? I know nylon is tough and I know I'm a long way off but any help would be appreciated.

I moved your thread to a more appropriate section.

This thread should help you some: http://www.rccrawler.com/forum/tool...t-material-3d-printing-transmission-part.html

Consumer 3D printers aren't good enough for big structural components, in my experience. You won't be able to print nylon, at most ABS, and big parts using ABS are a royal pain. I use 3D printing for body details, interiors, small structural parts (replacing original plastic parts, not metal), things like that. Some people 3D print full bodies

I was thinking of using abs for the body, but thanks for the advice! Appreciate it!

I don't think it'll work, ABS tends to warp, and the bigger the part the worse it gets. PLA is probably the best bet for a full body.

Thanks man! Looking back, the abs bodies are probably cast in a mold... Unless I make them modular! Like an airfix kit! Would that make them less susceptible to warping?

Consumer printers are just fine in size for RC parts and some can even do bodies.

PETG is a better alternative to ABS IMO.

Thanks @JatoTheRipper!

Yeah hardbodies are injection molded which is a completely different deal. I know a lot of people do 3D printed bodies in chunks and then assemble them. But even in chunks ABS will still warp.

OK mate, thanks for the advice!

With what printer do you print ?8)

You won't be able to print nylon

Are you trying to say that printing nylon is impossible or just recommending against using it to someone new to 3D printing? It is absolutely possible, it just isn't the most friendly material to work with.

You need a hotend going over 250C for nylon. Out of the box the printer won't print nylon. Better?

I have the Prusa i3 MK3S and Monoprice Select Mini

Your printer may not do 250C, but there are definitely printers that will print nylon out of the box.

Yeah, there are also printers that can print sintered metal out of the box. What's your point? Seriously the internet is stupid. #notall3dprinters

Guys can we not argue please?

No, what's your point? You were wrong. You've continued to spread false information on this thread. You obviously don't know much about 3D printing so I highly suggest nobody take your advice in this area.

No arguing here. I'm just trying to stop somebody from spreading false information which can confuse people new to 3D printing.

 

[lordjasper1988]

If you guys aren't gunna calm down I'll just kill the thread. I understand one of you is a mod but this is my thread. I'm not having you two f**k it up. You wanna argue DM each other, don't do it on my thread.

Give advantages and disadvantages of your suggestions. Then anyone reading can make their own mind up, we're supposed to be helping each other!!

I'll let you two guys exchange false information. I tried to help and you don't want it so good luck. "thumbsup"

To be successful, you really need to educate your self about the materials and techniques used in 3-printing. I would start out by looking at the ALL3DP 2020 Materials Buyers Guide.
https://all3dp.com/1/3d-printer-filament-types-3d-printing-3d-filament/#exotic

I would also check out the Spring 2020 Best 3D Printer list.
https://all3dp.com/1/best-3d-printer-reviews-top-3d-printers-home-3-d-printer-3d/

You should see if that are any maker spaces close to where you live. It is nice to have someone local to get help from.

After that I would watch Maker's Muse: 5 3D Printing Mistakes you WILL make - and how to avoid them! https://youtu.be/aWg1nG2AbA8
(Angus should add "Biting the hand of the guy that was helping you to the list.)
