3D Printed Parts Thread

What’s your chip load? Looks like some FPT and possibly some sort of tool helix angle causing too much chip thinning. Kinda stringing out and welding chip back to work piece. I had similar issues with my haas desktop. We ran a bunch of comparisons and found that with delrin, we had to run higher fpt, so dropped spindle speeds for a given feed rate, also had to thin in inside corners. For aluminum, there were multiple things that had to happen, most notably finding a good helix angle for tools, and ratio of doc/engagement/fpt/sound pocket.

This was a couple years ago so im not sure.

The 3018 was designed to be an engraving machine so I was already pushing its limits.

I just remember using a short 1/4” 3 flute endmill because that’s all I had at the time. I adjusted the SFM till there was less chatter and then ran it.

Now if I had a proper machine, it would be a different story. I machined this same part on a VF-4 at my job in 6061 and it came out nice.

Printed in eSun ABS. My first time trying ABS and it went great. I enclosed my printer with cardboard and shipping materials held together with tape and had no issues with warping or adhesion. In fact these things were REALLY stuck to the build plate.

Hell yeah! Came out nice.
Glad to see my parts being used.

I haven’t experimented with ABS but I’ve been messing with ASA on my new printer. It’s basically a UV Resistant ABS that’s easier to print.

I got a crazy good deal on a Einstar 3d scanner. So now 3D scanning can resume at home. In between Baldur's Gate 3. Armored Core 6. Starfield. Forza 8. It's a TOUGH time to be productive.
Sick, I've been wanting one. I've been thinking about diy 240 adjustable front control arms and a 3d scan of the frame slash mounting points would be real handy.

Also I bought a roll of petg and haven't been able to make it print decently. I got abs and asa working fine, I thought petg was supposed to be easier.

PETG is one of the harder filaments to work with.
It likes to stick to the nozzle.
Ive recently bought a roll of carbon fiber reinforced PETG and its a lot easier to print and has a better surface finish.

ASA has been my go to for final parts though
 
I just bought some upgrades to my Cr-10. I have never printed in ASA but would like to give it a try. Any tips?

You need to have a enclosed printer to print ABS/ASA. Any wind draft will encourage warping.

An all metal hotend is also required due to the higher nozzle temp.
I would also suggest a PEI build plate and Magigoo adhesize for first layer adhesion.

You should be good using a generic printing profile for ABS/ASA but keep in mind that fan speed is important.
More cooling helps with surface finish on overhangs and bridges but also can make the parts brittle.
 
Cool thanks for the info. I have my printer fully enclosed already with the PEI build plate. I will look into the Magigoo for the first layer adhesion.
 
cadded up the rear seatbelt covers for the 242/244 cause I'm cheap and $60 is too much.


I plan on making more stuff later. Does anybody have cad or good pictures of the exterior trim? Cross-section type view would be nice.

Damn your running a 1mm nozzle on your printer?

Do you have any pictures of your prints?
I didnt know they made nozzles that big.

Yeah it can be kind of a pain to print with sometimes but these printed in about 4 or 5 hours each. Overall print quality isn't a huge concern for me especially with a bit of acetone smoothing.
Here's some pictures. Don't mind the messed up covering in the back. I also plan on painting them.
