ABS?

[Phil Green]

Complete printing numpty three weeks into a Creality K1 here, with a question for the experts please 🙂

The original support wheels on the lower tray of my dishwasher have worn to the point the tray catches on the whirly thing below.

All I have is Creality Hyper PLA and the new wheels solved the problem but as I half expected, they melted in a 60° wash.  So the question is, would ABS survive?  If not, what other options might?

Ta v much 🙂

Should be OK up to approx 85°

Beware the fumes....... which I believe are nasty

Not nasty at all GG - in fact barely noticeable. I print ABS in an enclosure and you don't even know it's printing until you open the enclosure, just a matter of giving it a few seconds for the warm contaminated air to disperse. It's nowhere near the level of fumes of say hot wire cutting a foam wing.

Happy to be corrected 🙂

I sidestepped ABS in my printing and went with ASA which is meant to be superior to ABS and less smelly, but you still need the high temperature hot end and bed and ideally something to avoid draughts, I surround my printer with 2mm MDF sheet.

 

Oozenest sell 50g samples of a lot of filaments, OK extra cost /gram but saves you buying a full reel for a small item.

Just to round this off, the ABS wheels have completely fixed the problem, they've been in there a month now and no distortion at all 😃

I used ABS for electric motor mounts on my helicopter conversions, after PLA softened from the heat of the motor. It worked, but was brittle and prone to fracturing. I switched to PETg, which has a similar temperature threshold but is less brittle. So far, so good!

Pete - I found the same with some spinners that I printed recently. Following sound advice, much appreciated, from Paul Johnson the PETG spinners were much more robust and stronger, with no sign of delamination. It certainly pays to be able to switch filaments to suit the jobs. I find ABS the nicest plastic to work with for non load bearing parts - it sands well, glues together beautifully with styrene solvent and carves to fit much easier than the tough PETG or even PLA.
