Dishwasher-safe PLA is designed to survive trips to the top shelf of the washing machine. More thermal resistance.

Why is this PLA not suitable for RC models? Anyone tried?

Raptor PLA

Mine has not had warm enough weather to TEST yet.

I will also be looking forward to testing PET-G prints ...

When/If it ever warms up again ! :>{ it's currently 12 deg F here

I had not heard of ASA. that is interesting... a test must be done... specifically if at similar weights is as rigid as PLA?

Incredible print quality: ASA from rigid.ink is ready to replace ABS! #Filaween (1 min 51 sec)

Seems to be doing well so far inside a foamboard box.

I think I read that PC will block radio waves. So you may need to make sure that your rx antenna is outside of the fuse...

Polycarbonate does not block radio waves. https://www.integraenclosures.com/ne...lications.html

I did ask the shop selling HT-PLA if it behaves any different without annealing it afterwards.
I was told it will get soft at 80 deg C instead of th usual 60 deg C of regular PLA.

If this is true it would be helpful. I have printed three hull pieces of the Mig so far. It prints exceptionally well. I just hope the plane wont desintegrate at the very first sight of the sun.
I might attempt a plane out of PETG after this.

Well that is good. I wonder what I was thinking? Carbon Fibre?

Yeah, carbon fiber will block RF, poly carbonate probably does nothing. It did have some really weird print artifacts. Gonna have to do another after sealing up my foamboard enclosure a bit more. It only got to 80 degrees Fahrenheit inside it.

Probably depends on the brand of heat treatable / high temp PLA used, but the results in this video are concerning on that front.

What's the temperature resistance of annealed PLA, PETG and ABS? (11 min 34 sec)


He tests a bunch of different stuff, and while the two HT-PLA brands he tried did better than the rest after heat treating, if they weren't treated, they softened sooner than normal PLA.

However Poly carbonate will protect from Tritanium which is radio active....

Win win really.......

Can you tell us more of what you think of the poly carbonate filament?

I have used some 3/4 inch foam board insulation I got from Lowe's. Basically it is styrofoam with a foil covering. I have gotten my enclosure to 50 C with only the printer running inside..

That is concerning indeed. I shall find out one way or another.

I have tried PETG+Carbon: https://www.filament-abs.fr/produit/...rbone-optimus/
After printing it has a density of ~1.05, which is about 20 - 25% lighter than PLA. Offers very good layer bonding and stiffness.
Also tried a PETG+Kevlar, which is even bit lighter. Both of them warp as little as PLA.
There are several on the market, watch for density in the technical data.
Important: Keep printing temp on the higher side, keep extruder flow slow. If extruder flow/printing speed is too high, layer bonding suffers significantly.

The best filament I tried is this one: http://www.eumakers.com/de/nylon-carbon-fiber.html
Nylon+Carbon. After printing is has a density of 0,8, and outperforms all PETG and PLA regarding layerbond and durability.
However, nylon is not easy to glue. Most probably this particular one is a Polyamid 12 (one of the lightest plastics) and therefore even worse to glue.
This Nylon+Carbon warps a bit more, I could print fuselage sections, a wing sections with 18cm length lifted its ends about 1 mm.

Simplify3d just put this out ...

Since my 3dPrinter is in the HOUSE,

ASA is now pretty much a MOOT POINT !
