#htpla on a prusa mk3s+

Has anyone tried other HTPLA filaments from brands like Fusion Filaments or FilaCube, or ProtoPasta. I'm looking to print some stuff that can withstand the heat better. But I've been told it works terribly for prusa printers.

Any tips or better materials to try?

Has anyone had any experience with these filaments?

Any other brands to look for?

How does the annealing process work?

I've been thinking about getting the new E3D hotend with the interchangeable nozzles, would HTPLA work better with that?

Yes, many people have tried HTPLA filaments from various brands including Fusion Filaments, FilaCube, and ProtoPasta. While there have been mixed experiences, it's important to note that compatibility can vary depending on the specific printer model and settings used. Some users have reported difficulties with consistency and clogging when using HTPLA on Prusa printers, but this may not be the case for everyone.

If you're looking for materials that can withstand higher temperatures, you might want to consider trying other filaments like PETG, ABS, or nylon. These materials offer better heat resistance compared to standard PLA.

Regarding annealing, it is a post-processing technique used to improve the heat resistance of certain PLA-based filaments. It involves heating the printed object at a specific temperature for a specific duration to induce molecular changes, resulting in increased strength and temperature tolerance. The exact instructions for annealing can vary depending on t...

It needs to be pla for it's rigidity petg is too flexible and I can't really do any other filaments without an enclosure.

If you can’t do an enclosure but need higher temp you could try PCTG as I found it to be less flexible than PETG, but it prints at 270-280. No enclosure needed though.

#

CF ASA also prints reasonably well open air.

Never heard of pctg

It’s fairly expensive but very strong in my experience

#

Ah I'd rather keep costs low but I'll look into it

#

As for annealing there’s a bunch of different methods

#

Also my printer is in a big room with people walking around

#

All with varying levels of warping

#

If you need the part to be accurate you won’t be able to anneal it

neat pivot
#

This part is made with that in mind

#

It's got support struts that you remove after

#

Then boiling water is one option, salt or sand packing is another and a temp controlled oven

#

Hot plate, water, part in there and bring to 80C then let cool- same way Cnc Kitchen did it

#

They have a couple different videos detailing annealing methods and their effects

#

Oh interesting

#

That's pretty cool

#

But we have a connection oven so that shouldn't be an issue

#

Usual “don’t put printed stuff in the oven” remark

#

Unless it is a dedicated unit

#

Is there some problem with it?

brittle elbow
#

Well, it’s not food

#

And because we can’t be sure it won’t contaminate the oven in any way we don’t recommend using them for filament at all.

#

Food in food devices, filament in filament devices 😛

seems resonable
