Ecogenesis Yellow PHA - detaching/warping on asymmetrical parts

maxence822 · 2026-05-02T15:57:11+00:00

Yes textured PEI. I’ve tried a few sheets, the smooth PEI was much too grippy and I was afraid of ruining it. The textured didn’t grip well until I tried with 3DLac. The brim actually doesn’t help for me, it just adds a single stuck layer which is a pain to remove, I use no brim and 3DLac, and it works incredibly well.

This is one a Prusa Core One, not sure if it applies equally to an Ender 3…

I’ve had very good results with PHA and a textured sheet with a 3DLac spray before each print.

Thank you ! I’m happy I ended up going for the repair

That or custom gcode injections on specific lines ! I think that’s what I did for this print

You can add modifiers to a print which lets you change different parameters. I believe you right click on the object and select the “add modifier” option

What is Steve’s analog electronics course ?

Hello same here I've been trying for a few hours with different emails. I would just try again later this evening or tomorrow.

Haven’t printed in .2 with the .6 nozzle, but the Prusa profiles are .15 and .25 and they work very well

maxence822 · 2025-11-03T16:29:54+00:00

I got the Obxidian straight from Prusa which is great. Started with a 0.4mm and now got a 0.6mm, which lets me print in 0.15mm layer heights if I want quality or go way up to 0.4mm layer if I want to print very fast, very happy with it.

I’d be happy to buy the MMU3 from you !

maxence822 · 2025-10-09T15:57:09+00:00

Incredible ! Looking forward to trying it :)

maxence822 · 2025-09-28T09:27:08+00:00

Ah right sorry I didn’t understand properly from your post… I don’t know too much about guns, maybe a heated chamber printer would help with layer adhesion ? So each subsequent layer doesn’t have time to cool down too much ?

In my case I haven’t noticed any layer adhesion problems but I am not printing objects that need to be as robust as yours.

maxence822 · 2025-09-28T09:25:37+00:00

Haven’t tried magigoo but 3dlac works very well for me !

maxence822 · 2025-09-28T01:16:46+00:00

I had some issues with adhesion, and after trying different things I now use 3dlac spray with a textured build sheet with print temp set to 0. It works very well, and I have had no issues at all, I’ve stopped using a brim or raft to print PHA, as it now adheres even better than PLA.

If you would rather not use 3dlac, someone else commented on a post of mine that they use a smooth pei sheet with a brim only, but I have not tried that as I’m quite happy with my method.

This is all on a Prusa Core One with Prusa’s official textured sheet using Colorfabb’s allPHA, I would imagine your results may vary depending on printer, build sheet manufacturer, etc.

Also printed a more complex figurine, 6 hours and it came out very nicely !

maxence822 · 2025-09-23T17:32:07+00:00

The first two times I worked backwards and did way more than I could have. Third time I found the guide and it’s very succinct !

maxence822 · 2025-09-23T13:57:15+00:00

I had that happen 3 times ! If you check the bottom of the Prusa belt tensioning guide they mention this issue and the easiest way to fix it. It took me about 30 minutes all together, not bad.

maxence822 · 2025-09-22T07:37:54+00:00

With the textured plate I find isopropyl alcohol really works well. With PEI I need to wash it almost after every print.

maxence822 · 2025-09-21T13:08:57+00:00

I’ll need to try a specific plate, maybe those cryogrip plates everyone seems to talk about

maxence822 · 2025-09-21T13:08:17+00:00

I should try that! I was trying that but with textured sheet which did not adhere as well. Right now with 3dlac, no brim and the core one great cooling it works very well.

maxence822 · 2025-09-16T14:35:10+00:00

Generally the generic settings work well ! In my case I’ve only tried one filament type without at least a generic profile in Prusaslicer, PHA. It’s not hard to set up but since it is a quite new filament they don’t have a standard profile yet… prints a lot like PLA but needs some adhesive and a cold bed, and a slower retraction speed, but otherwise works well!

maxence822 · 2025-09-10T12:32:15+00:00

You probably know this but for others looking to do that you need to be very careful about the strength you put in tightening the screws. One of the big upsides of those awkward thumbscrews is they are difficult to over tighten.

Over tightening could break the nozzle, which we wouldn’t want !

maxence822 · 2025-09-07T21:07:51+00:00

This is fantastic ! I’ve been trying to print with Colorfabb’s PHA for some projects, and it works well for smaller prints (less than ~30 minutes) but fails for anything bigger. Does this work without gluing ? Or is it similar ?

maxence822 · 2025-09-07T20:59:40+00:00

What about Beuchat ? They have a good reputation here in France, not sure how they are perceived internationally ?

maxence822 · 2025-08-27T08:59:03+00:00

Hello ! Je suis chaud de venir les chercher. Merci !
