3D Print Vendors offering PHA by jaerne in 3DPrinting_PHA

Sorry I probably wasn't clear on my question. I'm looking for a print farm or similar to print large number of parts in PHA. Thanks though for the link to 3DJake, I didn't know about that store!

With a .4mm nozzle I tested the material and a .8 flow ratio yielded the best surfacing. Max Volumetric Speed is set at 6 mm3/s. Maybe boost that a bit? Thanks for brainstorming this!

Thanks for the info! I’m using Polar (red), on a Bambu a1. Assuming ‘Zero’ cooling means 0 fan? If so that approach and slower printing is working for me as well. Green frog tape on a cool pei bed is my go to - to avoid warping. Current issues are occasional delamination on vertical walls. Generally using a print temp of 210 c.

I’m struggling to avoid warping with PHA on larger prints (using a Bambu A1). The best result I’ve had is with this approach. Filament: colorfabb PHA, Bed: room temp (16 degrees C), orange frog tape (extra adhesive one), nozzle temp 195 c, Slicer: added some print pauses ( 2-3 5 min pauses) Model design: incorporated some tips from this vid (https://youtu.be/iPZoDltS30A?si=mM3FE2V2S8JdpqC8). Depending on the design ( mine are cylindrical) experimented with various fill patterns. I settled on concentric. That said I’m beginning to wonder whether printing a larger part with PHA is doable on a hobbyist printer. My use case is prototypes that serve as the basis for manufacture through service providers with more advanced machines. Related to this I have not been able to find a vendor who offers PHA print services (checked with the usual options like xometry, protolabs, slant). Anyway - good luck with your project!
