Is Prusament worth the price?

Read the Jet Black page for the precision claim, and read the threads for the shipping complaint. MK4 filament, Overture, Polymaker, budget filament, and storage are the related pages.

The rows

Prusament PLA stores 205–225 °C (401–437 °F), a bed of 40–60 °C (104–140 °F), and a diameter tolerance of 0.05 mm from the Open Filament Database. The Jet Black product page lists a nozzle of 215 °C (419 °F), a heatbed of 50–60 °C (122–140 °F), and ±0.02 mm precision. It also says each batch is checked against a color recipe so a second spool matches. Prusament PETG stores 240–260 °C (464–500 °F), a bed of 70–90 °C (158–194 °F), and a 0.02 mm tolerance from the Open Filament Database, and it links a PETG data sheet. Overture PLA lists 190–220 °C (374–428 °F) and 25–60 °C (77–140 °F). PolyLite PLA lists 190–230 °C (374–446 °F) and 25–60 °C (77–140 °F). Prusament, Polymaker, PLA, and PETG are the indexes.

Shipping and substitutes

r/prusa3d 18wri1j is a high-school order. The poster says a $480 filament order came with $180 shipping to the US. Those amounts are the post. The score-21 comment points at Micro Center Inland and describes it as mostly rebranded eSUN, with some Polymaker and IC3D. The score-19 comment says PLA above about $15 a spool is good enough. The score-17 comment names Atomic Filament.

r/prusa3d 12eowfz asks for a home-printer substitute for Prusament PLA and PETG. The score-25 comment names Printed Solid Jessie at $20–$25/kg in that comment. The score-10 comment names Overture PLA and PETG at about $20–$25 a spool in that comment. The score-9 comment has not tried Prusament because it looked like about double Polymaker. Those prices are the comments. This catalog leaves price blank.

Storage, a bad MK4 surface, and a safety thread

r/prusa3d 16r3koa keeps factory-sealed Prusament and asks how long it lasts at 40–60% room humidity. The score-38 comment says PLA left out for five years still printed. A score-7 comment says the dry box is visibly better. Storage is the guide. Five years is the comment.

r/prusa3d 18sbxc7 is Prusament PLA on an MK4 with a 0.4 mm Obsidian nozzle. The first layer is fine and later layers are not. The score-8 comment calls it slight over-extrusion, with an example of 0.42 mm where 0.4 mm was expected. The score-14 comment says switch back to the stock nozzle. The poster says the spool had eight hours in a dryer. Eight hours is the post. The PLA row does not list a drying time.

r/prusa3d 1ekn24x shows Prusament lab results on carbon-fiber filament. The score-40 comment says technical and safety data sheets outrank a YouTube thumbnail. The carbon-fiber guide is that material.
