A video test by Igor of My Tech Fun compared PC-ABS parts from a Stratasys Fortus 450mc with parts from a Prusa Core One L and a Bambu Lab H2D using Polymaker filament. The industrial parts were more dimensionally accurate, while the home prints looked better, and mechanical differences were mostly small.
Stratasys: 325 C, 95 C chamber, over double the print time
Industrial parts more accurate; home prints better looking
Context PC-ABS is a blend aiming to combine the toughness of polycarbonate with the processability of ABS, and it needs a heated build chamber.
How was the comparison set up?
Parts in Stratasys proprietary PC-ABS were ordered from a company running a Fortus 450mc. Igor printed matching parts in Polymaker PC-ABS on a Prusa Core One L and a Bambu Lab H2D, then tested them in several ways, including to destruction.
What differed in process and results?
Polymaker filament was printed at 280 C in a 60 to 65 C chamber. The Stratasys material ran at 325 C with a 95 C chamber, and the industrial print time was more than double. Industrial parts showed better dimensional accuracy, home prints looked better, and performance differences were mostly minor and not always in favour of the industrial system.
What it means
The test is a single hobbyist comparison, not a qualification study, and it does not replace material data, process control or traceability. For small manufacturers, it suggests that non-critical PC-ABS parts may be feasible on lower-cost machines, while dimensional accuracy and certified documentation remain reasons to use industrial systems.
Frequently asked questions
Which printers were compared?
A Stratasys Fortus 450mc with proprietary PC-ABS against a Prusa Core One L and a Bambu Lab H2D using Polymaker PC-ABS.
What was the main finding?
Industrial parts had better dimensional accuracy and home prints looked better, while mechanical performance differed only slightly.
