High performance material for high performance hardware.

Heated bed and all-metal hotend recommended!

Proto-pasta Polycarbonate-ABS Alloy is an incredibly tough material designed for strong, resilient parts.  Properties are excellent and greatly improved over standard ABS. 

Processing is more challenging.  For best results, a heated bed is required to control warpage and improve layer adhesion.  Cross-sectional area should be minimized.

  • Available in 1.75 mm and 2.85 (3) mm diameters, black or natural color
  • 500g is on a 8″ diameter spool

PC-ABS is moisture sensitive. Even when stored in a bag with desiccant, drying in an oven for ~ 1hr at 85C-95C may be required for bubble free high strength prints.

In our experience, good results are achieved when printing small parts at 270-290C on a heated bed at 110C up to 140C. For larger prints with good layer adhesion and minimal distortion, an enclosure is ideal.

Good stuff I can still print it at 245c

Sadly max I can push my modded Flashforge dreamer with the micro swiss upgrades is up to 245c, surprisingly though I can print at this temp and the pc abs can get loaded in even as low as 225c,

Good stuff, printed well on my Prusa Original

I have only done one print so far, but I was impressed with the material. It has kind of a springy flex to it that felt really nice. Some minor imperfections in the print, but it turned out very well for my first go.

Black PC-ABS is Excellent

I had success with small prints but the big prints I tried all curled even with a heated bed at 125 C. I’m going to try some wolfbite bed adhesion promoter soon and hopefully that helps but it’s tricky on my PEI surface.

PC-ABS Filament

Picked up a roll of Proto-pasta PC-ABS natural at Micro Center for my Fusion 3 F400-S.
All I can say is wow, so I picked up another.
This stuff runs better and produces better quality parts than any material I have tried.
Scarring due to single extruder support is minimal and it separates quite easily.
This is my new go to material for prototypes that don’t require color.
Just ordered two more spools of black.
Well worth the price difference between it and regular ABS.
Only request….. more colors.

Strong and robust. Heat and chemical resilient. An Inexpensive choice for engineering-grade prints.

ABS has solid mechanical properties in the form of heat and impact resistance. Its high durability makes it perfect for printing moving and weight-bearing parts. ABS is shatter resistant; when pushed to its limit parts will bend or warp instead of snapping or shattering. ABS has decent chemical sustainability, making it resilient to sunlight, moisture, acids, and oils. Long exposure to sunlight may cause prints to degrade, making ASA a better choice for outdoor prints.

ABS is quite a common material making it relatively inexpensive whilst also being built to last in tough environments. The main detriment is that it can be quite difficult to print with, and can require printer tuning to get the perfect print.
Printed parts can be polished with acetone, giving them a smooth and glossy finish and hiding layer lines. When printing with this material, it is possible that toxic fumes are produced. This can be circumvented by printing In a well-ventilated area or using an extractor.

Used for: Injection molding, LEGO, electronic casings, automotive parts.
