The bars show the share of the highest value in each column. They appear only on the four figures where more also means more performance; density and elongation deliberately carry none.

The comparison covers the filaments. The two resins are not in the table: their figures are not directly comparable with those of a filament.

What I print with

Six manufacturers, chosen by material.

Not by price, and not all from one source: the strengths differ by material, and I pick the manufacturer to match. Which one is right for your part, I tell you with the quote.

  • standard materials and the carbon-filled range

  • tight diameter tolerance, every spool measured

  • larger quantities, where colour matters more than the data sheet

  • PETG and polyamide, where it has to carry load

  • European production, matte surfaces

  • specialty materials and colour consistency across batches

Why Printerking

Checked before it is printed

Every file goes through a technical review: wall thicknesses, load direction, fits and tolerances. If a different material carries the load better, I say so before the quote.
