      Frequently Asked Questions

      What is the difference between Ultrafuse PA and TPU?
      Ultrafuse PA prints at 240°C nozzle / 70°C bed (No enclosure, low moisture sensitivity). TPU prints at 200-240°C nozzle / 30-60°C bed (No enclosure, high moisture sensitivity).
      Is Ultrafuse PA or TPU stronger?
      Our dataset does not include comparable tensile strength values for both. Qualitatively, Ultrafuse PA is suited to , while TPU is suited to excellent layer adhesion.
      Which prints at a higher temperature, Ultrafuse PA or TPU?
      Ultrafuse PA prints at a higher temperature (240°C nozzle vs 200-240°C for TPU).
      Is Ultrafuse PA or TPU better for beginners?
      Ultrafuse PA is better for beginners: enclosure is no and moisture sensitivity is low, vs no enclosure and high moisture for TPU.
      Should I use Ultrafuse PA or TPU for flexible parts?
      For flexible parts, TPU is usually the better fit (Excellent layer adhesion). Choose Ultrafuse PA instead when .
