Specimen print settings are not stated; recommended processing on the sheet: nozzle 240-260 °C, bed 100-120 °C, 40-80 mm/s. Product is discontinued (Forward AM product page) but the TDS is still served by Forward AM.BASF Ultradur B 4300 G6 (PBT, 30% glass fibre), injection moulding grade; product information sheet 09/2026, typical values for uncoloured product at 23 °C.

Every value links to the document that states it. "Not sourced" means no citable source states it (or only a specification minimum); figures computed from it are left out too.

FDM HIPS is 3D printed: its properties depend on build direction and print settings; these are typical values.

Questions

Is FDM HIPS stronger than Plastic PBT GF30?

Plastic PBT GF30 is stronger: its tensile strength is 140 MPa against 18.4 MPa for FDM HIPS (7.61x).

Which is lighter, FDM HIPS or Plastic PBT GF30?

FDM HIPS is lighter: 1,023 kg/m³ against 1,530 kg/m³ for Plastic PBT GF30.

Which is stiffer, FDM HIPS or Plastic PBT GF30?

Plastic PBT GF30 is stiffer: Young's modulus 9.8 GPa against 1.59 GPa for FDM HIPS, so the same part in Plastic PBT GF30 deflects less under the same load.

Which is lighter for the same job, FDM HIPS or Plastic PBT GF30?

For the same stiffness or strength: Plastic PBT GF30 is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate, strong rod or tie, strong beam, strong panel or plate.

Part that must beFDM HIPSPlastic PBT GF30
Stiff rod or tie (tension)4.13x heavierlighter
Stiff beam (bending)1.66x heavierlighter
Stiff panel or plate23% heavierlighter
Strong rod or tie5.09x heavierlighter
Strong beam2.59x heavierlighter
Strong panel or plate1.84x heavierlighter

For the same stiffness or strength, mass scales with density over stiffness (or strength) raised to a power set by how the part is loaded: 1 for a rod in tension, 1/2 for a beam in bending, 1/3 for a panel (the standard material-selection indices).

Which handles higher temperatures, FDM HIPS or Plastic PBT GF30?

Plastic PBT GF30 does: 205 °C against 86 °C for FDM HIPS, both HDT 1.8 MPa.

Which conducts heat better, FDM HIPS or Plastic PBT GF30?

Plastic PBT GF30 conducts heat better: 0.27 W/m·K against 0.17 W/m·K for FDM HIPS.

Which expands less with temperature?

Plastic PBT GF30 expands less: 25 µm/m·K against 80 µm/m·K for FDM HIPS.
