What is RGD525 TPT?
RGD525 TPT is RGD525 in the TPT condition — bake the part in a programmed ramp (typ. up to ~90 °C over several hours) to raise HDT for hot-air / hot-water use such as wind-tunnel models. RGD525 TPT has a yield strength of 62 MPa (8.99 ksi) and a tensile strength of 72 MPa (10.4 ksi) — stronger than 72% of polymer grades. Elongation at break is 8% and the elastic modulus is 3.4 GPa (0.486 Msi). RGD525 TPT has a density of 1.18 g/cm³ (0.0424 lb/in³), lighter than 52% of polymer grades. Its glass-transition temperature is 80°C (176 °F). As-Printed is the default condition FabDigit quotes; TPT is available on request or by drawing note.

Working with RGD525 TPT
Is RGD525 easy to machine?
Light drilling, reaming and trimming only — use sharp tools, high speed, low feed and no coolant heat build-up; the crosslinked acrylate chips and cracks around thin sections.
Can RGD525 be welded?
Thermoset — cannot be welded; join with cyanoacrylate, epoxy or acrylic structural adhesive after solvent-free degreasing.
Can RGD525 be formed, bent or molded?
Built only by PolyJet material jetting with soluble/gel support; wall thickness ≥1 mm, keep parts fully supported during the thermal post-treatment bake to prevent sag and warp.
What surface finishes work on RGD525?
Water-jet or NaOH bath support removal, then sand and polish (glossy) or bead-blast (matte); primes and paints readily with acrylic/PU systems — a UV-blocking topcoat is recommended to limit yellowing.

RGD525 TPT — frequently asked
What is RGD525 TPT used for?
RGD525 TPT is typically used for wind tunnel models, hot air flow testing and engineering validation parts. In short: highest-HDT PolyJet resin; hot water test capable; rigid, 75 MPa tensile.
What is the yield strength of RGD525 TPT?
RGD525 TPT has a typical yield strength of 62 MPa (8.99 ksi) and a tensile strength of 72 MPa (10.4 ksi) — stronger than 72% of polymer grades. Strength varies by condition: see the 2 listed tempers.
Is RGD525 TPT easy to machine?
Reasonably — machinability is rated fair (50/100, worse than 73% of polymer grades). Light drilling, reaming and trimming only — use sharp tools, high speed, low feed and no coolant heat build-up; the crosslinked acrylate chips and cracks around thin sections.
Can RGD525 TPT be welded?
Not readily — weldability is rated not recommended (0/100). Thermoset — cannot be welded; join with cyanoacrylate, epoxy or acrylic structural adhesive after solvent-free degreasing.
What surface finishes work on RGD525 TPT?
Water-jet or NaOH bath support removal, then sand and polish (glossy) or bead-blast (matte); primes and paints readily with acrylic/PU systems — a UV-blocking topcoat is recommended to limit yellowing.
Can RGD525 TPT be formed, bent or molded?
Built only by PolyJet material jetting with soluble/gel support; wall thickness ≥1 mm, keep parts fully supported during the thermal post-treatment bake to prevent sag and warp.
What is the maximum service temperature of RGD525 TPT?
RGD525 TPT is rated for continuous use to about 65°C (149 °F), and briefly to 80°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
