Working with Rigur RGD450
Is Rigur easy to machine?
Drilling, tapping and sanding are fine at low speed; keep tooling cool since the part softens above ~45 °C.
Can Rigur be welded?
Thermoset — no melt welding; join with cyanoacrylate, epoxy or UV-cure acrylate adhesive.
Can Rigur be formed, bent or molded?
Built only by PolyJet jetting/UV cure; wall thickness ≥1 mm, and design living hinges thin (0.5–0.8 mm) with the hinge axis in the print plane.
What surface finishes work on Rigur?
Water-jet or caustic bath support removal, then sand and prime; always apply UV-blocking clear coat or paint for parts kept in daylight.

Rigur RGD450 — frequently asked
What is Rigur RGD450 used for?
Rigur RGD450 is typically used for snap-fit closures, living hinges and sports equipment mockups. In short: tougher polypropylene simulant; best snap-fit PolyJet resin; higher strength than Durus.
What is the yield strength of Rigur RGD450?
Rigur RGD450 has a typical yield strength of 38 MPa (5.51 ksi) and a tensile strength of 42 MPa (6.09 ksi) — weaker than 64% of polymer grades. Strength varies by condition: see the 3 listed tempers.
Is Rigur RGD450 easy to machine?
Reasonably — machinability is rated fair (45/100, worse than 78% of polymer grades). Drilling, tapping and sanding are fine at low speed; keep tooling cool since the part softens above ~45 °C.
Can Rigur RGD450 be welded?
Not readily — weldability is rated not recommended (5/100). Thermoset — no melt welding; join with cyanoacrylate, epoxy or UV-cure acrylate adhesive.
What surface finishes work on Rigur RGD450?
Water-jet or caustic bath support removal, then sand and prime; always apply UV-blocking clear coat or paint for parts kept in daylight.
Can Rigur RGD450 be formed, bent or molded?
Built only by PolyJet jetting/UV cure; wall thickness ≥1 mm, and design living hinges thin (0.5–0.8 mm) with the hinge axis in the print plane.
What is the maximum service temperature of Rigur RGD450?
Rigur RGD450 is rated for continuous use to about 40°C (104 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between Rigur RGD450 and Rigur GLOSSY?
RGD450 is the default condition — default white Rigur cartridge printed on Objet/Connex PolyJet systems for PP-like functional prototypes. GLOSSY: choose when smooth, near-molded surface finish and slightly higher measured strength on skin surfaces are wanted. Yield strength is 38 MPa in RGD450 versus 40 MPa in GLOSSY.
