What is Rigur?
Rigur (RGD450) is a polypropylene-simulating PolyJet photopolymer and the tougher, more impact-resistant successor to Durus, available in glossy, matte and digital-material blends. It is used for snap-fit and living-hinge prototypes that must survive repeated assembly cycles; default values are 42 MPa tensile strength, 32% elongation and Shore D 80. As a thermoset it cannot be melt-welded, it softens above about 45 °C, and daylight exposure requires a UV-blocking coating. Durus (RGD430) is the softer, lower-strength predecessor. Rigur has a density of 1.17 g/cm³ (0.0423 lb/in³), lighter than 54% of polymer grades. Its glass-transition temperature is 48°C (118 °F). Rigur has a yield strength of 38 MPa (5.51 ksi) and a tensile strength of 42 MPa (6.09 ksi) — weaker than 64% of polymer grades. Elongation at break is 32% and the elastic modulus is 1.9 GPa (0.276 Msi).

Working with Rigur
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 — frequently asked
What is Rigur used for?
Rigur 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?
Rigur 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 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 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 is the maximum service temperature of Rigur?
Rigur 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.
