Working with Rigur DM-RIGUR-BLEND
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 DM-RIGUR-BLEND — frequently asked
What is Rigur DM-RIGUR-BLEND used for?
Rigur DM-RIGUR-BLEND 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 DM-RIGUR-BLEND?
Rigur DM-RIGUR-BLEND has a typical yield strength of 22 MPa (3.19 ksi) and a tensile strength of 30 MPa (4.35 ksi) — weaker than 78% of polymer grades. Strength varies by condition: see the 3 listed tempers.
Is Rigur DM-RIGUR-BLEND easy to machine?
Not especially — machinability is rated fair (40/100, worse than 82% of polymer grades). Drilling, tapping and sanding are fine at low speed; keep tooling cool since the part softens above ~45 °C.
Can Rigur DM-RIGUR-BLEND 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 DM-RIGUR-BLEND?
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 DM-RIGUR-BLEND 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 DM-RIGUR-BLEND?
Rigur DM-RIGUR-BLEND is rated for continuous use to about 38°C (100 °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.
