What is Durus RGD430?
Durus RGD430 is Durus in the RGD430 grade — default and only chemistry of this grade: choose for PP-like flexible snap-fits, living hinges and thin-wall enclosures on PolyJet machines. Durus RGD430 has a yield strength of 22 MPa (3.19 ksi) and a tensile strength of 25 MPa (3.63 ksi) — weaker than 78% of polymer grades. Elongation at break is 45% and the elastic modulus is 1.1 GPa (0.16 Msi). Durus RGD430 has a density of 1.17 g/cm³ (0.0423 lb/in³), lighter than 54% of polymer grades. Its glass-transition temperature is 43°C (109 °F).
Limitations
- Limited service temperature — 45°C (113 °F), worse than 98% of polymer grades

Working with Durus RGD430
Is Durus easy to machine?
Drill and trim with sharp tools at low speed and no coolant heat build-up — the resin is soft, gummy and softens near 45 °C.
Can Durus be welded?
Thermoset network cannot be heat-welded; join with cyanoacrylate or UV-curable acrylic adhesive.
Can Durus be formed, bent or molded?
Not moldable; parts are built layer-by-layer at 28–32 µm on PolyJet heads, then support (SUP705/706) is water-jet or caustic-bath removed.
What surface finishes work on Durus?
Sand and prime before painting; keep parts dry and out of sunlight, and seal or clear-coat if any UV exposure or humidity-driven creep is expected.

Durus RGD430 — frequently asked
What is Durus RGD430 used for?
Durus RGD430 is typically used for living hinge prototypes, packaging mockups and consumer product housings. In short: polypropylene-simulating PolyJet resin; semi-rigid, flexes without fracture; superseded by Rigur.
What is the yield strength of Durus RGD430?
Durus RGD430 has a typical yield strength of 22 MPa (3.19 ksi) and a tensile strength of 25 MPa (3.63 ksi) — weaker than 78% of polymer grades. Strength varies by condition: see the 3 listed tempers.
Is Durus RGD430 easy to machine?
Reasonably — machinability is rated fair (45/100, worse than 78% of polymer grades). Drill and trim with sharp tools at low speed and no coolant heat build-up — the resin is soft, gummy and softens near 45 °C.
Can Durus RGD430 be welded?
Not readily — weldability is rated not recommended (5/100). Thermoset network cannot be heat-welded; join with cyanoacrylate or UV-curable acrylic adhesive.
What surface finishes work on Durus RGD430?
Sand and prime before painting; keep parts dry and out of sunlight, and seal or clear-coat if any UV exposure or humidity-driven creep is expected.
Can Durus RGD430 be formed, bent or molded?
Not moldable; parts are built layer-by-layer at 28–32 µm on PolyJet heads, then support (SUP705/706) is water-jet or caustic-bath removed.
What is the maximum service temperature of Durus RGD430?
Durus RGD430 is rated for continuous use to about 45°C (113 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between Durus RGD430 and Durus GLOSSY?
RGD430 is the default condition — default and only chemistry of this grade: choose for PP-like flexible snap-fits, living hinges and thin-wall enclosures on PolyJet machines. GLOSSY: pick for the smoothest as-printed surface and slightly higher measured strength on up-facing walls; geometry must allow support-free faces. Yield strength is 22 MPa in RGD430 versus 24 MPa in GLOSSY.
