What your process engineer actually checks
Toughness that survives post-cure
xPP405's 100% elongation and 51 J/m Izod are post-cure numbers, and over-curing this resin costs you exactly that toughness. We share the exact wash and cure recipe — xClean then IPA, 1 × 60 min in xCURE — so parts land on the datasheet.
A materials engineer on the line
Resin selection, exposure tuning, post-cure and finishing — answered by engineers who print Nexa3D LSPc in-house. Sub-4h reply, NDA standard.
Nexa3D xPP405 Black is a polypropylene-like LSPc photopolymer — tough, impact-resistant and semi-rigid, with roughly the stiffness of molded unfilled polypropylene and about 100% elongation at break. Supplied in a 5 kg container for the NXE 400 / 400Pro.
Why engineers choose xPP405
The LSPc resin you reach for when parts have to bend, snap and survive handling.
PP-like toughness
About 100% elongation at break and 51 J/m notched Izod — parts deform and absorb impact instead of shattering like a standard rigid resin.
Stiffness of unfilled PP
1300 MPa tensile modulus and Shore D 76 put xPP405 in the same stiffness band as molded, unfilled polypropylene — familiar behaviour for design validation.
UV and weather stable
Tested for UV ageing (ASTM D4329) and heat ageing (ASTM D3045), with industrial chemical-resistance data in the datasheet — built for end-use parts, not just models.
Biocompatibility screening passed
Cytotoxicity (ISO 10993-5) and irritation (ISO 10993-23) both pass per the manufacturer’s datasheet. Flammability rated UL94 HB at 2 mm.
How we supply it
Lot-sealed resin, a validated print profile and exact post-cure recipes in every order.
Lot-sealed & traceable
Every 5 kg container ships sealed with its Nexa3D lot. Shake and pour — no mixing, no additives.
Validated NXE 400 profile
The resin ships with Nexa3D’s validated LSPc profile; our engineers add exposure and orientation guidance for your parts.
Wash & cure to spec
xClean (max 2 min) then IPA (max 5 min). Post-cure 1 × 60 min in xCURE, or 2 × 30 min in XiP Cure, to reach datasheet values.
Typical applications
Where a tough, chemically stable, PP-like material earns its place.
