Nexa3D xMODEL35-Gray Resin – Rigid High-Temp Photopolymer for XiP | 1.5 kg
What your process engineer actually checks
Cure state, not just the datasheet
The 87 °C HDT at 1.82 MPa and 2300 MPa flexural modulus quoted for xMODEL35-Gray assume a full post-cure — 2 × 30 min in the XiP Cure or 60 min in the xCURE, after a 2 min xClean and 5 min IPA wash on a fully dried part. We ship the validated wash and cure routine with the cartridge so your measured parts match the TDS.

Nexa3D xMODEL35-Gray is a rigid LSPc photopolymer that combines stiffness, strength and temperature resistance in one model resin. Gray pigment reads surface detail cleanly under raking light, so design reviews happen on the part.
Why engineers choose xMODEL35-Gray
The step up from xMODEL15 when a XiP part must hold shape under load and warmth.
87 °C HDT at 1.82 MPa
Heat deflection is 87 °C at 1.82 MPa and 64 °C at 0.45 MPa (ASTM D648) — fixtures and housings hold shape in a warm shop.
2300 MPa flexural modulus
2300 MPa flexural modulus and 108 MPa flexural stress (ASTM D790) keep thin walls and long spans from sagging.
53 MPa tensile, 83 D hardness
53 MPa tensile strength, 1765 MPa Young’s modulus and 83 D Shore hardness (ASTM D638 / D2240) — a hard surface that sands and paints well.
UL94 HB and low water pickup
UL94 HB at 1.5 mm and 0.42% water absorption over 24 h (ASTM D570), so parts hold properties in humid storage.
How we supply xMODEL35-Gray
From sealed cartridge to cured part, with the LSPc settings.
Formulated & tested
Genuine Nexa3D chemistry, characterised against the ASTM methods listed below. No relabelled resin.
Stocked & lot-matched
1.5 kg cartridges in US stock, lot-matched on request, so a qualification batch and the follow-on print alike.
Print, wash & cure
Ships with the validated XiP and XiP Pro exposure profile plus the wash and post-cure routine.

Printed properties depend on part geometry, orientation and post-cure. Values are typical, not a specification.
Typical applications
Where a stiff, heat-tolerant gray model earns its place.
Compatible printers & post-processing
This 1.5 kg cartridge feeds the Nexa3D XiP and XiP Pro LSPc printers. The same resin also comes in a 5 kg bottle for the NXE 400 and NXE 400 Pro. Post-processing is a two-stage wash: up to 2 minutes in xClean, then up to 5 minutes in IPA. Dry fully, then UV post-cure — 2 × 30 minutes in the XiP Cure, or one 60-minute cycle in the xCURE. Full cure is what delivers the quoted 87 °C HDT and 2300 MPa flexural modulus; under-cured parts fall short of both.
