What your process engineer actually checks
Speed without giving up toughness
x45 prints in draft mode above 15 cm/hr yet lands 52 MPa tensile, 95 MPa flexural and Shore D 85 — fast turnaround that still survives functional fit checks, with a 120 °C HDT that holds shape near warm tooling.

Questions on resin compatibility, wash media or post-cure settings? Our engineers have run these materials on Nexa3D LSPc printers. Sub-4h reply, NDA standard. Use the Talk to materials engineer button above.
Nexa3D x45 (Natural) is a fast, general-purpose LSPc photopolymer — the BASF Forward AM Ultracur3D ST 45 formulation — that prints tough, dimensionally stable models and functional prototypes on Nexa3D resin systems at draft-mode build speeds above 15 cm/hr, in a clear Natural finish.

Why engineers choose x45
Draft-speed prints that still behave like a functional part — spec numbers from the Nexa3D datasheet.
Draft speed above 15 cm/hr
Robust print styles give high first-time build success, so a full plate comes off the NXE or XiP in a fraction of laser-SLA time.
52 MPa tensile, 12% elongation
Notched Izod impact of 20 J/m and Shore D 85 give snap-fits and functional prototypes that survive fit checks and handling.
95 MPa flex, HDT 120 °C
Flexural modulus of 2.1 GPa and a 120 °C HDT at 0.45 MPa keep jigs and fixtures rigid on the bench and near warm tooling.
Clear Natural optic
The Natural grade prints with good optical clarity for see-through models and light-path checks; also stocked in Black.
How we supply x45
Every bottle arrives ready to run on your Nexa3D printer — no parameter hunting.
Lot-coded & profiled
Each bottle ships sealed and lot-coded with the validated LSPc print profile for your NXE 400/400Pro or XiP.
Wash + post-cure dialed in
The data sheet includes wash media and UV post-cure settings we’ve run in-house, so mechanicals land on spec, not guesswork.
Stocked & shipped
Held in US stock and dispatched in 1–2 business days; 1.5 kg and 5 kg formats, with volume and PO orders handled by our materials desk.
Typical applications

Compatible printers & workflow
- Runs on Nexa3D LSPc resin systems — NXE 400 / 400Pro and the XiP desktop printer.
- Wash in the recommended solvent, then UV post-cure per the data sheet; a wash and cure station are required and sold separately.
- Available in Natural (clear) and Black, in 1.5 kg and 5 kg bottles.
