Nexa3D x45 Black Resin 5kg
Tough. Fast. Heat-stable. Nexa3D x45 Black is a functional photopolymer for prototypes and production models that have to survive handling, assembly and test — 95 MPa flexural strength, 20 J/m notched Izod and a 120 °C heat-deflection temperature, with a draft mode that pushes build rates past 15 cm/hr. The deep black finish needs little cosmetic work.

What your engineering team actually checks
Fast enough to iterate, tough enough to test
x45 Black prints past 15 cm/hr in draft mode yet lands at 95 MPa flexural strength, 20 J/m notched Izod and a 120 °C HDT. Parts survive press-fits, drops and warm test rigs instead of shattering — so the same material covers the design loop and the functional build.
A materials engineer on the line
Send us the part and the load case. Our engineers print these materials in-house and will tell you whether x45 Black clears it, or point you at the resin that does — sub-4h reply, NDA standard.
Nexa3D x45 Black is a tough, fast-printing photopolymer for functional prototypes and production models that have to survive handling, assembly and test. Flexural strength 95 MPa, HDT 120 °C and Shore D 85, with a draft mode that pushes build rates past 15 cm/hr. Supplied as a 5 kg bulk bottle.
Why engineers choose x45 Black
Speed and toughness in one material, so iteration doesn’t cost you a week.
Remarkable build speed
Draft build mode drives print rates beyond 15 cm/hr on Nexa3D LSPc machines — same-day iterations instead of overnight waits.
Tough, not brittle
52 MPa tensile strength, 95 MPa flexural strength and 20 J/m notched Izod with 12% elongation — parts take a drop and a press-fit instead of shattering.
Holds heat to 120 °C
HDT of 120 °C at 0.45 MPa means parts stay dimensionally honest in warm test rigs, under-hood fixtures and paint-cure cycles.
First-time build success
Robust print styles and consistent out-of-printer properties mean fewer failed builds and less time spent re-running plates.
From plate to functional part
Validated print and cure profiles ship with the resin — no parameter guesswork.
Print fast
Run x45 Black on your Nexa3D LSPc printer using the validated profile, or switch to draft mode when you need the plate back the same day.
Wash
Wash parts in IPA and air-dry. Clear internal channels and blind holes before curing so no uncured resin is trapped.
Post-cure & finish
Final-cure to develop full strength and HDT, then sand, bead-blast or paint — the deep black finish needs little cosmetic work.
