What your process engineer actually checks

Gray data, not family data

The published values for xGPP-Gray are its own: 30 MPa ultimate tensile strength, 2100 MPa tensile modulus, 2% elongation at break, 84 D Shore hardness and a 93 °C glass transition. We quote the Gray sheet, not the Translucent one, and we confirm compatibility for the NXE 400 and NXE 400 Pro only.

About this product

Nexa3D xGPP-Gray is a BASF-formulated General Purpose Photopolymer for high-throughput, high-accuracy production and prototyping on the NXE 400 and NXE 400 Pro. Low shrinkage and injection-mould-quality surface finish, in the gray finish that shows draft lines and surface defects clear resins hide.

Grey parts printed in Nexa3D xGPP-Gray resin on an NXE build plate — xGPP-Gray parts straight off the NXE build plate.

Why engineers choose xGPP-Gray

Rigid, accurate and fast — the default resin for fit checks, fixtures and short runs.

93 °C glass transition

Parts hold their shape through warm assembly checks, shop-floor heat and summer shipping instead of drooping on the fixture.

84 D Shore, 2100 MPa modulus

Hard, rigid surfaces. Locating features on gauges and fixtures survive repeated cycles without wearing round.

LSPc area cure at 405 nm

Each layer is cured across the whole plate at once, so a full build finishes in the time a laser system spends tracing one part.

Low shrinkage, gray finish

Injection-mould-quality surfaces, and gray reads draft lines, parting seams and defects that translucent resins hide.

How we supply xGPP-Gray

Vendor-validated chemistry, lot traceability and a cure profile that matches your machine.

Step 01

Formulated & tested

xGPP-Gray is a BASF-formulated general purpose photopolymer, validated on the Nexa3D NXE 400 and NXE 400 Pro before it enters our catalogue.

Step 02

Stocked & lot-matched

Supplied to order in 5 kg (12 lb) jerricans with lot traceability, so a repeat production run prints from the same chemistry as the first.

Step 03

Print, wash & cure

Print at 405 nm on the NXE 400 or 400 Pro, wash and finish with the standard Nexa3D solvent workflow, dry, then UV post-cure to full properties.

Typical applications

Where xGPP-Gray earns its place on the NXE 400.

Form, fit and function

Design validation before tooling is cut

Gauges and fixtures

84 D locating features that resist wear

Topology and DfAM studies

Print the optimised geometry and load it

Demonstration models

Review parts with mould-quality surfaces

Painted or plated masters

Sands and primes cleanly for finishing

Short-run production parts

Bridge volumes where tooling is not justified

Compatible printers & post-processing

xGPP-Gray is qualified for the Nexa3D NXE 400 and NXE 400 Pro, cured at 405 nm under the LSPc process. Those are the only platforms we confirm — Nexa3D does not publish validated profiles for xGPP-Gray on the XiP or XiP Pro desktop machines, so we make no claim there. Mix the jerrican thoroughly before each print job and pour slowly into the vat so entrained air can clear before the build starts. Printed parts are washed and finished using the standard Nexa3D solvent workflow, dried, and then UV post-cured; the published 30 MPa ultimate tensile strength, 2100 MPa modulus and 93 °C glass transition are reached only after a full post-cure. Filter reclaimed resin back into the container between jobs.

Common questions

Which 3D printers is Nexa3D xGPP-Gray compatible with?

xGPP-Gray is qualified for the Nexa3D NXE 400 and NXE 400 Pro. Those are the only platforms we confirm — Nexa3D does not publish validated profiles for xGPP-Gray on the XiP or XiP Pro desktop machines, so we make no compatibility claim there. It cures at 405 nm under the LSPc process, which area-cures each layer rather than tracing it with a laser, so a full build plate finishes in the time a laser system needs for a single part. Send us your printer model and firmware version and our engineers will confirm the exposure profile before you order.

What colour and pack size does xGPP-Gray come in?

xGPP-Gray is supplied in gray, in 5 kg (12 lb) jerricans. Gray is the detail-showing finish in the xGPP family: it reveals draft lines, parting seams and surface defects that translucent or light-coloured resins hide, which is why fit-check and inspection parts are usually printed in it. The same general purpose photopolymer is also offered in translucent if you need to see inside the part. If you need a different colour or a volume we do not list, tell us your monthly consumption and we will quote it against your production schedule.

How are xGPP-Gray parts washed and post-cured?

Parts printed in xGPP-Gray are washed and finished using the standard Nexa3D solvent workflow, dried, and then UV post-cured. The published values — 30 MPa ultimate tensile strength, 2100 MPa tensile modulus and a 93 °C glass transition — are reached only after a full post-cure, so under-curing leaves parts softer and lower in Tg than the data sheet suggests. Gray parts sand and prime cleanly, which is why they are commonly used as painted or plated masters. Ask our engineers for the cure time we run for your part thickness and we will send it.

What is xGPP-Gray best used for?

xGPP-Gray is a general purpose production and prototyping photopolymer for form, fit and function work: gauges and fixtures, topology and DfAM studies, demonstration models, parts primed for painting or plating, and short-run production parts. Low shrinkage and injection-mould-quality surface finish make it a practical stand-in for moulded parts during design validation, and 84 D Shore hardness keeps locating features from wearing after repeated use. It is a general purpose resin, not a high-temperature or elastomeric one. Describe the part and its duty cycle and we will confirm whether xGPP-Gray is the right choice.

How should xGPP-Gray be stored and handled?

Store xGPP-Gray sealed in its 5 kg jerrican, away from daylight and UV sources, at room temperature. Mix the container thoroughly before each print job so pigment and fillers are evenly distributed, and pour slowly into the vat so entrained air has time to clear before the build starts. Filter reclaimed resin back into the container rather than leaving it standing in the vat between jobs. Handle with nitrile gloves and follow the safety data sheet supplied with the shipment. If you need the handling sheet ahead of delivery, ask us and we will send it.

Does xGPP-Gray carry any certifications?

No. xGPP-Gray carries no biocompatibility, food-contact or flame-rating certification, and we will not claim any. Nexa3D publishes mechanical and thermal data to ASTM D638 and ASTM D2240 plus a 93 °C glass transition figure, and that is the extent of the documented performance. Treat xGPP-Gray as an engineering prototyping and short-run production resin. If your application needs a certified material — patient contact, food contact or a UL flame rating — tell us the standard you have to meet and we will point you to a Nexa3D resin that actually holds that certification.

Can we test xGPP-Gray before committing to volume?

Yes. Request the Nexa3D LSPc resin sample kit and print xGPP-Gray on your own NXE 400 or NXE 400 Pro before you commit to volume. Because xGPP-Gray is supplied to order rather than held on the shelf, testing first is worth the time — it lets you confirm accuracy, surface finish and paint adhesion on your actual geometry before a production quantity is scheduled. We supply the validated cure profile with the sample. Tell us your monthly volume and target date and we will confirm lead time and volume pricing with the order.
