What your process engineer actually checks

What your process engineer actually checks

Detail, wash time and finish

A model resin is judged on surface detail, how long it spends in the washer and how it takes paint. xMODEL15-Gray runs at 200–300 mPa·s, washes in under about 5 minutes in xClean then IPA, and cures to 78–80 D Shore so edges and draft angles stay crisp through sanding and priming.

About this product

Nexa3D xMODEL15-Gray is an economical 405 nm LSPc photopolymer for fast, high-detail concept and appearance models on the XiP and XiP Pro. The neutral gray reads surface transitions and draft angles clearly in design reviews, and printed parts sand, prime, paint and plate cleanly.

Why engineers choose xMODEL15-Gray

Model-shop economics with the surface quality a design review needs.

Detail that survives handling

78-80 D Shore hardness and 1800 MPa tensile modulus keep edges crisp, so draft angles and small radii read correctly when the model is passed around a table.

Low viscosity, short wash

200-300 mPa·s at 30 °C drains fast off geometry and out of channels. Wash time stays under about 5 minutes in xClean followed by IPA.

Neutral gray for form studies

Gray shows surface transitions and parting lines that white or clear resins hide, and it sands, primes, paints and plates cleanly for appearance models.

Stable on the bench

0.7% water absorption over 24 h and 58.3 °C HDT at 0.45 MPa mean review models hold shape through a normal shop week rather than creeping.

How we supply xMODEL15-Gray

From formulation to a cured model on your bench.

Step 01
Formulated & tested

Genuine Nexa3D 405 nm LSPc chemistry, tested against the published mechanical and thermal values before it leaves the plant.

Step 02
Stocked & lot-matched

Held in US stock in sealed 1.5 kg cartridges. We lot-match repeat orders so a second batch of models matches the first.

Step 03
Print, wash & cure

You get the validated XiP exposure profile plus the wash and post-cure route, so the first cartridge produces usable parts.

Compatible printers & post-processing

The 1.5 kg cartridge feeds the Nexa3D XiP and XiP Pro. The same xMODEL15-Gray formulation is also supplied in a 5 kg bottle for the NXE 400 and NXE 400 Pro, so a model shop can run one resin across desktop and production LSPc machines. Post-processing is short: wash in xClean and then in IPA, keeping total wash time under roughly 5 minutes, let the part dry fully, then UV post-cure. Cured models sand, prime, paint and plate without special surface preparation.

Tell us your printer, target detail level and finishing route – a materials engineer will confirm whether xMODEL15-Gray fits, send the exposure profile and size the order. Sub-4h reply, NDA standard.

Common questions

Don't see yours? Email [email protected] — NDA standard, typical reply within 4 hours.

Which printers is Nexa3D xMODEL15-Gray compatible with?
The 1.5 kg cartridge of Nexa3D xMODEL15-Gray is made for the Nexa3D XiP and XiP Pro, which cure at 405 nm using LSPc. The same formulation is supplied in a 5 kg bottle that feeds the NXE 400 and NXE 400 Pro, so a shop running both desktop and production machines can standardise on one model resin. We ship xMODEL15-Gray with the validated exposure and cure profile for your specific printer, so you are not calibrating from scratch on the first cartridge. Tell us which Nexa3D machines you run and we will confirm the right package size and settings.
What colors and package sizes does xMODEL15-Gray come in?
Nexa3D xMODEL15-Gray is supplied in neutral gray, in a 1.5 kg cartridge for the XiP and XiP Pro and a 5 kg bottle for the NXE 400 series. Gray is the default choice for form studies because it reads surface transitions, parting lines and draft angles far more clearly than white or clear resin under normal shop lighting. If you need a different shade or volume, the wider Nexa3D LSPc line covers tough, dental, castable and flame-retardant grades in several colors. Ask us and we will match a resin and quantity to your printer and monthly usage.
How do I wash and cure parts printed in xMODEL15-Gray?
Post-processing xMODEL15-Gray is short. Wash the printed part first in xClean and then in IPA, keeping total wash time under roughly five minutes so fine detail is not softened, let the part dry completely, then UV post-cure. Cured xMODEL15-Gray sands, primes, paints and plates without special surface preparation, which is why model shops use it for appearance parts. Over-washing is the most common mistake we see: it dulls edges and leaves a tacky surface after cure. If you want exact wash and cure times for your washer and cure unit, our engineers will send them.
What is xMODEL15-Gray best used for?
xMODEL15-Gray is a concept and appearance model resin. It suits early form studies, ergonomic mock-ups, housing fit checks and painted design-review models, where detail and finish matter more than mechanical load. With 55 MPa tensile strength, 1800 MPa modulus, 10% elongation and 58.3 °C HDT at 0.45 MPa it is a rigid, economical model material rather than an engineering or end-use grade. If parts have to survive functional testing, heat or repeated assembly, ask us about the tougher and higher-temperature resins in the Nexa3D LSPc line instead.
How should xMODEL15-Gray be stored?
Store Nexa3D xMODEL15-Gray in its sealed original cartridge, away from direct sunlight and any UV source, at a stable room temperature. Photopolymers cure on exposure to light, so an open or partly used cartridge left in a bright room will start to gel. Keep the cartridge upright, and let the resin reach room temperature before printing: viscosity is quoted at 30 °C (200–300 mPa·s) and cold resin flows differently. We ship lot-matched cartridges from US stock so repeat orders behave the same. Ask us for the safety data sheet if your facility needs it for chemical storage records.
Is xMODEL15-Gray biocompatible or otherwise certified?
No. Nexa3D xMODEL15-Gray carries no biocompatibility, medical or flame-retardancy certification. It is a general-purpose model and appearance resin, so it should not be used for skin-contact, intraoral or patient-facing parts, and we will not claim otherwise. If your application has to meet a standard, ask us about xMED412 and xMODEL 2505, which are formulated for medical and dental workflows, and we will send their current documentation so you can check it against your requirement. The technical and safety data sheets for xMODEL15-Gray are linked on this page for your material records.
Can I test xMODEL15-Gray before ordering volume?
Yes. If you are not ready to commit to volume, request the Nexa3D LSPc resin sample kit and print xMODEL15-Gray on your own XiP first. The sample is paid, and it lets you check detail, wash behaviour, cure time and how the surface takes primer and paint on your actual geometry rather than on a test coupon. Once the resin is qualified we support lot-matched repeat orders, volume pricing and official purchase orders for production accounts. Tell us your printer and monthly volume and a materials engineer will size the first order and quote the follow-on cartridges.
