What your lab manager actually checks

A model that still matches the scan

1700 MPa tensile modulus and 5% elongation are post-cure numbers, and they are what let a margin be ditched by hand without chipping. The cartridge carries the validated XiP profile and we share the wash and cure settings, so the model you thermoform on is the model you designed.

About this product

Nexa3D KeyModel Ultra is the KeyPrint model resin in a 1 kg smart cartridge for the Nexa3D XiP and XiP Pro — a fast, dimensionally stable material for aligner thermoforming models, removable dies and restorative models that trim and carve without chipping.

Nexa3D KeyModel Ultra dental resin – 3D printed arch model with a clear thermoformed aligner — A KeyModel Ultra arch model with the aligner thermoformed over it.

Why dental labs choose KeyModel Ultra

Four properties that decide whether a model survives the rest of the workflow.

Dimensionally stable

1700 MPa tensile modulus and 1940 MPa flexural modulus (ASTM D638 / D790) — models hold their geometry between print and thermoforming.

Clean thermoforming release

Formulated so the pressure-formed sheet lifts off cleanly instead of grabbing the model surface and taking detail with it.

Carves without chipping

70 MPa flexural strength with 5% elongation at break — margins can be trimmed and ditched by hand without the edge crumbling.

Fast LSPc throughput

Prints at 100 µm layers for thermoforming models and 50 µm for dies — the throughput a lab needs to clear a day of cases.

From cartridge to finished model

Three steps that decide whether the model matches the scan.

Step 01

Print on LSPc

Drop the cartridge into the XiP or XiP Pro. The NFC chip loads the validated KeyModel Ultra profile in NexaX — 100 µm for models, 50 µm for dies.

Step 02

Wash

Clean in xCLEAN or IPA and keep soak times short. An over-soaked model loses crisp margins, which is exactly what you printed it for.

Step 03

Cure

UV post-cure at 405 nm to reach the published mechanical values, then trim, ditch and thermoform as your workflow requires.

Common questions

Which printers does the 1 kg KeyModel Ultra cartridge fit?

This 1 kg smart cartridge is the Nexa3D XiP and XiP Pro format. It drops in and the NFC chip hands NexaX the validated KeyModel Ultra profile and lot data, so exposure is not something you tune by hand. NXE 400 and 400Pro machines feed from bottles and take the 5 kg KeyModel Ultra Ivory pack instead. If you are not certain which format your machine uses, send us the serial number and we will confirm before the order ships.

What layer height should I print KeyModel Ultra at?

KeyPrint validates KeyModel Ultra at 100 µm for thermoforming models and 50 µm for removable dies and detailed restorative models. The 100 µm setting is the throughput choice for a lab clearing aligner cases; 50 µm is for work where the margin has to be read under magnification. Both profiles ship with the cartridge. If your case mix is mostly one or the other, we can help you plan a build plate layout that keeps the printer busy overnight.

Does KeyModel Ultra release cleanly when thermoforming?

Clean release is one of the properties KeyPrint formulates KeyModel Ultra for — the pressure-formed sheet lifts without grabbing the model surface. That only holds if the model is properly washed and fully post-cured: residual uncured resin on the surface is what makes a sheet stick and tears detail off the model. Wash briefly, dry completely, then cure at 405 nm before the model goes anywhere near the thermoforming machine.

Can I trim and ditch margins on a KeyModel Ultra model?

Yes — that is what the 70 MPa flexural strength and 5% elongation at break are there for. The material carves and ditches by hand without the margin edge crumbling, which is the usual failure mode on brittle model resins. Use a sharp bur and light pressure as you would on stone. If your technicians work a lot of die margins, consider printing dies at 50 µm so the printed edge is already crisp before any hand work.

What wash and cure equipment does KeyModel Ultra need?

You need a wash station and a 405 nm cure unit; neither comes with the resin. The Nexa3D Wash+Cure handles both for the XiP in one desktop unit, and xCLEAN or IPA serves as the wash solvent. Keep wash times short so the model does not swell and lose margin definition. We supply the wash and cure hardware, the solvent and the spares alongside the resin, so the whole chain and its support come from one place.

Is KeyModel Ultra suitable for patient-contact appliances?

No. KeyModel Ultra is a model and die material — models, dies and thermoforming formers. The appliance itself is the thermoformed sheet or a purpose-built appliance resin, not the printed model. For patient-contact printed appliances we stock the KeyPrint materials formulated and tested for those indications, such as KeySplint Soft for splints and nightguards. Always confirm indications against the current KeyPrint instructions for use for your region.

How should the cartridge be stored?

Keep the cartridge sealed, upright and out of daylight and UV lamps — photopolymer cures slowly in ambient light. Store at normal indoor room temperature rather than an unheated store or a hot vehicle. Agitate before printing so the resin is homogeneous. Each cartridge is labelled with its lot and expiry; work from that date instead of a rule of thumb, and never decant used vat resin back into a sealed cartridge.
