Prime gray costs 1,55 EUR per cubic centimeter (plus a 5 EUR handling cost per model). For each extra copy of your model you order, the handling cost gradually drops from 5 EUR to 2,5 EUR per model. After 5 parts you reach a price of 2,5 EUR.
Models made in Prime Gray are typically used as high quality show models. Design and engineering departments use the models as visual prototypes or for presentations. We are now introducing this material here because we’ve noticed that it works really well for character and toy models. For some reason, the combination between the Air Force Gray color, the smooth surface, and the level of detail possible make desk toys and character models look much more desirable than if they are done in other 3D printing materials.
Stereolithography is used to build your design with this material. Starting from a 3D model, a model is built by cutting it into thin layers via specialized software. A support structure is created, where needed, in order to deal with overhangs and cavities.
The process takes place in a large tank, and begins when a layer of liquid polymer is spread over a platform. This machine then uses a computer controlled laser to draw the first layer onto the surface of a liquid polymer, which hardens where struck by the laser. The model is then lowered and the next layer is then drawn directly on top of the previous one. This is repeated until the model is finished. In this way, layer by layer, an object is “drawn” in the liquid by the beam, with the layers being consolidated throughout the process.
When the object is complete, it is raised out of the tank via the supporting platform – much like a submarine rising to the surface of the water – with the excess liquid flowing away. The supports are removed manually after the model is taken from the machine.
Learning about our materials is one thing, seeing and touching them another. That's why we've designed sample kits based on our Periodic Table of Materials. Prime Gray is part of our basic sample kit. Available for 30€ with a 25€ voucher included.
