Professional quality photopolymer printing for medical applications, engineering, fine art or jewellery design

Stratasys J750

Our PolyJet device works with photopolymer materials. During the process, the head injects a liquid polymer resin layer by layer onto the work surface and then illuminates it with UV light.

The device can dispense seven different materials at the same time in cyan, magenta, yellow, black, or white. It can also operate with a special material that modifies physical properties and supports structure material, allowing for users to mix colours and choose the flexibility of the object if the raw material used is flexible. It can also make glassy and transparent objects. As with inkjet printers, over half a million colours and a wide range of properties can be mixed during printing.

Many different properties such as desired stiffness, flexibility and different combinations of transparency are feasible. This printer is capable of 0.016 mm layer thickness, which is about twice as thick as a human skin cell. The amount of post-processing required using this device is negligible compared to other technologies.

Printing Speed & Build Modes

The J750 can print at three different speeds and resolutions:

  • High Speed Mode: up to 3 base resins, 27-micron resolution
  • High Quality Mode: up to 6 base resins, 16-micron resolution
  • High Mix Mode: up to 6 base resins, 27-micron resolution

Source File

PolyJet also supports .STL files, but it is also possible to print directly from the original formats of the most popular CAD programs without .STL conversion. The wrl/wrml format with a texture file allows for coloured or textured files to be printed.

Possible Size of Layers

In addition to thicknesses of 16 and 27 microns, depending on model size, resolution, material use and detail, a fitting tolerance of around 200 microns for the entire model is expected.

Maximum Model Size

The printing area is 490 x 390 x 200 mm, but larger models can be printed in pieces.

Model Materials

The VeroTM range is recommended for transparent materials and natural colours.

For vibrant colours and neon effects, VeroMagentaV and VeroYellowV are the recommended products.

The TangoTM and Agilus30TM polymers are popular for prints requiring a flexible material.

For a fully transparent finish, VeroClearTM and RGD720 are recommended.

Stratasys Objet Eden260VS Dental

Our dental printer is one of the first mass production solutions for the expanding dental market, capable of printing hundreds of workpieces per day. The Stratasys Eden260VStm is a market leader for its high quality and cost-effectiveness.

Printing Time

The Eden260VStm is designed for continuous use and can print approximately 50-60 bridges and 400 tooth samples per day.

Source File

The printer supports .STL files, but it is also possible to print directly from the original formats of the most popular CAD programs without .STL conversion.

Layer Thickness

The device offers a layer thickness of 55 microns.

Maximum Model Size

The print area is 490 x 390 mm.

Model Materials

The device uses VeroDent products made from MED670 printing stock, a strong, durable material that offers a natural colour effect and allows for rich detail.

Polyjet transparent head

Human head in 1:4 ratio with annotated nasal cavities, oral cavities and sinuses, made as an educational aid. The head is completely transparent, but the different organs are separated by different colours. A 3D scanned version of the customer’s own face was reproduced.

MiniMe

Nowadays, our own 3D-printed images have become trendy gifts. Couples, parents and grandparents are gifting each other with their own colourful 3D printed miniature models, called MiniMe. Featuring both handheld scanners that can perfectly digitise the human body and a PolyJet printer that prints in rainbow colours, the UP-3D Centre also allows customers to immortalise themselves for eternity in the form of small or large 3D printed sculptures.
