Colour 3D printing. Polyjet.

3D Printing in colour.

3D Printing in Full Colour. For when you need to communicate & visualise your design ideas.

Produce stunning visualisations of your product designs or architectural layouts for presentations, events and displays. 

Based on an evolution of 'Ink jet' print head technology this 3D Printing process mixes a range of coloured materials & cures them to produce 3D printed versions of your designs in full colour.   The final models appear incredibly life like and have a real 'wow' factor.

Full Colour. 3D printing for concept modelling.

3D Printing with 3D-Alchemy™ in colour and visualising your designs gives you the best tool to communicate the subtleties of your concept to clients and colleagues alike.

Combine colour and texture to create models that appear life like & real, making the process perfect for product development and architectural applications. The 'Polyjet' colour 3d printing process is based on mixing 3 rigid, flexible or colour materials.  

The new J750 system 3D prints using CMYK (Cyan, Magenta, Yellow and Black) materials which the machine software references in RGB colour codes to give you Rubber Like flexible in Spot colour or Rigid parts in full colour. The system is capable of reproducing 360,000 colours.

While most 3D printing technologies can be finished for painting as a separate stage, this process adds digital colour as your model is being built.

Flexible, Rigid, Large Format Colour designs.

The Polyjet 3D printing technology is arguably the most effective way to produce 3D printed models with fine details in colour and gives you a new tool for prototyping and evaluating designs without having to commit to Vac Casting tooling or resort to painting and model making.

  • 30 micron layer thickness. 
  • Supports wall thickness's & details down to 1mm in rigid and 1.5mm in Flexible. 
  • Mix solid & flexible elements in the same design.
  • 3D-Print textured, full colour designs in Rigid materials.
  • 3D-Print 'Spot' colour design in Rigid and Flexible materials.
  • Produce visualisation and display models.
  • Large format build size: Up to 500 x 400 x 200 mm
  • Acceptable files types:
    • .STL file separated in to shells for each spot colour.
    • .wrl (VMRL)  files for full colour, textured designs.
    • SLDPRT
    • STEP and other native cad formats.
  • NEW J750 3d printing system.

3D Printing in Colour. Applications.

Our clients have been using colour 3d printing for a range of applications, but focusing on product development where the service gives them visuals for fit and form testing, plus pre production photography.

Our clients on the animation industries have also taken advantage of the system, producing character visuals to help with development.

Engineers and academics are using the system to produce physical rendering of FEA results. 

Information on how to produce the VMRL (.wrl) 3D print file can be found in a handy Grabcad Blog Post

What our customers say about our 3d printing service

Great news! I won the Young Engineer for Britain: Engineering Excellence Award at the NEC Big Bang Fair yesterday. I'd just like to thank you again for your generosity and your excellent prints. I'll be sure to recommend your company in future and I wish you all the best.

Michael, student engineer.

What our customers say about our 3d printing service

"Quick service, good quality and fast delivery.... Always pleased with the quality of the parts and delivery times. Prices were also very reasonable. I really appreciate how 3D Alchemy was able to accommodate some builds for parts I needed desperately."

Mikel, Industrial fastener company.
