FDM 3D PRINTER
What materials can I use?
- PLA (Polylactic Acid) – General Purpose and Renewable
- ABS (Acrylonitrile Butadiene Styrene) – General Purpose but tougher
- Nylon – Great for mechanical parts
- CPE (Copolyester) – Tough and Durable
- PC (Polycarbonate) – Tough and suitable for High Temperatures
- PP (Polypropylene) – Stress resistant
- TPU 95A (Thermoplastic Polyurethane) – Semi-flexible properties
- PVA (Polyvinyl Alcohol) – Water soluable, great support material
Please be aware that we normally only provide PLA and PVA. We may have stock of some other types so please check with the Technical Demonstrator.

How do I prepare a file?
When preparing your file there are certain things that you will need to ensure before you send this to us.
1. When you export your file all seperate componants should be exported as individual files rather than one whole piece.
2. Make sure that your file is at the correct scale to be printed. All .stl files export to mm. So you need to ensure the dimentions are converted to the mm equivalent if you have been working in a program that uses cm for example.
3. Componants that are connected should have been Booleaned together into one model. Printing a file whilst seperate parts overlap can cause errors.
4. Your model should be considered closed for your print to work. Any file that is still considered open will only be printed if the file looks ok in the printers native software. You can check if your model is closed in the object properties panel.
5. When exporting ensure you have exported at the right tollerance or polygon density. The tighter (lower figure) the tollerance the better the quality of print. The lower the tollerance (higher figure) the lower the quality and more faceted your print will look.
File Preparation for Rhino 6
1. Ensure that your final model parts are booleaned together if they are supposed to be attached.
2. Select the part you want to export and type ‘export‘ in the command bar or go to File > Export Selected…
3. In the export menu choose ‘Stereolithography (.STL)‘ as the file type and click Save
4. When prompted adjust the tolerance of the export to quality of export you want to achieve. The tolerance is a measurement in millimetres of how far away the polygon surface can be from the original form. The smaller the tollerance measurement the closer the polygon surface will be and the more polygons there will be in the model. The more polygons there are the smoother the surface you will have. 0.01mm is a good standard to work with but on large models this can make the file size large, so on larger files you may want to consider a tolerance between 0.05mm and 0.1mm. You can preview the mesh that will be created by clicking on the Preview button. Once happy click on OK.
5. Finally choose the .STL type. For 3D prints it is best to stick to Binary. If the file export size looks like it is going to be too big at this stage you can go back and adjust the tolerance. If happy with this click on OK to complete the export. You will be prompted in the command bar once the export is complete.
