MATERIALS

MATERIAL CHOICE

Material choice is a crucial step in getting a part 3D printed. Depending on the use of the part, such as form, fit or function, this can directly influence your material choice. For example, the low cost and ease of printing makes PLA an excellent material choice for form prototypes. But the brittle nature and poor elongation make it a bad choice for some functional parts.

Depending on the requirements, we can recommend a material type for you. Listed below are typical 3D printing materials used in 3D Printing, for both FDM and SLA 3D Printing types. You will find a selection of scaled graphical representations of each materials characteristics to help you choose what's right for you.

The ease of printability of each material, and the direct material cost will both influence the cost attributed to the finished part. Other considerations for the material are for performance and aesthetics such as colour, opacity and surface roughness.

COLOUR CHOICE

Within each material type, a range of colours are available to print in. These colours can be selected to be the final surface finish of the part. For parts without specific finish requirements, a simple natural, black or white can be selected as these are most common. This is a good choice for parts that will be painted, or sanded and refined further as some premium colours are often more expensive.

Along with colour choice, some materials will also have translucent options. With fused deposition modelling, the option for a fully transparent part is unfortunately not possible. PETG and PC offer some excellent translucent filaments.

Here at voxel design, we keep certain colours in stock at all times, these can be seen below in our colour choice matrix. Other colours and premium filaments can be ordered, and if there is a type of finish you want to achieve with your part we will be as accommodating as possible.
