Buying a 3D printer is the first step the next step is buying the correct filament, it's important to know the type of material to use and their qualities. There are many materials that you can print with all other different characteristics which can be defined to certain tasks. Filaments come in a range of colours and are usually placed on printer spools to be placed in or on 3D printers.
The most frequently used filaments are plastics within FDM, SLA and SLS printing technologies. The fused deposition modelling (FDM) printing filaments are used the most within a range of environments.
Acrylonitrile Butadiene Styrene (ABS) is an extra-strong impact-resistant filament ideal for 3D printing of solid printed products. ABS filaments are used in FDM technologies, its the most affordable and accessible 3D printing technology. Due to the process stability and physical features of ABS, it is a widely used thermoplastic polymer in industry. The material is also very light and durable making ABS particularly suitable for tools, toys and all kinds of utensils. Printed at a slightly over-average temperature for ABS, this filament gives extra strong 3D print results.
Also known as Polylactic Acid (PLA), it's manufactured using renewable resources. An advantage of using PLA over ABS is its biodegradable qualities, however, it can deteriorate when in contact with water. PLA can be one of the easiest materials to print with but can have a tendency to shrink after being printed.
Polyethylene Terephythalate (PET) is used in today's environment within plastic bottles. PET main advantage is its food-safe properties, coupled with good chemical resistance. This material can be 100% recyclable and achieving the best printing results, print at 75-90ºC.
There are also other materials that can be used, Stereolithography materials (Epoxy Resins), Polycarbonate, HDPE, Metal filament, carbon fibre mix.
