3D Printer Filament is the material used for printing 3D objects. There is a wide variety of different filament types to use for 3D printing projects. But, how…
Soft PLA is a flexible filament that feels like rubber. It can be used to print flexible parts such as soft toys, flip-flops, molds, tires, or gripping surfaces.The filament is extremely tough and resistant to delimitation which makes it awesome material to experiments but sometimes tricky to print with.
Filabot Filaflex, Black. FilaFlex is a high flexible material similar to NinjaFlex but even softer. Temp range from 220 to 230°C. It doesn’t require a heated bed and is non-toxic and resistant to acetone, fuel, and dissolvent. Both NinjaFlex and FilaFlex are rubber-like materials and less prone to deformation from stretching than soft PLA, which is another example of flexible materials for 3D printing.
NinjaFlex TPE Filament color FireNinjaFlex. TPE filament is highly elastic and feels like rubber bouncing back and forth into shape, excellent abrasion resistance, as well as consistent diameter and smooth feeding, it easily sticks to build platform and bonds between layers. Printing temp range is 210 – 230°C. Filament. Not recommended for use with food. NinjaFlex filament is one of examples of thermoplastic elastomer (TPE) that is especially flexible for 3D printers.
Polycarbonate (PC) is an extremely strong, impact resistant thermoplastic, and heat resistant. 3D parts printed with PC are accurate, strong and durable. PC filament type has the second highest tensile strength among all FDM materials. The material is also biocompatible and can be sterilizable that is why it is so extremely popular for prototyping, functional testing, tooling, and composite work. The material should be extruded at or above 300°C and high heat deflection temperature is 138°C.
PETT “T-glase,” short for tough glass, is another type of clear filament, and tougher than PET. Suggested range temp is from 212°C to 224°C.This filament like PET need to be stored in a dry place. The main characteristics of PETT t-glase are strength especially with the larger nozzles used, biocompatibility, and FDA approval for use in food containers.
PET (PolyEthylene Terephthalate) known from plastic bottles, in its original state PET is colorless and crystal clear, when heated or cool down the filament changes its transparency, having a more crystalline structure when allowed to cool down slowly. There are different versions of PET, for example, PETG is clear thermoplastic and it is possible to mold the object after printed. PET has a wide temp range - 160°C to 210°C. PET needs to be stored in a dry place.
Wood Filament, contains a mixture of recycled wood and binding polymer. When printing objects with different temperatures prints will have different shades of brown wooden-like surface. The higher the temp used during printing the result will be a darker brown. Changing printing temp while printing can create a tree’s growth ring effect.
Nylon known for its biocompatibility is widely used in cartilage replacements and prosthetics. Most popular are Nylon 618, natural white color, and Nylon 645, fairly clear. Nylon, in general, has great self-bonding properties. A great feature of Nylon 618 is that you can dye it in a color and shade you want. It is recommend to print first and then dye. You can try to change the color of the filament first and then print which is especially convenient if you’d like to have a multicolor object.
HIPS filament is made from a High Impact Polystyrene. This filament is bright white in color and biodegradable therefore there are no adverse effect when placed in contact with humans or animals. HIPS filaments have curling and adhesion problems, which can be reduced by using a heated bed during printing. As published in the 3DPPVD blog, HIPS filament can also be used as support structure while printing and then dissolved in a colorless liquid hydrocarbon called Limonene.
The applications for 3D printing are limitless. Innovators are constantly coming up with new applications and designs for the technology; however, one of the main limitations to desktop FFF 3D printing’s use is often a filament’s material properties. Kai Parthy has been a powerhouse when it comes to inventing new fused-filament deposition materials, inventing LayWoo-d3, […]
