Value of 3D-printing thermoset resin in UL94 V0 flame retardant parts

Although not always visible, flame retardant plastics are used in a wide range of applications. From machine parts, to train parts. From parts for aviation to parts in household electronics and equipment. In many cases you would not know that a special plastic is used in that part. In the basics a very few amount of plastics – often exotic types- are flame retardant, like some grades of polyetherimide (PEI). Other thermoplastics like PP, PA, PC, ABS and HIPS can achieve a good flammability rating when packed with additives.

The most important flammability tests for instance the UL94 and the aviation standards require that the material should self-extinguish within a certain amount and that there are no (burning) drops of plastic fall off the part within a certain time. The last one can be tricky, as a the temperature of a yellow and blue flame will easily rise above 1000°C / 1832°F. At these temperatures all thermoplastics will be melting. Thus the additives have to cool the plastic long enough until the test time of often 20 – 60 seconds passes.

With thermosetting plastics, like all 3D-printing resins are, it is different. These types of resins do not melt. They will straight go to the burning phase at above 400°C. As they will not melt, the parts won’t drip and there is no hazard for flaming drips. Of course the temperature of the flame is above the temperature that a resin can handle. The additives do have a slightly easier job as the degradation temperature of the plastics are higher compared to their thermoplastics counterparts.

Liqcreate Flame Retardant HDT

Liqcreate Flame Retardant HDT is a rigid off-white photopolymer resin and can be processed on most open resin based 3D-printers. 3D-printed parts from this material can withstand high temperatures without posing a fire hazard due to its self-extinguishing capabilities. This material is perfect for creating parts that need to comply with UL94-V0 test standards. Such as interior parts in cars, airplanes, trains and electronic devices. In addition, it can be excellent for tooling manufacturing aids, connector housings and covers.
