MicroCare solvent smooths out steps left during additive manufacturing processes

Plastic 3D-printed parts are made from ultrathin layers of special polymers built up layer by layer. The process often yields a printed part with a stepped, or terraced, surface that requires smoothing during a postprocessing operation.

Traditional methods of smoothing steps have been time-intensive, manual processes like grinding, buffing, or sandblasting.

Today, however, smoothing fluids are available for use in vapor degreasers. One is MicroCare’s SSF (Smoothing Station Fluid. Immersing unfinished AM parts in the fast-evaporating solvent precisely removes the steps. Because the fluid slightly melts the surface of the plastic, it is necessary to understand the chemical composition of the 3D-printed polymer and use the correct chemical solution to ensure success.

Trained vapor degreasing experts have experience selecting the best smoothing fluid for the specific type of 3D-printed polymer and can guide part designers through the process.

MicroCare also offers Tergo MCF (Metal Cleaning Fluid), which is used to chemically debind metal parts created via binder jetting.

MicroCare’s SSF (Smoothing Station Fluid) is a nonflammable solvent used to remove slight surface irregularities in thermoplastic components produced by 3D printing. The fluid is usable with standard vapor degreasers and AM systems.
