BVOH K5 is a support material that dissolves in water much faster. It can be completely dissolved in water or to an easily peelable state in thirty minutes, several times faster than typical PVA materials. Compared with them, it is also less sensitive to humidity. BVOH K5 is a high-quality support material for PLA, PETG, ABS, and TPU, making it applicable to printed products with complex structures.
