1K Printing Mortar
1K or "Single component" Print materials are generally slower setting and curing materials which are ideal for large, simple and vertical print geometries.
2K Printing Mortar
2K or "Dual Component" Print Materials are more complex due to the addition of liquid accelerator at the nozzle of the printer. The result of the higher acceleration is a printed bead which can build up quickly and achieve aggressive even 90deg. overhangs*
(*) 90 deg. overhangs are dependant on the particular design geometry.
