3D Printed Ceramic is Incredibly Hot Right Now | All3DP

They’ve invented a “pre-ceramic monomer” made from silicon carbide powder, which prints just like any other polymer filament (in a $3,000 incredibly detailed stereolithic system, but still). But when exposed to UV light, the resin cures into a silicon carbide ceramic — which is to say an extremely durable, lightweight, non-conductive material.

After heating at higher temperature (1500-1650 C) silicon carbide lines develop in x-ray diffraction, and fine crystalline regions of silicon carbide and graphite are found in TEM and electron diffraction. XPS shows that silicon-oxygen bonds in the glass are similar

XPS Interpretation of Tantalum

This high-melting point transition metal was separated from niobium in 1802 by A. Ekeberg. When pure, tantalum can be drawn into a fine wire for use as a filament for evaporating metals. Due to its high melting point, ductility, and corrosion resistance, tantalum is often incorporated into a variety of metal alloys for use in chemical process equipment, capacitors and aircraft parts.
