To make complex ceramic components, double-head extrusion was used to print two materials: one to form the main part and another to form the support structure. Sintering of ceramic materials is the method involving consolidation of ceramic powder particles by heating the “green” compact part to a high temperature below the melting point, when the material of the separate particles diffuse to the neighboring powder particles. Sintering methods commonly include atmospheric pressure sintering, hot pressing, hot isostatic pressing, and so on. Here, to investigate the sinterability and sintering shrinkage of the extrusion-based 3D-printed green bodies, we used the atmospheric pressure sintering to sinter 3D-printed ceramic samples.Ceramic Paste is a partially synthetic, metal-free universal paste which has been formulated for the most demanding applications. The combination of a partially synthetic base oil, a mature additive technology and the most state-of-the-art solid lubricants from the area of high-tech ceramics has produced a high performance paste for universal use.

[ Google Scholar] For the air cooling low- and high-tension tests, we used a large Noctua NH-D15 air cooler. We created the low tension mount environment by torquing the mounting screws to 1.13 Nm (10 in/lbs). Specified for automotive, appliance and assembly industries for bonding, insulating and coating applications. Audi (and most manufacturers) have very specific requirements for materials designed to be used with their parts. I would be very cautious about going with the "latest and greatest". For example, there was a time when applying copper paste was quite common for spark plugs, but today almost every plug supplier will advise against it since the threads are already pre-coated with a lubricant. Also, the addition of lubricants can throw off the torque values for fasteners.

Many clay-based ceramic materials are hard, porous, and brittle. The study and development of ceramics includes methods to deal with these characteristics, to accentuate the strengths of the materials and investigate novel applications.

[ Google Scholar] [ CrossRef] There are thousands of possible refinements of this process. Some of the most common involve pressing the green body to give the densification a head start and reduce the sintering time needed. Sometimes organic binders such as polyvinyl alcohol are added to hold the green body together; these burn out during the firing (at 200–350°C). Sometimes organic lubricants are added during pressing to increase densification. It is not uncommon to combine these, and add binders and lubricants to a powder, then press. (The formulation of these organic chemical additives is an art in itself. This is particularly important in the manufacture of high performance ceramics such as those used by the billions for electronics, in capacitors, inductors, sensors, etc. The specialized formulations most commonly used in electronics are detailed in the book "Tape Casting," by R.E. Mistler, et al., Amer. Ceramic Soc. [Westerville, Ohio], 2000.)
