The rest of the process is done in a furnace, usually with a first step to burn the plastic away and a second hotter step to sinter (cook and bind) the particles togheter. This requires extremely high temps, between 500° and 1500°, depending on the material. • Clay • Basalt ...
The idea is pretty simple actually: if you print a hot plastic material on a Cold/semi-cold surface the plastic is going to contract which is going to lead to distortions or the printed object might pop off entirely. You do not want to keep the layers molten though as it must be able...
develops polymeric ("plastic") materials for industrial uses. Connecting individual polymer molecules by cross-links (red) increases the strength of the material. Thus ordinary polyethylene is a fairly soft material with a low melting point, but the cross-linked form is more rigid and resistent ...
Achieving a sufficient balance of matrix and fibre reinforcement is key to the functionality of ACCs, and the volume of matrix present after processing relies on how much cellulosic material dissolves, as well as how much is retained under compaction. In previous work, it was hypothesised that a...
Moreover, solid-state plastic crystal electrolytes, known for their high ionic conductivity at RT, have been identified as promising interlayers to address interfacial challenges [113, 114]. For instance, the succinonitrile (SN)-based plastic crystal electrolyte (PCE) interlayer (Fig. 7B) offers ...

To avoid tearing of the PDMS frame upon peeling the plastic mould, we had to reduce the affinity between PDMS and the crosslinked resin. Three pos- sibilities work equally: 1/ Glycerol coating by dipping; 2/ hydrophobization using Trichloro(1 H,1 H,2 H, 2H-perfluorooctyl)silane ...
While some types of metals--such as aluminum--can meet all of the above requirements, no single plastic material is known to us that meets all of requirements 1 through 6(a) or 6(b) and 7-8; hence, a non-metalli
The software determined the point in time when G′, storage modulus, crossed G″, the loss modulus, i.e., G′=G″ at this point. This time was then added to the time it took to get the material in the instrument and that overall time was considered the onset of cure. This point ...
