METHOD OF MANUFACTURING A STIFF ENGINEERED COMPOSITE
The method of making a compressed biocomposite body includes compressing a mass of biocomposite material comprised of discrete particles and a network of interconnected glucan-containing mycelia cells in the presence of heat and moisture into a compressed body having a density in excess of 18 pcf. Compression may take place batch wise in a press or continuously in a path of narrowing cross-section defined by a series of heated rollers.
Method and device for in situ marking a workpiece in a thermal forming process
A method for marking a workpiece (6) uses a device, wherein the workpiece (6) is formed at least partially in a thermal master or forming process, comprises a surface (10) directed towards the workpiece (6), wherein a number of individually controllable heating elements (2) is distributed behind the surface (10) for a local heating of a workpiece surface portion. Each of the heating elements (2) comprises a solid material (11) having a surface structure and a heating structure (3), wherein the surface (10) directed towards the workpiece (6) encompassing the surface structures (40) has a uniform smooth surface allowing to dark, burn or foam the surface (7) of the workpiece (6) through heat introduction.
Forming apparatus, shaped object manufacturing method, and conveyance apparatus
A forming apparatus is equipped with (i) a conveyance unit configured to convey a formation sheet, that expands due to irradiation with electromagnetic waves, along a conveyance path in a state in which tension for causing bending in accordance with a conveyance path that is convexly bent is applied, and (ii) an irradiation unit configured to irradiate with the electromagnetic waves the formation sheet during conveyance by the conveyance unit in the state in which the tension is applied.
