Whiteprinting replaced the blueprint process for reproducing architectural and engineering drawings because the process was simpler and involved fewer toxic chemicals. A blue-line print is not permanent and will fade if exposed to light for weeks or months, but a drawing print that lasts only a few months is sufficient for many purposes.
PLA objects can be fabricated by 3D printing, casting, injection moulding, extrusion, machining, and solvent welding. PLA filament for use in 3D printing. PLA is used as a feedstock material in desktop fused filament fabrication by 3D printers, such as RepRap printers. [39] [40] PLA can be solvent welded using dichloromethane. [41]
Art Instruction, Inc. was known to many aspiring artists as the Draw Me! School , because of the familiar "Talent Test" advertising campaigns seen in magazine ads, matchbook covers with Spunky the Donkey, TV commercials and online promotions with the "Draw Me!"
By introducing controlled levels of moisture to ExOne 316L powder prior to printing, the study shows enhanced binder absorption and reduced particle agglomeration, resulting in higher-quality multi-layered parts. This approach improves key factors such as surface roughness, line formation, and porosity control.

A desktop FFF printer made by Stratasys. Fused deposition modeling was developed by S. Scott Crump, co-founder of Stratasys, in 1988. [6] [7] With the 2009 expiration of the patent on this technology, [8] people could use this type of printing without paying Stratasys for the right to do so, opening up commercial, DIY, and open-source 3D printer applications.
PLA schematic example. A programmable logic array (PLA) is a kind of programmable logic device used to implement combinational logic circuits.The PLA has a set of programmable AND gate planes, which link to a set of programmable OR gate planes, which can then be conditionally complemented to produce an output.
A draw sheet is a small bed sheet placed crosswise over the middle of the bottom sheet of a mattress to cover the area between the person's upper back and thighs, often used by medical professionals to move patients. It can be made of plastic, rubber, or cotton, and is about half the size of a regular sheet.
