One of the first commercially available products that incorporated the use of Graphene, was a powdered composite used in powder bed inkjet head 3D printing. [8] Composite of Ti-6Al-4V and silver, produced by means of 3D printing and infiltration, SEM picture of metallographic section
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
Research on the health and safety hazards of 3D printing is new and in development due to the recent proliferation of 3D printing devices. In 2017, the European Agency for Safety and Health at Work has published a discussion paper on the processes and materials involved in 3D printing, potential implications of this technology for occupational safety and health and avenues for controlling ...
Control during the flame treatment is critical. Too much of the treatment will degrade the plastic, which will lead to poor adhesion. Too little of a treatment will not modify the surface enough and will also lead to poor adhesion. [7] An additional aspect of flame treatment that must be considered is possible deformation to the adherend.
Polycarbonate is relatively difficult for casual hobbyists to print compared to thermoplastics such as Polylactic acid (PLA) or Acrylonitrile butadiene styrene (ABS) because of the high melting point, difficulty with print bed adhesion, tendency to warp during printing, and tendency to absorb moisture in humid environments. Despite these issues ...
The field of organ printing stemmed from research in the area of stereolithography, the basis for the practice of 3D printing that was invented in 1984. [5] In this early era of 3D printing, it was not possible to create lasting objects because of the material used for the printing process was not durable.
Since TPU is a thermoplastic, it can be melted by the 3D printer's hotend, printed, then cooled into an elastic solid. TPU powders are also used for other 3D printing processes, such as selective laser sintering (SLS) and 3D inkjet printing. It is also used in large vertical injection or extrusion moulding machines to print directly without the ...
Water transfer printing, also known as immersion printing, water transfer imaging, hydro dipping, watermarbling, cubic printing, Hydrographics, or HydroGraphics, is a method of applying printed designs to three-dimensional surfaces. The resulting combinations may be considered decorative art or applied art. The hydrographic process can be used ...
