In addition to volumetric color by use of multiple print heads and colored binder, the 3D printing process is generally faster than other additive manufacturing technologies such as fused deposition modeling material jetting which require 100% of build and support material to be deposited at the desired resolution. In 3D printing, the bulk of ...
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 ...
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 ...
An analysis of 3D printing construction in remote areas [120] as an alternative to conventional construction reveals significant potential. 3D printing in construction offers innovative solutions to the unique challenges of these locations. The ability to use local materials, reduce waste, and adapt to complex and customized designs are just a ...
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 ...
Two-dimensional culture also suffers from poor diffusivity of nutrients and gases, requiring added media and supplements to be manually evenly distributed, and may result in irreproducible data. [ 1 ] [ 2 ] Microcarrier cell suspensions in stirred tank bioreactors allows for an even distribution through homogenous stirring. [ 1 ]
