3-D printing might be a recent phenomenon but it has definitely changed the world of manufacturing. From simply allowing individuals to design and make their own items at home, all the way to ...
A 3D-printed firearm is a firearm that is partially or primarily produced with a 3D printer. While plastic printed firearms are associated with improvised firearms, ...
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 ...
Josef Průša was a core developer of the RepRap project who had previously developed a PCB heated "print bed". He adapted and simplified the RepRap Mendel design, reducing the time to print 3D plastic parts from 20 to 10 hours, changing to the use of two Z-axis motors to simplify the frame, and including 3D printed bushings in place of regular bearings.
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.
Terran 1 was an expendable two-stage small-lift launch vehicle developed by Relativity Space.Development began in 2017 and the rocket was retired in 2023. [2] Most structures and components of the vehicle are manufactured with 3D printing processes.
The ABS part being printed will not detach from the build platform as it cools and shrinks, a common cause of print failure by warping of the part. [19] A more durable alternative is to use a polyetherimide surface. [20] Researchers have devised a method to 3D-print polyimide material including Kapton. [21]
Some important 3D printer metrics include: Print technology: 3D printing processes encompasses a variety of methods which each have their own unique challenges. Length of production run and support: 3D printers often require adjustments and parts replacement. A long production run often means that spare parts are also available.
