Schematic Diagram of Solid Ground Curing Process. Solid ground curing utilizes the general process of hardening of photopolymers by a complete lighting and hardening of the entire surface, using specially prepared masks. [6] In SGC process, each layer of the prototype is cured by exposing to an ultra violet (UV) lamp instead of by laser scanning.
While the usage of a binding agent allows for high melting temperature (e.g. ceramic) and heat-sensitive (e.g. polymer) materials to be powdered and used for additive manufacturing, binder jetting parts require additional post-processing that can require more time than it takes to print the part, such as curing, sintering, and additional ...
Continuous Liquid Interface Production (CLIP; originally Continuous Liquid Interphase Printing) is a proprietary method of 3D printing that uses photo polymerization to create smooth-sided solid objects of a wide variety of shapes using resins.
An SLS machine being used at the Centro de Pesquisas Renato Archer in Brazil.. Selective laser sintering (SLS) is an additive manufacturing (AM) technique that uses a laser as the power and heat source to sinter powdered material (typically nylon or polyamide), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure.
The content of magnesium is greater than that of silicon, otherwise they belong to the aluminum–silicon–magnesium alloys (AlSiMg). AlMgSi is one of the hardenable aluminum alloys, i.e. those that can become firmer and harder through heat treatment. This curing is largely based on the excretion of magnesium silicide (Mg 2 Si). The AlMgSi ...
The ASTM International F42 standards committee has grouped selective laser melting into the category of "laser sintering", although this is an acknowledged misnomer because the process fully melts the metal into a solid homogeneous fully dense mass, unlike selective laser sintering (SLS) which is a true sintering process. Another name for ...
AuAl 2 is the most thermally stable species of the Au–Al intermetallic compounds, with a melting point of 1060 °C (see phase diagram), which is similar to the melting point of pure gold. AuAl 2 can react with Au, therefore is often replaced by Au 2 Al, a tan-colored substance, which forms at composition of 93% of Au and 7% of Al by mass.
Melting is not the formation mechanism. Instead, metals are joined in the solid-state via disruption of surface oxide films between the metals, i.e. ultrasonic metal welding mechanisms. [3] [4] CNC contour milling is used interchangeably with the additive stage of the process to introduce internal features and add detail to the metal part.
