3D printing technologies

Arthur Georges Joel Mamou-Mani, AAdip ARB/RIBA FRSA (born 5 February 1983 in Paris) is a French architect. Mamou-Mani is director of the architecture and design practice Mamou-Mani Ltd which specializes in a new kind of pop-up, digital fabrication led architecture.

Stereolithography (SLA or SL; also known as vat photopolymerisation, optical fabrication, photo-solidification, or resin printing) is a form of 3D printing technology used for creating models, prototypes, patterns, and production parts in a layer by layer fashion using photochemical processes by which light causes chemical monomers and oligomers to cross-link together to form polymers. Those polymers then make up the body of a three-dimensional solid. Research in the area had been conducted during the 1970s, but the term was coined by Chuck Hull in 1984 when he applied for a patent on the process, which was granted in 1986. Stereolithography can be used to create prototypes for products in development, medical models, and computer hardware, as well as in many other applications. While stereolithography is fast and can produce almost any design, it can be expensive.

3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.

3D makeR Technologies (makeR) is a 3D printer manufacturer. The company started out as an open-source printer company. It was founded between Barcelona and Santa Marta by Carlos Camargo, who currently acts as the CEO of the company. Following the traditional RepRap model, the makeR's first products were as do it yourself kits with an alternative version based on open-source FDM 3D printer Prusa i3, called Prusa Tairona. Current makeR 3D printers are designed with a closed frame and selected build sizes.

Desktop Metal, Inc. is a public American technology company that designs and markets 3D printing systems. Headquartered in Burlington, Massachusetts, the company has raised $438 million in venture funding since its founding from investors such as Google Ventures, BMW, and Ford Motor Company. Desktop Metal launched its first two products in April 2017: the Studio System, a metal 3D printing system catered to engineers and small production runs, and the Production System, intended for manufacturers and large-scale printing. In November 2019, the company launched two new printer systems: the Shop System for machine shops, and the Fiber industrial-grade composites printer for automated fiber placement. The World Economic Forum named Desktop Metal a Technology Pioneer in 2017.

ZYYX is a Swedish desktop 3D printer, designed primarily for office and educational applications. Originally launched in 2014 by Magicfirm Europe AB, based at Chalmers Innovation in Gothenburg, the ZYYX 3D Printer is based on FFF technology and features include an automated levelling function, smell-free operation (most 3D printers tend to smell heavily of hot plastic) and an extruder head which is less prone to jamming.

Robocasting (also known as robotic material extrusion) is an additive manufacturing technique analogous to Direct Ink Writing and other extrusion-based 3D-printing techniques in which a filament of a paste-like material is extruded from a small nozzle while the nozzle is moved across a platform. The object is thus built by printing the required shape layer by layer. The technique was first developed in the United States in 1996 as a method to allow geometrically complex ceramic green bodies to be produced by additive manufacturing. In robocasting, a 3D CAD model is divided up into layers in a similar manner to other additive manufacturing techniques. The material (typically a ceramic slurry) is then extruded through a small nozzle as the nozzle's position is controlled, drawing out the shape of each layer of the CAD model. The material exits the nozzle in a liquid-like state but retains its shape immediately, exploiting the rheological property of shear thinning. It is distinct from fused deposition modelling as it does not rely on the solidification or drying to retain its shape after extrusion.

Ultimaker is a 3D printer-manufacturing company based in the Netherlands, with offices and assembly lines in the US. They make fused filament fabrication 3D printers, develop 3D printing software, and sell branded 3D printing materials. Their product line includes the Ultimaker S5 and S3, Ultimaker 3 series, Ultimaker 2+ series and Ultimaker Original+. These products are used by industries such as automotive, architecture, healthcare, education, and small scale manufacturing.

Laser sintering of gold is a jewellery manufacturing technique first developed by Towe Norlén and Lena Thorsson.

Solid ground curing (SGC) is a photo-polymer-based additive manufacturing (or 3D printing) technology used for producing models, prototypes, patterns, and production parts, in which the production of the layer geometry is carried out by means of a high-powered UV lamp through a mask. As the basis of solid ground curing is the exposure of each layer of the model by means of a lamp through a mask, the processing time for the generation of a layer is independent of the complexity of the layer. SGC was developed and commercialized by Cubital Ltd. of Israel in 1986 in the alternative name of Solider System.
