The term “3D printing” is generally used synonymously with “additive manufacturing”. This was not always the case, and in 2007 3D printing and 3D printers would have been expressed as extruded materials or plastics for desktop machines. During this time, many industrial users of additive manufacturing adopted the term “additive manufacturing” or RP to refer to processes such as laser sintering or adhesive injection processes. The term 3D printing has become particularly popular in the last decade because of the popularity of desktop printers and the maker movement. Because of its popularity in the media, these terms are now being adopted interchangeably in conversations – especially in marketing materials. Unbeknownst to them, most industrial processes still prefer additive manufacturing or AM. Other terms for 3D printing are additive manufacturing, additive processes, additive technologies, additive layer manufacturing, layer manufacturing, and free-form manufacturing.

Additive manufacturing began in the early 1980s when Dr. HideoKodama applied for the first patent in Japan in 1980, but it was not granted because he did not submit a perfected application within a year. Four years later, in 1984, ChuckHull applied for a patent for stereolithography (SLA). chuckHull went on to found 3DSystems and is the inventor of the STL mesh file format that is still used on most 3D printing platforms. Stereolithography is a process that creates parts based on selectively curing resin layer by layer, creating a cross-section of 3D geometry one at a time. The UV-sensitive resin reacts with the UV laser, causing it to harden where it is subjected to impact.

In 1987, CarlDeckard filed a patent for selective laser sintering, which was later granted in 1989. Selective laser sintering (SLS) is a process that melts fine plastic powder with a laser in a heated build chamber. sLS brings more versatility to end-use products because it uses thermoplastic nylon as its printing material. It was closely followed by the invention of fused deposition modeling (FDM) in 1988 by Stratasys founder S. Scott Crump. The patent was granted in 1992. Also in 1989, EOS was founded. To this day, EOS, Stratasys and 3DSystems remain major players in additive manufacturing.

In the early 1990s and early 2000s, additional technologies were invented and innovated. This encompassed Solidscape’s resin printing for dewax casting, Z-Corporation’s adhesive injection process for sandstone-based parts, the manufacture of paper-based layered objects offered by Helisys and its Arcam metal electron beam melting process. During this time, another major 3D printing process was developed – selective laser melting (SLM).SLM is a combination of direct metal laser sintering (DMLS created by 3DSystems), LaserCusing (the term for ConceptLaser), and direct metal laser melting (DMLM) are synonymous.

Over the past decade, from 2009 to 2019, many of the original patents of 3DSystems, Stratasys and other founding companies have expired. Along with the expiration of key patents, many other 3D printing companies have emerged in the professional, consumer and mid-range “prosumer” 3D printing space. 2011 meant the creation of Formlabs, the maker of the first consumer version of the SLA3D printer. 2013 saw the creation of Markforged, a professional consumable printer capable of embedding continuous carbon or Kevlar fibers between layers for increased stiffness. 2015 saw the launch of DesktopMetal, the first metal 3D printer. DesktopMetal first implemented a metal 3D printer that uses FDM-style extrusion and plasticized metal rods to produce metal parts. At that time, Markforged also produced a system that used a similar method to print metal.

In 2013, MakeXYZ was created to interconnect consumer desktop 3D printers with users who need parts, and Xometry was launched in 2014 to instantly price 3D models for a variety of specialized manufacturing technologies, including additive manufacturing and CNC machining services. leverages partner manufacturing companies to enable manufacturing projects purchased through Xometry’s services.In 2019, Xometry implemented its consumables and finishing services to provide on-demand e-commerce services for manufacturers and partners alike. Bringing MaaS to 3D printing services allows a single space to connect jobs to thousands of capable manufacturers with a large portfolio of capabilities.
