Stereolithography is one of the many methods of 3D printing. It is one of the earliest 3D printing method, introduced in 1984 by Chuck Hull and patented in 1986. Simply put, Stereolithography Apparatus (SLA) is a 3D printing machine that converts liquid plastic into solid objects using various steps and procedures, which we will go through in this post.Stereolithography was patented as a rapid pro...read more

Selective Laser Sintering (SLS) is an Additive Manufacturing process that works on the principle of Power Bed Fusion. It was developed and patented by Dr. Carl Deckard and Dr. Joe Beaman at the University of Texas in the 1980s. SLS is a widely used 3D printing method and we will look into the qualities and characteristics that makes it stand out.How it Works?SLS works on the power bed fusion proce...read more

Selective Laser Melting (SLM) is an additive manufacturing process that is used to produce metal parts. It was first started in 1995 at the Fraunhofer Institute ILT in Germany. This 3D printing method is very similar to Selective Laser Sintering (SLS) as both methods create parts layer-by-layer and fuse them, with the most significant difference being the material used. SLS require polymer powder ...read more

PolyJet is a 3D printing technology that allows us to produce smooth and detailed objects with high accuracy. It is also called Material Jetting and was developed back in 1998 by Israeli 3D printer manufacturer Objet Geometries. PolyJet is considered to be one of the most accurate 3D printing technology with accuracy of up to 0.016 mm which allows it to create highly detailed as well as complex ge...read more

Multi Jet Fusion or MJF is a 3D printing process introduced by HP in 2016. This is one of the newer additive manufacturing processes design for industrial and commercial production. It combines technologies and techniques of various older 3D printing methods, such as SLS and PolyJet, to improve the overall quality and characteristics of the parts printed. MJF promises better printing time, mechani...read more

FDM, or Fused Deposition Modelling, is a layer additive manufacturing process where the print material, or filament, are put together layer by layer in a specific sequence. This sequence is determined by the shape of the desired part, which is provided using CAD designs and STL files.FDM was introduced by S. Scott Crump in 1988. The term ‘Fused Deposition Modelling’ is trademarked by S...read more

Electron Beam Melting, or EBM, is a metal additive manufacturing method. It is one of the main methods used for printing 3D part although SLM/DMLS are more popular. EBM comes under the umbrella of Power Bed Fusion in which powder material are fused together using concentrated energy beams. This method is mainly used by Arcam in their 3D printers. Arcam was bought by General Electric (GE) so these ...read more

Digital Light Synthesis, or DLS, is a 3D printing method that was introduced by Carbon Inc. This additive manufacturing method is similar to DLP and SLA methods as it uses prints parts by curing resins using a light source. However, it comes with certain advantages and uses some unique techniques which aims at making this method better than others. Let us look into what are they, the printing proc...read more

Digital Light Processing, or DLP, is an additive manufacturing process. It is a type of vat polymerization, which means it uses a vat or tank to hold the photopolymer and light is used to cure the photopolymer/resin accordingly. This process is very similar to SLA (Stereolithography) which is also a type of vat polymerization.Let us find out how DLP works, what are its advantages and disadvantages...read more

Binder Jetting is an additive manufacturing process which was developed in 1993. It is primarily used for printing parts using metal, ceramic and can also be used to print sand-moulds for casting. In binder jetting, a liquid binder is selectively deposited on a powder bed (can also be called the build platform) using a print head. Let us dive into its working and what benefits it has over other me...read more
