How did additive manufacturing start?
In 1980, Dr. Hideo Kodama filed the first additive manufacturing patent. The researcher at the Nagoya Municipal Industrial Research Institute was looking for a system to create photopolymer prototypes. Kodama wanted to use a container of photopolymer material, exposed to ultraviolet light, to harden a part.
Was the first modern additive manufacturing technique?
The oldest fully realised additive manufacturing technique is stereolithography, which was developed in 1987 by 3D Systems. The system works with a lithograph printer that uses UV light and a laser to solidify thin layers of liquid polymer to create three-dimensional objects.
When was 3D printing invented?
The first documented iterations of 3D printing can be traced back to the early 1980s in Japan. In 1981, Hideo Kodama was trying to find a way to develop a rapid prototyping system. He came up with a layer-by-layer approach for manufacturing, using a photosensitive resin that was polymerized by UV light.

Who first patented 3D printing?
Charles HullThe first patent for a 3D printer was issued to Charles Hull for "Apparatus for Production of Three-dimensional Objects by Stereolithography" in 1986.
Is 3D printing faster than manufacturing?
More speed – For small to medium runs of small objects, 3D printing is already faster than many methods of traditional manufacturing simply because of the time it takes to create the tooling for injection molds and casts required for traditional manufacturing.
Who is the leader in 3D printing?
5 Biggest 3D Printing Companies#1 3D Systems Corp. (DDD)#2 Proto Labs Inc. (PRLB)#3 FARO Technologies Inc. (FARO)#4 Materialise NV (MTLS)#5 The ExOne Co. (XONE)
Why was 3D printing originally developed?
That prestigious honor goes to engineer Chuck Hull, who designed and created the first 3D printer in 1984. He had been working for a company that used UV lamps to fashion tough, durable coatings for tables when he hit on the idea to take advantage of ultraviolet technology to make small prototypes.
How long have we used additive manufacturing in industry?
The first additive manufacturing system appeared in the 1980s — from there, additive manufacturing has taken off, branching out into several different types of technologies for turning CAD files into 3D physical objects.
What is the difference between AM and CNC?
While AM can be used to make fairly strong prototypes, the mechanical advantages of CNC are significant. The extruded metal blank is physically consistent and requires no adhesion between layers. It is a solid block, and it can, therefore, be used to make strong, rugged prototypes with minimal deformities.
Where is additive manufacturing used?
Common applications include environmental control systems (ECS) ducting, custom cosmetic aircraft interior components, rocket engines components, combustor liners, tooling for composites, oil and fuel tanks and UAV components. 3D printing delivers complex, consolidated parts with high strength.
What is additive manufacturing Wikipedia?
Additive manufacturing is defined as a material joining process, whereby a product can be directly fabricated from its 3D model, usually layer upon layer. Comparing to traditional manufacturing technologies such as CNC machining or casting, AM processes have several unique capabilities.
When was additive manufacturing invented?
History of additive manufacturing started in the 1980s in Japan. Stereolithography was invented first in 1983. After that tens of other techniques were invented under the common name 3D printing. When stereolithography was invented rapid prototyping did not exists.
When was stereolithography invented?
Stereolithography was invented first in 1983. After that tens of other techniques... Sample PDF. History of Additive Manufacturing. $37.50. Chapter 2. From Modeling to 3D Printing (pages 25-37) Geometric or 3D modeling playing key role in geometry definition.
When was the first SLS made?
First commercial SLS was in 1990. At the end of 20t century, first bio-printer was developed. Using bio materials, first kidney was 3D printed. Ten years later, first 3D Printer in the kit was launched to the market.
What is additive manufacturing?
Additive Manufacturing is known as the process of adding material to form three dimensional objects. Originally created with rapid prototyping as the goal, it has evolved over the years to span numerous industries and is quickly gaining wider adoption as a manufacturing service that facilitates complex, consolidated end parts and customization on a massive scale. Here is a brief history of how 3D printing technology has developed over the years.
When did 3D printing start?
It wasn’t until the early 1980s, however, that 3D printing technology really began to kick off. Dr. Hideo Kodama from the Nagoya Municipal Industrial Research Institute was the first to invent a layer by layer photopolymer rapid prototyping process.
Why did Charles Hull start 3D printing?
Charles Hull began developing his 3D printing technology in the early 80s because he was frustrated by how time consuming prototyping was back then. Almost 40 years later, 3D printing technology has indeed become the fastest and most cost-efficient way of producing prototypes and has evolved to play important roles in the manufacturing process for many industries. In the past decade, there have been countless innovative projects undertaken using additive manufacturing as the technology continues to develop. Equipment costs have decreased while print quality has increased and the printing process is much faster and more efficient.
What technology was used in the 1980s?
The late 1980s then gave way to a couple more 3D printing technologies still used today: Selective Laser Sintering (SLS), a method which uses a laser beam to melt powder into a solid object, developed by Carl Deckard at the University of Texas in Austin who would later go on to form Stratasys. His early machine “Betsy” was able to print plastic molds for parts. Fused Deposition Modeling, developed by S. Scott Crump & Lisa Crump, was another technology born in the 1980s in which a material is heated and extruded through a nozzle to create an object layer by layer, inspired by the Crumps’ use of a hot glue gun in making their daughter a toy frog. As of 2020, it is the most commonly used 3D printing technology.
When was 3D scanning invented?
As far back as the 1800s, ideas surrounding 3D scanning were taking shape in their own way. In 1859 , Francois Willeme developed a method called “photographic sculpture” in which he could capture 3D models of human subjects using 24 cameras placed at different angles.
Who invented stereolithography?
His method was not commercialized, however, and Charles Hull instead became the first to successfully acquire a patent for his Stereolithography Apparatus and coined the term “stereolithography.”. His method involved building three dimensional objects layer by layer with photopolymers, cured by a UV light beam.
Is printing faster than prototyping?
Equipment costs have decreased while print quality has increased and the printing process is much faster and more efficient. It is now possible to create thicker layers and more accurate, complex shapes than ever before, which has facilitated a shift from prototyping alone to the production of end parts.
When did AM technology start?
The following few decades included continued development of new AM techniques. However, the development of commercially available systems did not occur until 1987. It began with a patent originally owned by UVP Inc. and licensed to Charles Hull, a former employee (Patent 4,575,330). Hull used the patent to form the company 3D Systems. 3D Systems introduced a process that solidified thin layers of ultraviolet light-sensitive liquid polymer using a laser. The SLA-1 was the first commercially available AM system in the world.
When was photosculpture invented?
Around the same time in the 19th century, photosculpture was also invented. In 1860, Francois Willeme simultaneously photographed an object with 24 equally spaced cameras that were located around the circumference of a room. The silhouettes from these photos were then used to create a physical model by carving out 1/24th of it at a time. This was a very labor intensive method, so in 1904, Carlo Baese patented a method that used photographs and graduated light to expose a photosensitive gelatin (Patent 774,549). The gelatin would expand in proportion to the light exposure to create the physical model.
When were topographical maps invented?
AM has a history that can be traced back to the late 19th century and early 20th century with the introduction of layer based topographical maps. In 1982, Joseph E. Blanther patented a manufacturing method to create contour relief maps (Patent 473,901). These maps were created by impressing topographical contour lines on a series of wax plates. The plates were then cut according to the contour lines and stacked on top of each other to create a three-dimensional model that represented the terrain. This gave a rough approximation of terrain that could then be further enhanced by wrapping a paper map over the top of it. Other variants eventually emerged including the use of cardboard or transparent plates as the medium.
How does additive manufacturing work?
Additive manufacturing (AM) technology fundamentally differs from traditional material removal processes like milling, turning, and spark erosion, because this technology family creates metal components by incremental addition of material instead of removal of chips. Starting from a three-dimensional CAD representation of an object, the object is virtually “sliced” into a set of two- dimensional layers. These layers are then successively fused and consolidated on top of each other to recreate the three-dimensional object (Figs. 1.4.14–1.4.16 ).
Why were AM technologies developed?
Over the last decade, metal AM technologies were developed in order to benefit from AM advantages for manufacturing metallic components.
What is AM technology?
AM technologies provide a unique techno-economic profile that complements the capabilities of Traditional Manufacture (TM). Design scenarios exist that directly combine the advantages of both TM and AM technologies such that high-value design outcomes can be achieved at low unit-cost. Examples include the hybrid manufacture of injection moulding tooling and high-value aerospace structures (where TM processes are used where possible to reduce costs and AM processes are used when geometric complexity exceeds TM capability – for example conformal cooling channels manufactured by PBF on billet material) or the addition of out-of-plane geometry by DMD on rolled plate (Chapter, 12, Fig. 4.13F ).
Why are patient specific implants produced with SLM technology?
Due to the unlimited geometric freedom, patient-specific implants are perfectly suited to be produced with SLM technology.
