When did the SLA patent expire?
Expiring Date: December 20, 2016 Other patents set to expire this year include 3 patents from 3D Systems (all SLA methods) and 6 from Stratasys which involve FDM, support removal, and optimization. The technology behind all of these patents promises to be an incredible boon for the development of 3D printing.
Who owns the patent for 3D printing?

Are there any existing patents for the 3D printer?
It looks like 106 patents have expired, with 3D systems granted the first patent for stereolithography.
What company has the most 3D printing patents?
Manufacturers file the most patents With respect to additive manufacturing, HP filed the most patents in 2020 – 470 to be precise, followed closely by General Electric with 331 patents.
When did 3D printing patent expire?
After 20 years, in 2009, that FDM patent expired and what came next is often considered the birth of mainstream consumer 3D printing via the RepRap Project led by Dr.
In what decade did most 3D printing patents expire?
From 2002 to 2014, about 225 early 3D printing patents expired. About 16 key patents relating to 3D printing processes called Material Extrusion, Powder Bed Fusion, and Vat Photopolymerization expired in 2013-14. This means that 3D printing technology that is at least 20 years old is now available for anyone to use.
When did 3D printing start?
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.
How long is a patent?
A U.S. utility patent, explained above, is generally granted for 20 years from the date the patent application is filed; however, periodic fees are required to maintain the enforceability of the patent.
Is 3D printing legal?
The current IP rights that 3D printing may have an impact on, are copyright, patent and, most importantly, design rights. Under the copyright law, a 3D CAD file (but not a 3D scan from an existing object) can fall under copyright regime, as it covers technical drawings, diagrams and models.
Where do I see my patents in Iprms?
All you have to do in this case is click the “Application Status” tab, which is near the top of the search page next to the “Patent search” and “Patent E-register” pages.
What did 3D Systems invent?
Hull’s company, 3D Systems Corporation, released the world’s first stereolithographic apparatus (SLA) machine, the SLA-1, in 1987. This machine made it possible to fabricate complex parts, layer by layer, in a fraction of the time it would normally take.
What is stereolithography 3D printing?
Stereolithography (SLA) is an industrial 3D printing process used to create concept models, cosmetic prototypes, and complex parts with intricate geometries in as fast as 1 day.
Is 3D printing the future?
While 3D printing may not be taking over the entire manufacturing industry just yet, analysts predict there will be a great deal of growth and the market will be worth 32.78 billion USD by 2023. Analysts have predicted the 3D printing industry will be worth 32.7 billion USD by 2023.
Is 3D printing worth investing in?
3D printers are a worthy investment if you take the time to learn the process thoroughly and act on the information. Have a plan and you can save, as well as make money with 3D printing. Everyone has the potential to make it a worthy investment.
Who invented 3D printing?
Charles Hull is the inventor of stereolithography, the first commercial rapid prototyping technology commonly known as 3D printing. The earliest applications were in research and development labs and tool rooms, but today 3D printing applications are seemingly endless.4 days ago.
Do technology patents expire?
Eventually, patents do expire. While a patent will remain in force for a period of time, eventually it is considered to be no longer in effect. The patented invention then becomes freely usable by others. Patent terms, if maintained correctly, vary but generally go for up to 20 years.
In which year SLS is patented?
Rapid Prototyping of Ceramics 7). FIGURE 7. CAD file of a craniofacial implant (3D Ceram, Limoges, France). Since being patented in 1989, the SLS technology has become one of the most used processes for prototyping and product development in all industries.
Are printers patented?
Printing patents were independent of the private copyright system established by the Stationers’ Company, even though most printing patents were granted to members of the Company. The importance of printing privileges decreased over time, but they still existed after the Statute of Anne was enacted.
What materials were originally used to make 3D printers?
The earliest printed patented material was a Hot melt type ink for printing patterns using a heated metal alloy. See 1970’s history above. Charles Hull filed the first patent on August 8, 1984, to use a UV-cured acrylic resin using a UV masked light source at UVP Corp to build a simple model.
How was the 3D printer originally made?
The earliest record of 3D printing through the additive process was the Japanese inventor Hideo Kodama in 1981. He created a product that used ultraviolet lights to harden polymers and create solid objects. The object is printed layer by layer, rinsed with a solvent, and hardened with an ultraviolet light.
What does a patent do?
A patent is the granting of a property right by a sovereign authority to an inventor. This grant provides the inventor exclusive rights to the patented process, design, or invention for a designated period in exchange for a comprehensive disclosure of the invention.
