HISTORY of 3D Printing
Transcript of HISTORY of 3D Printing
Scott Crump invented this type of printing in the late '80s. The material is fed through a nozzle and "writes" the material onto the build platform. The build platform lowers and the nozzle moves and writes the next layer.
Fused Deposition Modeling (FDM)
Chuck Hull created this oldest type of commercial 3D printing. Liquid resin in a vat has a laser shot into it. The build platform lowers, and the laser shoots in again, hardening another layer until every layer of the product is finished. Then it is washed in a chemical bath and put in a UV oven.
Laser Sintering (SLS)
Carl Deckard created this technology about the same time as SLA. Powder particles are spread on a build platform, are fused together with a laser, then the powder is spread out again over the build platform, then it lowers for the next layer.
Plastic, metal and ceramic/sand powder
The first functional kidney is printed.
The first 3D printed organ is implanted into a human. A urinary bladder made from the patient's own cells. Shows more of the many possibilities of the 3D printer.
RepRap is created. Their goal: to create a printer that can print most of its own components
First 3D printed prosthetic leg is used.
First 3D printed gun.
Nike releases the first cleat to be worn by football players - Viper Laser Talon
Charles Hull creates the first stereolithography 3D printer. A 3D digital model can be printed into a tangible 3D object. Used mainly for the production of prototypes before mass production of an object.
The first stereolithograpic apparatus is made. UV laser solidifies the liquid material layer by layer to create the 3D object. Not perfected, but complicated parts can be produced quickly.
T I M E L I N E
Created at MIT in 1993. Powder from a moving nozzle is stuck together on a build platform, a wiper re-distributes the powder, and the nozzle sticks more of the powder together.
Plaster, ceramic, metal, glass
Three Dimensional Printing (3DP)
This technology is only seen in Object Geometries. Droplets of the material are dropped onto the build platform, then UV light cures it. Then the platform lowers for the next layer.
V I D E O
Maker Bot introduces its DIY 3D printer. Most anybody can purchase a 3D printer.
First blood vessel is printed.
First 3D printed robotic aircraft and car.
Gold and silver are now 3D printable.
First 3D printed jaw is implanted.
Started in 1997 by Acram. Powder on a build platform is fused together by an electronic beam, the platform lowers, and a wiper re-distributes the powder.
Developed by Helisys. Thin sheets of material are cut by a knife or a laser and glued onto the sheet of material that was just cut.
