1974 David E. H. Jones first wrote about the idea of 3D printing in the journal New Scientist 1984 Alain Le Méhauté and others filed a patent for stereolithography(a laser-based 3D printer). 1989: S. Scott Crumpdeveloped FDM. It is the technology used by most 3D printers today. 1992The first FDM machine was sold in 1992 by S. Scott Crump's company,...
Modelling
The first step in 3D printing something is to make it on a computer. People do this with CAD (Computer Aided Design) software or a 3D scanner. To design models[permanent dead link]in CAD, people start with basic shapes, and build from that point. 3D scanners are machines that take lots of measurements of the object and automatically make a model on the computer. They can be very fast, but are also more expensive. CAD models are usually saved on computers as STLfiles. They are saved as lots of...
Printing
There are a lot of different ways that 3D printers work. There are also many different materials that can be used. Every method and material has its advantages and disadvantages. The main things to think about when choosing a machine are usually speed, costs, and color. Printers that work directly with metals are generally expensive. However less expensive printers can be used to make a mold, which is then used to make metal parts. Typical layers are around 100 μm thick, or about one tenth th...
Finishing
After the machine has finished printing, sometimes people finishthe model. This means making small fixes to make it look better. Finishing includes taking off material that the printer placed to support the model. This sometimes can take a lot of time. There are ways to make it quicker, but it is often easiest to remove plastic by hand.

Lots of people are trying to develop cheap 3D printers for people to use at home. Libraries have also started to buy smaller 3D printers so that people can learn about them without having to buy one. Lots of work has been done by DIY communities, as well as schools and hacker communities. By 2017, more people were starting to use 3D printing in their own home for small items such as gearsand small decorations.
Medical
3D printing is used to make medical supplies cheaply. People think that the two biggest uses will be making hearing aids and false teeth In March 2014, surgeons in Swansea used 3D printed parts to rebuild the face of a motorcyclist who had been badly injured in a road accident.[source?]
Manufacturing
In 2014, a supercar was made by a Swedish company that utilizes many 3D printed components. Urbeewas the first car in the world to have its bodywork and windows 3D printed. In 2015, a Royal Air Force Eurofighter Typhoon fighter jet flew with 3D printed parts. The United States Air Force has begun to work with 3D printers, and the Israeli Air Forcehas also purchased a 3D printer to print spare parts.
3d printers do produce noise as its operation involves a lot of vibration. The University of Michigan shown how much sound does a 3d printer may produce. Their research shows that sounds more than 85 DB is harmful for human. However, the good 3d printers with silent motherboard may limit the noise up to 55 DB. Still there are plenty of manufacturer...
Types of 3D printing processes. There are many different 3D printing processes, that can be grouped into seven categories: Vat photopolymerization; Material jetting; Binder jetting; Powder bed fusion; Material extrusion; Directed energy deposition; Sheet lamination; Each process and piece of equipment has pros and cons associated with it.
In recent years, 3D printing has developed significantly and can now perform crucial roles in many applications, with the most common applications being manufacturing, medicine, architecture, custom art and design, and can vary from fully functional to purely aesthetic applications. 3D printed chocolate.
Feb 20, 2024 · Learn how 3D printing evolved from a layer-by-layer process invented by Chuck Hull in 1984 to a versatile and accessible technology for various applications. Explore the key milestones, innovations, and challenges in the timeline of 3D printing history.
3D printing filament is the thermoplastic feedstock for fused deposition modeling 3D printers. There are many types of filament available with different properties. [1] Filament comes in a range of diameters, most commonly 1.75 mm and 2.85 mm, [2] with the latter often being confused with the less common 3 mm. [3]
May 19, 2024 · 3D printing, in manufacturing, any of several processes for fabricating three-dimensional objects by layering two-dimensional cross sections sequentially, one on top of another. The process is analogous to the fusing of ink or toner onto paper in a printer.
