Types of 3D Printers: “The real voyage of discovery consists not in seeking new landscapes, but in having new eyes.” – Marcel Proust. This quote shows the exciting journey you’ll take with 3D printers. You’ll learn how these machines change industries by making quick prototypes, detailed designs, and custom products.
Exploring 3D printing, you’ll find many types of printers. Each has special skills and uses. From FDM to SLA, and SLS to DLP, there’s a printer for every need. For example, SLA printers like the Form 3+ can make very precise designs with a laser spot size of 85 microns and XY resolution of 25 microns.
DLP printers have XY resolutions between 35 and 100 microns, making them great for detailed work. Most resin printers can build layers as thin as 25 to 200 microns vertically. This shows how each type of printer is made for a special job, like making complex shapes or useful prototypes.
Resin 3D printers are top-notch for making things with fine details, like jewelry or models, with resolutions as small as 25 microns. They work with many materials, from castable to engineering resins, making them good for many projects.
The history of 3D printing is filled with big steps forward. It started in 1981 when Dr. Hideo Kodama made a machine that used UV light to make resin solid4. This early work led to big changes in stereolithography and other 3D printing methods.
In 1986, Chuck Hull changed the game with the first SLA patent and the .stl file format. Two years later, Hull founded 3D Systems Corporation and released the SLA-1 printer. This printer made SLA technology real and useful.
SLA uses a UV laser to make resin solid layer by layer. This turns digital designs into real objects.
After Hull’s breakthrough, 3D printing tech quickly grew. In 1988, Carl Deckard patented SLS, which uses a laser to make solid structures from powder. Around the same time, Scott Crump created FDM, which became popular for home use by Stratasys.
These technologies made 3D printing better for work and medicine.
“In 2005, the RepRap Project, started by Dr. Adrian Bowyer, aimed to make 3D printing cheaper and more accessible”.
By the late 2000s and early 2010s, new patents let innovation speed up. For example, when FDM patents expired in 2009, affordable 3D printers like MakerBot became popular. This time also saw new materials like carbon fiber and glass fiber in 3D printing.
