Advantages And Disadvantages Of Utilizing Surface Mount Innovation For Pcb Assembly

In the last few decades, technology has become a necessary tool used in nearly every single domain known to mankind. Before the 21st century, however, there were many advances made in the field of 3D printing. Printed circuit boards were used to fabricate the first-ever cell phone, but today, its tasks are much more complicated than that. With circuit boards came the invention of 3D printers, which are now a needed asset in development and medical fields. The following are 4 different types of 3D printers and what they’re used for.


Stereolithography is one of the oldest methods of 3D printing, but it is still very much used today. This type of 3D printer is often used to print objects of the 3D variety. The stereolithography is very useful and often used by engineers or hobbyists who need to verify that their desired parts are going to fit their prototypes. First invented in 1986, the stereolithography has long since evolved into a modern day technology, and is commonly used with a computer aid software.

Digital Light Processing

Digital light processing and stereolithography have a lot of attributes in common, however, they deliver a different outcome. To get its final result, DLP puts digital micro mirrors to work by laying them out on a semiconductor chip, which is also the way that cell phones and projectors are made. One of the main differences between stereolithography and digital light processing is that they use a different light source. Digital light processing is often paired up with more renown light sources like lamps or light bulbs. To print with the DLP, one needs to procure themselves with liquid plastic resin, and place it inside of the resin container.

Fused Deposition Modeling

Fused Deposition Modeling is a technology that has been around since the 1980’s. Since then, its creator Scott Crump, has perfected the 3D printer and sold its making to check here other 3D printing companies, however, these companies have changed the 3D printer’s name. Fused deposition modeling is more commonly used to print out prototypes for complex technologies. These parts are printed out in top-quality thermoplastics, making anything printed out by this technology intricately made.

Selective Laser Sintering

Selective laser sintering is a 3D printer unlike any other. This is because it uses lasers to create 3D objects. First invented by Carl Deckard and Joe Beaman in the 1980’s, the selective laser sintering method was then sold and adopted by 3D Systems in the early 21st century. Selective laser sintering is often compared to the stereolithography 3D printer, but their biggest difference is that selective laser sintering uses liquid resin materials while the stereolithography 3D printer uses powdered materials.
