Important 3D Printing Terms Explained in Simplified Language

3D printing has come a long way in the past decade. And while the technology is still in its infancy, it’s increasingly becoming a part of our everyday lives. We use it to create personalized gifts and decorations, and even to print prosthetic limbs. However, for those who are unfamiliar with the term, 3D printing can often seem like a complicated topic.

That’s why we’ve put together a list of the most important 3D printing terms. From additive to subtractive, this list covers it all. So, if you want to get started with 3D printing but don’t know where to begin, keep reading.

What is 3D Printing?

3D printing is the process of making three-dimensional (3D) products by printing materials layer by layer using a 3D printer. It’s often referred to as additive manufacturing, because the printing process is based on the same principle as adding color to a two-dimensional drawing. But while traditional printing applies ink or other medium to a flat surface, 3D printing adds shape and structure to solid materials.

FDM (Fused Deposition Modeling)

FDM is the most common form of 3D printing. It works with a variety of materials, including plastics, metals, ceramics, and composites. The machine uses a laser to heat the individual filaments in a cloth or mist of material, causing them to fuse together. This is known as sintering, and it creates a solid structure with no waste. The FDM process is available in two forms: subtractive and additive.

SLS (Selective Laser Sintering)

SLS printing uses a similar technology to SLA, but it works with composites instead of polymers. Like SLA, SLS works through selective deposition, which fuses different materials together. The primary difference between the two is that SLS prints use a laser to fuse different materials at different temperatures. This allows SLS printers to combine different materials to create complex structures. SLS printing can also be used to create parts with fine details, such as tiny gears or pins.

FFF (Fused Filament Fabrication)

FFF printing works differently from the other types of 3D printing. The printer melts or fuses different types of filament together to create a solid object. FFF printers can print with a wide range of materials, including polymers, composites, andsolids. The printing process itself is similar to SLS printing, but the equipment is different.

BIM (Building Information Modeling)

BIM is the process of modelling a building or other structure using 3D modeling software. This can be for design review, construction documentation, or training purposes. The model can be static or animated. BIM is often used in architecture, construction, and engineering. However, it can also be valuable for managing the manufacturing of 3D printed products, as it can help to track part or all of a product’s lifecycle.

RAPID (Rapid Application of Digital Technology)

RAPID is another term that is often confused with 3D printing. RAPID is a method of manufacturing that uses additive technologies, such as 3D printing, to produce rapid prototypes or limited runs of products. It’s often used to test new products or manufacturing techniques in advance, before exploring larger scale production techniques.

ASA (Applied Sciences and Automation)

ASA is making a comeback. The organization was originally formed to ensure the safety of 3D printing, but it has recently expanded its mission to include the application of 3D printing in the service of science and technology. As the name suggests, the primary focus is on the applied sciences, such as mechanical engineering, electrical engineering, and materials science.

Conclusion

As 3D printing becomes more accessible, its uses are expanding beyond prototyping. This technology is now even able to fabricate living tissues, such as bone and cartilage.
