3D printing is an exciting yet complex field, and as a beginner, it can be overwhelming to dive into the world of 3D printing terminology. With so many different materials, technologies, and processes to understand, it's easy to get lost in the jargon. You may have even found yourself wondering, "Is SLS the same as SLA?" or "What's the difference between PA and PLA?"
Don’t worry — we’re here to help! In this blog, we’ve compiled a helpful 3D printing glossary that explains the most common acronyms and terms you'll encounter. Whether you're just getting started or looking to deepen your knowledge, this dictionary will make it easier to navigate the 3D printing world and start creating your own designs with confidence.
Additive Manufacturing, often used interchangeably with 3D printing, refers to the process of creating objects by adding material layer by layer. This is in contrast to subtractive manufacturing, where material is removed to form a shape. Additive technologies include methods like FDM, SLA, SLS, and others that use different materials and processes to create 3D-printed models.
ABS is a common thermoplastic polymer used in FDM 3D printing. It is a strong, durable plastic that melts when heated, making it easy to extrude into 3D printed shapes. ABS is known for its toughness and ability to be molded, making it a popular choice for functional parts and prototypes.
CAD refers to the software used to create 3D models for printing. These programs allow designers and engineers to design, modify, and analyze objects in a digital space before they are printed. Popular CAD programs for 3D printing include AutoCAD, Fusion 360, and SolidWorks.
DMLS is a technique for 3D printing metals using a high-powered laser to sinter (melt) metal powder into solid parts. This process is typically used for manufacturing functional metal parts in industries such as aerospace, automotive, and medical. Materials like aluminum and titanium are commonly used in DMLS printing.
FDM is one of the most popular 3D printing technologies for beginners. It works by heating thermoplastic filaments, like ABS or PLA, and extruding them through a nozzle to build objects layer by layer. FDM is commonly used in home 3D printers due to its accessibility, affordability, and ease of use.
FFF is essentially another name for FDM (Fused Deposition Modeling). The term was created to avoid the legal restrictions surrounding the FDM trademark. Like FDM, FFF involves the extrusion of thermoplastic filament to create 3D models, and the two terms are used interchangeably in many contexts.
HP's Multi Jet Fusion (MJF) technology is a powder-based 3D printing process similar to SLS (Selective Laser Sintering). Instead of using lasers, MJF uses a fusing agent that is jetted onto the powdered material to bond it together. The result is a strong and flexible material with detailed surfaces and thinner walls. MJF is ideal for creating durable, functional parts.
Polyamide, also known as nylon, is a thermoplastic material used in SLS 3D printing. It is available in powder form and is popular for its durability, flexibility, and strength. Polyamide prints have a slightly granular texture, but the material offers excellent freedom for intricate designs, making it a favorite among designers for functional parts and prototypes.
PLA is a biodegradable thermoplastic made from renewable resources like corn starch or sugarcane. It is commonly used in FDM 3D printing and is well-known for being easy to print with, making it popular among hobbyists and beginners. PLA is less durable than ABS and is more brittle but is ideal for decorative items and non-functional prototypes.
Stereolithography (SLA) is a resin-based 3D printing process that uses a UV laser to cure liquid resin layer by layer to form solid objects. It is known for producing highly detailed models with smooth surfaces, making it a popular choice for jewelry designers, dental applications, and high-precision prototypes. SLA printers can create intricate details with a high degree of accuracy.
Selective Laser Sintering (SLS) is a powder-based 3D printing technology that uses a laser to sinter (melt) a fine powder material, typically plastic or metal, into solid parts. This technology does not require support structures because the unused powder supports the model during printing. SLS is ideal for producing complex, functional parts and is widely used in aerospace, automotive, and medical industries.
STL is the most common file format used for 3D printing. Files in the STL format represent the surface geometry of a 3D model and are used by 3D printers to build objects layer by layer. While STL is often thought to stand for STereoLithography, some believe it could also stand for "Standard Triangle Language" or "Standard Tessellation Language." It's a widely supported format and works with almost all 3D design and printing software.
TPU is a flexible, rubber-like material used in 3D printing to create objects with elasticity. It is known for its durability and high resistance to abrasion and wear, making it ideal for parts that need to be bendable, stretchable, or shock-absorbing. TPU 92A-1 is a common variety used in 3D printing for items like phone cases, wearables, and soft, flexible components.
As you begin your journey into the world of 3D printing, you'll encounter a lot of new terms and acronyms. Understanding the terminology is the first step toward mastering the technology and creating amazing 3D-printed models. Whether you’re using FDM, SLA, or SLS, or printing with materials like PLA, ABS, or TPU, knowing these basic terms will help you make informed decisions as you progress in your 3D printing journey.
3D printing is like a marathon, not a sprint, so take your time to learn and experiment. The more you know, the more confident you’ll become in your ability to create custom designs.
