What is 3D printing? This article goes over the basics of 3D printing, otherwise known as additive manufacturing, covering its engineering principles and applications.

What is 3D printing? Also known as additive manufacturing, 3D printing is a transformative technology that enables the creation of complex, three-dimensional objects by depositing material layer by layer. This technology has revolutionized various industries, from aerospace and automotive to healthcare and consumer products, by offering unprecedented design flexibility, reduced lead times, and cost savings.

This guide attempts to answer the common question, “What is 3D printing?” by focusing on the engineering principles and applications of 3D printing, providing a comprehensive understanding of the fundamental concepts, materials, hardware components, software tools, and real-world applications of the technology.

3D Printing Technologies

3D printing, or additive manufacturing, is a process that creates three-dimensional objects layer by layer, following a digital model or blueprint. This technology has gained significant attention in recent years due to its ability to produce complex geometries, reduce material waste, and shorten production times compared to traditional manufacturing methods.

There are several types of 3D printing technologies, each with its own set of advantages and limitations, depending on the specific application and material requirements.

Fused Deposition Modeling (FDM)

FDMFDM dominates the consumer 3D printing market

Fused deposition modeling (FDM) or fused filament fabrication (FFF) is one of the most widely used 3D printing technologies, known for its simplicity, affordability, and versatility. FDM works by extruding a thermoplastic filament through a heated nozzle, which deposits the material onto a build platform in a layer-by-layer fashion, following a predetermined path defined by the digital model.

FDM offers several advantages, such as the ability to print with a wide range of thermoplastic materials, including PLA, ABS, and PETG, which have different mechanical and thermal properties suitable for various applications. FDM printers are also relatively affordable and easy to use, making them popular among hobbyists, educators, and small businesses.

However, FDM has some limitations, such as lower resolution and surface finish compared to other 3D printing technologies, as well as the need for support structures when printing overhangs and complex geometries. Parts are also anisotropic; they are weaker along one axis due to weaker bonds between layers.[1] Despite these limitations, FDM remains a popular choice for many 3D printing applications, such as rapid prototyping, functional testing, and low-volume production of plastic parts.

Stereolithography (SLA)

Stereolithography (SLA) is another widely used 3D printing technology that creates objects by selectively curing a liquid photopolymer resin using ultraviolet (UV) light. SLA offers higher resolution and surface finish compared to FDM, making it suitable for applications that require intricate details and smooth surfaces.

The SLA process involves the use of a UV laser that traces the cross-sectional pattern of the object onto the surface of the liquid resin, causing it to solidify and adhere to the build platform or the previous layer. The build platform is then incrementally lowered, allowing the next layer of resin to be exposed and cured. This process is repeated until the entire object is built.

SLA offers several advantages over FDM, such as higher resolution, smoother surface finish, and the ability to produce more intricate and complex geometries. However, SLA also has some limitations, such as the need for support structures to prevent deformation and the relatively limited range of available materials, which are primarily limited to photopolymer resins. These resins can be brittle and may degrade over time when exposed to UV light, making them less suitable for certain applications.

Despite these limitations, SLA is a popular choice for applications that require high-resolution and detailed parts, such as jewelry, dental models, and prototypes for injection molding. By understanding the principles and capabilities of SLA, engineers can leverage this technology to create high-quality, intricate objects that are difficult or impossible to produce using other 3D printing methods.

Selective Laser Sintering (SLS)

Selective Laser Sintering (SLS) is a 3D printing technology that uses a high-power laser to fuse powdered material, such as nylon, polyamide, or metal, into solid objects layer by layer. SLS is known for its ability to produce durable and functional parts with complex geometries and good mechanical properties, making it suitable for a wide range of applications, from prototyping to end-use products. Most SLS systems are targeted at professional or industrial users rather than hobbyists or small businesses.

In the SLS process, a thin layer of powdered material is spread across the build platform, and a laser scans the surface, following a predetermined pattern that corresponds to a cross-section of the object being printed. The laser heats the powder to a temperature just below its melting point, causing the particles to fuse together and form a solid layer. Once a layer is completed, the build platform is lowered, and a new layer of powder is spread on top. This process is repeated until the entire object is printed.

One of the key advantages of SLS is its ability to produce parts with complex geometries and internal structures, such as lattice structures and hollow cavities, without the need for support structures.[2] This is because the unfused powder surrounding the printed part acts as a natural support, preventing deformation and allowing for the creation of intricate designs. SLS also offers good mechanical properties.

However, SLS also has some limitations, such as the need for post-processing to remove excess powder and improve surface finish, as well as the relatively high cost of the equipment and materials compared to other 3D printing technologies like FDM and SLA.

Direct Metal Laser Sintering (DMLS)

DMLSDMLS can produce production-quality metal parts

Direct metal laser sintering (DMLS) or powder bed fusion (PBF) — sometimes referred to by the proprietary term Selective Laser Melting (SLM) — is an advanced, industrial-grade 3D printing technology specifically designed for printing metal parts. The process involves using a high-power laser to selectively fuse metal powders, layer by layer, into fully dense and functional metal components. DMLS offers exceptional precision and allows for the creation of complex geometries that would be challenging or impossible to achieve using traditional manufacturing methods.

The versatility of DMLS allows for the use of various metal materials, such as stainless steel, aluminum, titanium, and even high-performance alloys, making it well-suited for applications in aerospace, automotive, medical, and other industries that demand durable and high-quality metal parts. It is capable of producing production-quality metal parts as well as prototypes.

One of the advantages of DMLS is its ability to produce parts with excellent mechanical properties, approaching or even exceeding the strength of conventionally manufactured components. However, the process can lead to residual stresses and warping, necessitating careful design considerations and post-processing steps to achieve the desired properties and dimensional accuracy. DMLS machines and materials require careful handling and should only be used in an industrial environment.

Electron Beam Melting (EBM)

Electron beam melting (EBM) is an additive manufacturing technology that utilizes an electron beam to selectively melt and fuse metal powders into complex and fully dense 3D parts. EBM is particularly well-suited for printing high-performance metal components with excellent mechanical properties.

During the EBM process, a focused electron beam scans the surface of a powdered metal bed, melting the material in specific regions based on the digital model's cross-section. As each layer is completed, the build platform is incrementally lowered, and a new layer of powder is spread on top. This layer-by-layer approach enables the creation of intricate geometries and internal structures without the need for support structures.

EBM offers distinct advantages, including its ability to produce parts with superior material properties, especially in terms of mechanical strength and fatigue resistance. This makes EBM a preferred choice for critical applications in aerospace, medical implants, and the automotive industry.

However, EBM has certain limitations, such as slower build times compared to some other metal 3D printing methods like DMLS. Additionally, the high vacuum environment required for the process and the specialized equipment can contribute to higher capital costs.[3] Despite these factors, EBM remains a powerful technology for fabricating high-quality metal components that meet the stringent requirements of demanding industries.

Directed Energy Deposition (DED)

Directed energy deposition (DED) is an additive manufacturing technique that involves the precise deposition of material, typically metal powders or wires, onto a substrate using a high-energy heat source, such as a laser or an electron beam. DED is known for its versatility, as it allows for the repair, modification, or building up of existing parts, making it valuable for industries that deal with large-scale components and expensive materials.

During DED, the heat source melts the material as it is being deposited, resulting in excellent metallurgical bonding with the substrate or previous layers. This process enables the creation of near-net-shape parts, reducing material waste and minimizing post-processing requirements.

DED finds applications in various industries, including aerospace, oil and gas, and automotive, where it is used for repairing worn-out components, adding features to existing parts, or building custom-designed structures with a wide range of materials. However, the process can introduce thermal stresses and distortion, necessitating careful process control and stress relief techniques.

Binder Jetting

Binder jetting is an additive manufacturing process that utilizes a liquid binding agent to selectively fuse powdered materials, such as sand, metal, or ceramics, into solid objects. The process begins with the spreading of a thin layer of powder on the build platform. A print head then deposits the liquid binder onto the powder in a pattern defined by the digital model's cross-section.

One of the key advantages of binder jetting is its ability to print large and complex parts quickly, making it suitable for applications in architecture, aerospace, and automotive industries. Additionally, the technology allows for the production of sand molds and cores for metal casting processes without the need for a pattern, greatly reducing lead times.[4]

However, binder jetting typically produces parts with lower mechanical properties compared to technologies like DMLS or SLS. Post-processing steps, such as sintering to improve material strength and surface finish, are often necessary. Despite these considerations, binder jetting remains an attractive choice for rapid and cost-effective prototyping and production of parts in a variety of materials.
