While custom manufacturing may have a higher upfront cost per unit compared to mass production, it can be more cost-effective in specific scenarios, especially when factoring in the reduced need for inventory and waste, as well as the ability to make small production runs without investing in expensive tooling. Custom manufacturing also reduces the risk of producing large quantities of parts that may not meet specifications, saving money on revisions and adjustments. For companies with precise or low-volume needs, custom manufacturing offers a better return on investment by providing exactly what is needed without excess production or material waste.
Custom manufacturing encompasses a wide variety of processes, each designed to meet specific project requirements. Depending on the part design, material selection, and intended application, different manufacturing techniques can be utilized to achieve optimal results. The two primary categories of custom manufacturing processes are additive manufacturing and subtractive manufacturing. Below, we explore the technologies associated with each.
Additive Manufacturing
Additive manufacturing involves creating objects by adding material layer by layer, typically using 3D printing technologies. This process is highly flexible and enables the production of complex geometries that would be difficult or impossible to achieve using traditional manufacturing techniques. Additive manufacturing is ideal for rapid prototyping and small-scale production of custom parts.
These additive manufacturing technologies include:
Stereolithography (SLA): SLA uses a laser to cure liquid resin into solid parts layer by layer. It is highly accurate and provides smooth surface finishes, making it ideal for prototypes and small, detailed parts.
Selective Laser Sintering (SLS): SLS uses a laser to sinter powdered material into a solid structure. It works with a variety of materials, including metals and polymers, making it versatile for custom manufacturing.
Fused Deposition Modeling (FDM): FDM extrudes thermoplastic material layer by layer to create parts. It’s a cost-effective method for creating durable, functional prototypes and end-use parts.
Poly Jetting: This process sprays layers of photopolymer onto a build platform and cures them with UV light. It allows for multi-material printing and high-resolution parts.
Binder Jetting: In binder jetting, a liquid binder is used to adhere powder particles, layer by layer. It is often used for metal and ceramic parts and can produce larger, more complex shapes.
Fused Filament Fabrication (FFF): FFF is similar to FDM and involves depositing melted material layer by layer to create a part. It is widely used for making functional prototypes and small production runs.
Selective Laser Melting (SLM): SLM melts and fuses metal powders into solid parts using a high-energy laser. It’s commonly used for creating high-strength metal parts in industries such as aerospace and medical devices.
Multi Jet Fusion (MJF): MJF uses a combination of fusing and detailing agents applied to a bed of powder, followed by heat to create precise, functional parts.
Direct Metal Laser Sintering (DMLS): DMLS is similar to SLM but uses sintering instead of full melting. It’s effective for creating strong, dense metal parts directly from digital models.
Electron Beam Melting (EBM): EBM uses an electron beam to melt metal powder, layer by layer. It is known for producing parts with excellent material properties, making it popular in aerospace and medical applications.
Subtractive Manufacturing
Subtractive manufacturing involves removing material from a solid block (workpiece) to create the desired shape. This process is the foundation of CNC machining and other traditional manufacturing methods. Subtractive manufacturing is ideal for parts that require high precision, tight tolerances, and superior surface finishes.
Typical subtractive manufacturing technologies include:
