Production 3D printing, also known as additive manufacturing, is a cutting-edge technology that enables businesses to create complex parts and products in a highly efficient and cost-effective manner. It involves the layer-by-layer fabrication of three-dimensional objects based on digital designs. This approach not only reduces material waste but also allows for the creation of intricate geometries that were once challenging or even impossible to achieve using traditional methods. Production 3D printing also enables on-demand manufacturing, eliminating the need for large-scale, fixed production lines. With this technology, companies can produce parts and products as needed. On-demand manufacturing also opens up new opportunities for customized and personalized products, as each item can be tailored to meet individual customer requirements.
Xometry’s production 3D printing process is a comprehensive set of workflow steps that involves several key stages. The process begins with part design, during which digital 3D models of a desired product are created using computer-aided design (CAD) software. Next, the properties of candidate materials that could be used to 3D print the product are carefully evaluated to ensure that they match up with the intended application and its requirements.
Likewise, the chosen material and the design of the part will feed into the decision about which 3D printing technology makes the most sense for the application. The selected method might be fused deposition modeling (FDM), stereolithography (SLA), or selective laser sintering (SLS), to name a few of the more common techniques.
Once the design, the material, and the printing method are chosen, the 3D model is prepared for printing using software that "slices" the 3D model into layers that can be printed, converting the information into instructions that can be understood by the printer. The printer then follows the provided instructions and deposits the chosen material layer by layer, gradually constructing the final part.
Post-processing is often required to refine the printed parts and achieve the desired surface finish and mechanical properties. Throughout the production 3D printing process, quality assurance is paramount. Various inspection methods, such as visual inspection, dimensional measurement, and non-destructive testing, are employed to ensure that the printed parts meet the required specifications and standards.

Advantages of Production 3D Printing
Production 3D printing offers numerous advantages that set it apart from traditional manufacturing processes, including:
- Reduced Waste
- Design Iterations
- Cost Effective
- On-Demand Production
- Reduced Lead Times
- Lightweight Materials
Additive manufacturing builds parts layer by layer, using only the necessary amount of material. This not only reduces material costs but also contributes to more sustainable and environmentally friendly production practices.
Production 3D printing allows for unparalleled design freedom, enabling the creation of intricate geometries and complex structures that would be challenging or impossible to achieve through traditional methods. This design flexibility empowers engineers and designers to iterate quickly on their designs, testing and refining concepts with ease.
For complex parts with intricate designs, production 3D printing can offer cost savings compared to traditional manufacturing processes. 3D printing eliminates the need for tooling, making it cost-effective for producing small batches or one-off parts without sacrificing quality. This advantage is also associated with the "complexity paradox," a concept wherein the complexity of a part doesn't necessarily increase its cost when using 3D printing. Additionally, 3D printing's "Just in Time" production approach can mitigate storage costs and reduce risks for companies, making it a viable alternative for low-volume manufacturing scenarios.
The lead time for producing a 3D-printed part, from concept to finished product, is shorter than for other fabrication processes. This is because design files can be quickly sent to the printer, and parts can be fabricated without the need for lengthy setup times or complex assembly processes. This rapid turnaround time makes 3D printing ideal for time-sensitive projects and on-demand production requirements.
Production 3D printing enables on-demand manufacturing, meaning that parts can be printed as needed rather than being produced in large quantities and stored in inventory. This on-demand approach reduces storage costs and the risk of overstocking.
With streamlined workflows and minimized setup requirements, Xometry’s production 3D printing services can significantly reduce lead times from design concept to final product. Complex parts that once took weeks or months to produce using traditional methods can now be manufactured within days.
Production 3D printing facilitates product customization on a scale that was previously impractical with traditional manufacturing processes. Businesses can easily tailor products to meet individual customer preferences, even at low volumes.
For industries where lightweight materials are essential, such as aerospace and automotive, production 3D printing offers a distinct advantage. Additive manufacturing allows for the use of advanced lightweight materials and optimized designs. Materials like titanium aluminide (TiAl), known for its high-temperature strength, and carbon fiber reinforced polymers (CFRP), combining strength and low weight, are prime examples. 3D printing enables intricate designs and precise placement of materials, enhancing properties like strength-to-weight ratios. Even commonplace materials like aluminum can be optimized for lightweight structures through additive manufacturing, showcasing the technology's versatile application. Additionally, 3D printing excels in crafting intricate cellular structures that offer exceptional strength with minimal weight, a feat difficult to achieve through conventional manufacturing methods.
