Professor Fu from Wuhan University of Engineering used Xometry's 3D printing services to manufacture large-size custom components for robot assembly. Xometry's global manufacturing network enabled integrated one-piece forming of oversized parts, overcoming challenges of deformation, interlayer bonding, and temperature fluctuation during printing. The solution included support for surface finishing and fast lead time.

Custom 3D Printed Large-Size Components for Robotics
Xometry’s high-quality and fast delivery exceeded our original expectations. We inspected the components right after unboxing and were genuinely impressed. This was our first time using an on-demand manufacturing platform for custom production. The whole process was smooth with timely response. They solved our problems efficiently and removed all worries for our subsequent custom design work.
Professor Fu from Wuhan University of Engineering shared his experience using Zemi Technology on how large-size components for assembling robots can be produced with the desired high quality on schedule, and whether they can be delivered smoothly as needed.
01 Manufacturing Difficulties of Large-Size Parts: High-quality and Stable Structure
In 3D printing of large-size components, integrated one-piece forming and maintaining structural stability without deformation remain core challenges. Multiple manufacturing risks constantly restrict smooth production.
First, limited by the build volume of 3D printers, oversized parts often require segmented printing, which increases the difficulty of subsequent assembly and splicing. One-piece integrated forming is technically demanding and requires strong manufacturing capability.
In terms of material performance, interlayer bonding is another major challenge. Bonding strength between printing layers tends to be insufficient, and the problem becomes more prominent in large-scale 3D printing.
In addition, large components are prone to deformation and warpage caused by temperature fluctuation and material shrinkage during printing. Post-processing also poses difficulties; surface finishing such as grinding and polishing is more complex for oversized parts and may compromise final quality.
Therefore, manufacturing large-size components highly tests a supplier’s technical capability, and directly determines rework frequency and overall project progress. It is critical to ensure structural stability of large parts while supporting follow-up surface spraying, and finally deliver finished products with high quality.
Large-Size Custom Robot Component Designed by the Client
02 Special Manufacturing Requirement: Fast Lead Time
The client had strict requirements on delivery schedule, making fast production of large-size components particularly challenging. Coordinating the most suitable manufacturer becomes the top priority.
Unlike mass-produced products, customized parts require full-process collaboration. Supporting one-piece production and fast response to custom demands are major challenges beyond design itself.
With a global network of over 10,000 manufacturers, Xometry can rapidly respond to diverse lead time requirements and allocate multi-resource arrangements. It supports more than 15 manufacturing processes and a wide range of special materials, delivering on-demand manufacturing solutions for complex production challenges.
Professor Fu from Wuhan Institute of Engineering commented:
“Xometry’s high-quality and fast delivery exceeded our expectations. We inspected the components immediately after unboxing and were very impressed with the quality. This was our first experience using an on-demand manufacturing platform for custom production. The overall experience was seamless with timely response. They solved our technical challenges in a short time and gave us full confidence for future custom design projects.”
