About us

At Shenzhen Pans Technologies, we offer 3D printing for short-run productions. We use silicone tooling and urethane and silicone casting to provide a cost-effective service with quick turnaround. Our short-run manufacturing is a flexible, quick, and cost-effective process for a stop-gap solution and even final production needs. Materials we work with include silicones, urethanes, epoxy, rubber, polypropylene, transparent, Nexa3D and SL resins. Our equipment supports build envelopes up to 600 x 600 x 450 mm in size but we are able to bond several parts together for larger pieces. Tolerance for SL parts is ± 0.005 in. + 0.001 in./in. and for cast urethanes is ± 0.010 in. + 0.002 in./in. We also provide additional services such as finishing, painting, custom pigmenting, assembly, fabrication, testing, product design and development.

Why choose 3D printing?

Table 1: Advantages of 3D Printing Compared to CNC Machining

Aspect	Advantage
Design Freedom	Allows for complex geometries, internal structures, and organic shapes impossible with CNC.
Material Utilization	Minimal material waste, as only the required material is used during the process.
Setup Time	Minimal setup time; no need for tooling or fixtures.
Customization	Easily customizable; ideal for prototyping or small-scale production with design iterations.
Complexity vs. Cost	Complexity adds little to cost, enabling intricate and customized designs without extra expense.
Sustainability	More environmentally friendly due to reduced material waste and potential use of recyclable materials.
Automation	Highly automated, requiring minimal human intervention once the process is set up.

Why still need CNC machining?

Table 2: Limitations of 3D Printing Compared to CNC Machining

Aspect	Limitation
Precision and Tolerance	Generally lower precision compared to CNC, with tolerances typically in the range of ±0.1–0.2mm.
Surface Finish	Often requires post-processing for smooth finishes, especially in FDM and powder-based methods.
Material Strength	Some 3D-printed materials are less durable or strong compared to CNC-machined materials.
Scalability	Not ideal for high-volume production due to slower build times and higher costs for large-scale manufacturing.
Production Speed	Slower for mass production compared to CNC, which is optimized for efficiency in high volumes.
Material Variety	Limited material performance; some engineering materials (e.g., hardened steel) are not widely available for 3D printing.
Cost Efficiency	Less cost-effective for large-scale production compared to CNC machining.
Post-Processing	Requires additional steps such as support removal, curing, or surface treatment.
