FDM 3D printing produces custom mahjong tiles in full color straight off the printer — no molds, no painting, no minimum order limits. This guide covers materials, costs, turnaround times, and use cases to help buyers make informed sourcing decisions.

What is the actual difference between a 2 plate mold and a 3 plate mold in plastic injection molding? While product engineers and buyers often confuse the two, understanding their parting lines, gate positions, and production modes is critical. Read our selection guide to find the perfect match for your design.

Discover 7 practical ways to reduce prototype costs through smarter design, material selection, optimized tolerances, and the right manufacturing process such as CNC machining, 3D printing, or vacuum casting.

This guide compares CNC machining and injection molding in terms of cost, speed, precision, materials, and production volume. Learn when to use CNC for prototyping and low-volume parts, and when injection molding becomes the better choice for mass production.

This article compares sheet metal and 3D printing for functional rapid prototyping, highlighting differences in cost, lead time, material performance and DFM validation. It explains the pros, cons and suitable materials of both processes for structural and thermal testing. It recommends a practical hybrid strategy: use 3D printing for early design fit checks, then sheet metal for real functional verification and production-ready validation to reduce cost and manufacturing ris

Custom brass CNC machining offers high precision, excellent machinability, and fast turnaround for industries like automotive and electronics. SG PROTO delivers tight tolerances up to ±0.01mm, multi-axis machining, and complete finishing solutions for prototypes and small-batch production.

Nylon 3D printed parts often have a rough, porous surface, especially with SLS and MJF technologies. This article explains how vapor smoothing improves surface finish, enhances mechanical properties, and delivers professional-quality results. Discover why vapor polishing is the ideal post-processing solution for functional prototypes and end-use nylon parts.

From design to delivery, SG PROTO offers a fully controlled prototyping workflow. Our process includes material sourcing, engineering review, precision machining (CNC, 3D printing, vacuum casting), surface finishing, and final inspection—ensuring every part meets exact specifications in both function and appearance.
