Introduction: When Standard Resins Fail Under Heat Hi, I’m Barry Zeng, a manufacturing engineer at Shanghai Yunyan Prototype & Mould Manufacture Factory. Over the years, I’ve seen many SLA Resins 3D Printing projects fail because the parts couldn’t withstand heat.…
Introduction: The Journey from Hazy to Crystal Clear Hi, I’m Barry Zeng, a manufacturing engineer at Shanghai Yunyan Prototype & Mould Manufacture Factory. One of the most satisfying transformations I see in our shop is taking a hazy, translucent Clear…
Introduction: The Resin Makes the Part Hi, I’m Barry Zeng, a manufacturing engineer at Shanghai Yunyan Prototype & Mould Manufacture Factory. Over the years, I’ve printed thousands of parts using SLA 3D Printing — from detailed jewelry patterns to functional…
Introduction: Why Most Quote Requests Get Delayed — And How to Avoid That Hi, I’m Barry Zeng from Shanghai Yunyan Prototype & Mould Manufacture Factory, a manufacturing factory specializing in CNC machining, 3D printing (SLA/SLS/FDM), and sheet metal fabrication. Every…
Introduction: Choosing the Right 3D Printing Technology 3D printing has revolutionized prototyping and low‑volume production, but not all 3D printing technologies are created equal. Stereolithography (SLA), Selective Laser Sintering (SLS), and Fused Deposition Modeling (FDM) are three of the most…
Introduction: The Backbone of Modern Custom Manufacturing In an era where 3D printing and other additive technologies capture headlines, CNC machining manufacturing remains the undisputed backbone of precision custom manufacturing. From aerospace components that must withstand extreme conditions to medical…
Introduction: The Critical Leap from “Raw” to “Finished” When a 3D printed metal part is removed from the powder bed, it is far from ready for delivery. Unmelted powder adhering to the surface, support structure remnants, internal residual stresses, and…
Introduction: Lightweighting – An Eternal Mission for the Automotive Industry Automotive lightweighting is not an option – it is a necessity. According to the International Aluminum Institute, a 10% reduction in vehicle weight can improve fuel efficiency by 6-8% and…
Introduction: A Classic Car’s “Resurrection” and the Transformation of the Spare Parts Supply Chain Last autumn, our received a special call for help. A classic car collector owned a 1972 Ferrari 365 GTB/4 Daytona. A plastic fuel distributor on the…
Introduction: Two Mainstream Technologies, Two Different Cost Logics In the world of 3D printing, SLA (Stereolithography) and SLS (Selective Laser Sintering) are the two most widely used industrial technologies. SLA excels at high‑precision, smooth‑surface appearance parts; SLS requires no supports…
