3D Printing

Introduction Manufacturing has always been about transformation—turning raw materials into useful objects. For centuries, that meant cutting away what wasn't needed (subtractive) or forcing material into molds (formative). Additive manufacturing—building objects layer by layer from digital files—offers a fundamentally different approach. This shift brings advantages that traditional methods cannot match: design freedom that makes complexity […]

Introduction ABS (Acrylonitrile Butadiene Styrene) is everywhere. It's the plastic in LEGO bricks, car dashboards, power tool housings, and drone frames. It's strong, tough, and heat-resistant. But anyone who's tried 3D printing ABS knows the struggle: These issues aren't just annoying. They make ABS feel more trouble than it's worth. The truth? ABS has unique

Introduction For decades, making injection molds meant one thing: CNC machining. Cut away metal from a solid block until the desired shape emerges. It works. It's precise. But it has limits—long lead times, geometric constraints, and cooling channels that can only be drilled in straight lines. 3D printed molds change everything. By building molds layer

Introduction Fasteners are the unsung heroes of manufacturing. Screws, bolts, nuts, washers, rivets—they hold our world together. Every product, every machine, every structure depends on them. But what if you could design your own fasteners? Custom threads, unique head shapes, integrated features—all printed exactly when you need them? That's the promise of 3D printed fasteners.

Introduction Imagine a 3D printer that works like an inkjet printer—but instead of depositing ink on paper, it deposits liquid plastic, wax, or even metal, building objects layer by layer with incredible detail and precision. That is jetting 3D printing. This family of technologies combines the speed of inkjet printing with the design freedom of

Introduction 3D printing—also called additive manufacturing—has moved far beyond its early days as a prototyping novelty. It's now a transformative force reshaping how products are designed, manufactured, and delivered. Unlike traditional methods that cut away material, additive manufacturing builds objects layer by layer from digital files. This fundamental difference unlocks possibilities that were previously impossible:

Introduction In every factory, assembly line, and machine shop, there are unsung heroes: jigs and fixtures. These simple tools hold parts in place, guide cutting tools, and ensure every operation is accurate and repeatable. They are essential—but traditionally, they are also expensive and slow to produce. A custom fixture might take weeks to machine and

Introduction 3D printing has transformed from a niche prototyping tool into a mainstream manufacturing technology. Yet many professionals still struggle with basic questions: These aren't trivial questions. The wrong choice can mean failed prints, wasted material, and missed deadlines. At Yigu technology, we've helped hundreds of clients navigate these decisions. This guide breaks down 3D

Introduction You have a great idea for a 3D printed project. You've designed the model. You're ready to print. But then comes the question: how much will it cost? The answer isn't simple. Plastic 3D printing costs vary wildly based on material, printer type, part size, complexity, and dozens of other factors. A small keychain

Introduction 3D printing materials are the unsung heroes of the manufacturing revolution. While printers get the attention, it's the materials that enable new possibilities—stronger parts, lighter components, complex geometries, and customized solutions. Consider a critical engine component for a high-performance vehicle. Traditionally, producing it took months—multiple molds, extensive machining, significant waste. With 3D printing materials,

Introduction For decades, manufacturing meant either cutting away material from solid blocks or forcing it into molds. Both work, but both have limits—waste, complexity constraints, long lead times. Solid-Based Additive Manufacturing (SBAM) offers a third path. By building parts layer by layer from digital files, it creates geometries impossible with traditional methods, reduces waste dramatically,

Introduction Resin 3D printing has evolved far beyond its hobbyist roots. What once produced fragile, low-quality models now creates engineering-grade parts with precision that rivals injection molding. For engineers and product designers, the goal has shifted from "can I print this?" to "can I print this to meet strict performance standards?" The answer, with the

Introduction Imagine you need to create a highly detailed prototype—a piece of jewelry with intricate patterns, a dental model with precise anatomy, or a concept car part for aerodynamic testing. Traditional methods would take weeks and cost thousands. SLA 3D printing delivers these parts in hours or days, with smooth surfaces and details that other

Introduction 3D printing has come a long way since its early days. What started as a slow, expensive technology with limited materials has evolved into a manufacturing powerhouse capable of producing end-use parts at scale. Today's leading 3D printing companies are not just selling printers. They're offering complete manufacturing solutions—from design to production to post-processing.

Introduction Fan blades are everywhere. In your computer, keeping it cool. In industrial ventilation systems, moving air through factories. In aircraft engines, pushing planes through the sky. They seem simple—just spinning blades moving air. But their design profoundly affects efficiency, noise, and performance. Traditional manufacturing limits what's possible. Casting, forging, and machining restrict shapes to

Introduction You've just finished a beautiful resin print—a detailed figurine, a precise dental model, or a functional prototype. It looks perfect on the build plate. But if you handle it, it feels slightly soft or tacky. A few days later, it develops small cracks or warps out of shape. What went wrong? You skipped or

Introduction Your business has a great idea. You need prototypes, custom parts, or small production runs. Buying a 3D printer seems like the obvious move—until you realize the costs: equipment, maintenance, materials, training, and the time to learn it all. For many businesses, outsourcing 3D printing is the smarter choice. It gives you access to

Introduction Magnesium is the lightest structural metal on Earth. It's about two-thirds the weight of aluminum and one-quarter the weight of steel. For industries where every gram counts—aerospace, automotive, robotics—this matters enormously. Now combine magnesium's lightness with 3D printing's design freedom. Internal lattice structures that save even more weight. Complex geometries impossible to machine. Customized

Introduction You have a great design. You've spent hours perfecting the 3D model. Now you need to get it printed. You request quotes from several services—and the prices come back wildly different. One quote is $50, another is $200 for what seems like the same part. Which one do you choose? The cheapest? The fastest?

Introduction The automotive industry has always been about efficiency, precision, and innovation. For over a century, car parts have been made the same way—casting, forging, machining. These methods work, but they have limits. Casting requires expensive molds. Change a design? Make a new mold. Forging needs massive presses and custom dies. Machining wastes material—sometimes 80%

Introduction For centuries, manufacturing meant one thing: making the same thing over and over. Economies of scale demanded it. Tooling costs required it. If you wanted something unique, you paid a premium—often an unaffordable one. Customized 3D printing changes everything. By building objects layer by layer from digital files, it makes uniqueness affordable. Each part

Introduction Selective Laser Sintering (SLS) is one of the most powerful technologies in 3D printing. It builds parts from powder, using a laser to fuse particles together layer by layer. Unlike FDM printers that squirt melted plastic, SLS creates parts that are strong, durable, and complex. No supports needed. Internal channels possible. Moving parts printed
