Over the last five years, two main advances have helped additive manufacturing (AM) evolve from a prototyping technology to a viable production method. The first is in material development, where ...

Although everyone knows that plastic injection molding can produce mass volumes of parts with precision and low cost, not every manufacturer gets the process right, which could defeat its purpose and ...

Editor's Note: An updated version of this information can be found here. What exactly is computer-numerical-controlled (CNC) machining? It’s a means to make parts by removing material via high-speed, ...

In part one of this two-part article, design engineer Michael Paloian outlined the first four milestones of a product-design project, ending with the “cornerstone” of the product-design cycle — ...

There are thousands of designers who design injection molded parts but there is an elite group within this large community who can actually design parts for injection molders. Injection molded product ...

Injection molding is a highly-engineered process that demands careful planning and attention to detail if the finished product is to achieve its full potential. The tips in this article should help ...

Part design entails more than just sketching a part from idea to final product – The designer’s challenge is to select a material, understand performance requirements, environmental conditions and a ...

当一个元件封装包含多个相对独立的功能部分（部件）时，可以使用子件。原则上，任何一个元件都可以被任意地划分为多个part（子件），这在电气意义上没有错误，在原理图的设计上增强了可读性和绘制方便性。 子件是属于元件的一个部分，如果一个元件被 ...

OpenSCAD has a lot of fans around these parts — if you’re unaware, it’s essentially a code-based way of designing 3D models. Instead of drawing them up in a CAD program, one writes a script that ...
