How to Design Wire Guides that are Functional and Beautiful

A robot performing parkour was impossible 30 years ago, but now, Boston Dynamic’s Atlas robot can traverse an obstacle course gracefully and precisely. Boston Dynamics uses Atlas as an exercise to unlock the next generation of mobility, perception, and athletic intelligence in robotics. The Atlas robot is constructed of a beautiful combination of 3D-printed titanium […]

Guide to Foamcore Joining Techniques

Foamcore (also known as foam board or foam core) is a lightweight building material typically consisting of an inner foam layer sandwiched by paper or another thin, lightweight material. If you have put together a poster for a school project or a work-related presentation, odds are you’re familiar with rigid foam core poster board. Foamcore […]

Types of Springs and their Applications: An Overview

Springs are common in all kinds of machines — from consumer products to heavy industrial equipment. Take apart anything that involves a mechanism, and chances are, you’ll find a spring inside. Springs are storage devices for mechanical energy, analogous to the electrical storage capacity of batteries. The earliest spring-driven clocks appeared in the 1400s. Fast-forward […]

Thermoplastics vs. Thermoset Plastics: Material Properties Overview

Thermoplastics and thermoset plastics are classes of polymers used in injection molding, CNC machining, 3D printing, and urethane casting. Like elastomers, another class of polymer, thermoplastics and thermosets both consist of long, repeating chains of molecules. Under a microscope, the structure of a thermoplastic resembles a railroad track while a thermoset material looks like a […]

How to Build a BOM

Chefs create recipes. Hardware Engineers create BOMs (Bill of Materials) and SOPs (Standard Operating Procedures). The BOM is an ingredient list for building your product, and the SOP is the set of instructions on how to build it. In this article, we’ll explain how to construct an excellent ingredients list that will help you clearly […]

3D Printed Light Pipes: Overview and Material Selection

The advent of 3D printable transparent materials has opened doors to new possibilities with rapid prototyping for optical applications. Now, we can consider how to use and manipulate light with 3D printed parts. Light pipes, sometimes referred to as light guides or light tubes, are physical components used to purposefully redirect or transport light from […]
