The Fast Radius
The WRIST RESt: THE BASICS
Almost amazing as the wrist rest itself is the fact that we made it in just 7 days; all the way from initial concept to final print. We designed, printed, and tested four prototypes, finally settling on a wrist rest with the following properties:
Material: EPU 40
Size: 76mm x 136 x 25mm
Weight: ~ 50g
Latticing software: nTop Platform
Primary lattice unit cell: Body-Centered
Print time: ~80 min
Designing the wrist rest.
A step-by-step guide to latticing.
The steps below walk you through how we optimized the design of our wrist rest for ultimate usability and comfort.
Start by creating the base part geometry to be filled with the lattice and other design elements. This allows the shape and geometry to be evaluated before moving on to more refined latticing. Flat surfaces typically serve as starting points for latticing tools.
Generate the wireframe of the lattice structure that conforms to the part geometry. This wireframe consists of a repeated lattice “unit cell,” which includes connections like beams and nodes without “thickness.”
Thicken the lattice structure uniformly, with the radius of each beam around the wireframe a constant value. This approach is adequate in situations where you’re not trying to achieve a variation in stiffness.
Vary the thickness of the lattice around the wireframe by using a field-driven design approach. If you look closely, you can see a thickness gradient that spans the front to the back of the rest.
Add all non-lattice geometry to the part, including a border, logo, serialization, and a top skin for aesthetics.
