Bi-Uni Convertible Bicycle

Material: ProtoFab Formula L1 Resin
Production technique: SLA 3D printing
Precision: 0.01 mm

Lead time: 3 days
Client requirements: Solid construction, High-quality post-production

Project Background

We were contacted by the organizing committee of the 2017 Cross-Strait Industrial Design Awards with a request to provide professional prototype production for each of the competitors. With high-quality models produced for each of the products taking part, it would be much easier for them to show off their innovation and ingenious design.

Project Analysis

On receiving the client’s drawings and requirements our design team promptly began their analysis, assessing the feasibility of the project and discussing minor adjustments to the construction. Due to the complexity of the design, it was decided that using CNC machining would result in excessive material, equipment and labor costs, as well as being too time-consuming. Due to this, our team selected SLA 3D printing as the way forward for the project. Not only would this be significantly quicker than CNC, it would also make post-processing more straightforward. Below is the drawing the client sent us.

Challenges

Solutions

With such a complex design involving so many small parts, prior to printing it was necessary to divide the model up into sections which would be printed separately and then later assembled. Using software, we were able to optimize the assembly process and check for any potential issues with the design. The images above show the results of our computer analysis with the model divided into different sections, each signified by a different color.
