．Development Background
Thanks to the SLS Sinterit Lisa printer, ELECTOR can create test prototypes of voting machines faster and easier. The final product is now used for voting in various government agencies, committee meetings, and management tests and questionnaires during lectures and conferences. ELECTOR specializes in developing wireless voting systems for voting, automatic vote counting, and instant graphical presentation of results. From a design perspective, the company wanted equipment that was both functional and aesthetically pleasing, so they decided to use Sinterit Lisa to produce 3D printed prototypes to complete the voting machine design faster and better.
．Challenges Faced
"Our goal was to create the best physical effect for the handheld voting machine; we wanted to incorporate our years of ideas, modifications, and experience with components into the production process, while maintaining low cost and a lightweight, compact size. In the past, we made time-consuming adjustments, cutting, drilling, and fitting improvements to commercially available housing modules; the results still lacked ergonomics and aesthetic design. When we decided to develop a new project, we had difficulty grasping certain design variables, such as: proportion and shape, the feel in hand, and the placement and size of components like labels and logos.
Significantly reducing production time and user-friendly operation are also important. We designed several special structures and latches on the casing to integrate our IC boards, keyboards, batteries, casing, and LEDs.
Depending on the production scale, we would have to use plastic injection molding and develop molds; however, considering the very high development cost, we needed to use a cheaper technology to repeatedly modify prototypes before finalization."

．From Proposal to Product
The first step was to create a 3D model of the new proposal, with multiple design iterations and modifications on the computer; then, moving to the 3D printing stage to gather real user feedback. ELECTOR later used Sinterit Lisa for 4 additional 3D prints to refine design details until they were satisfied with the shape and structure of the new casing before proceeding to mold production.
By being able to produce and refine prototype samples within hours, 3D printing can significantly shorten the design, testing, and development phases. Using SLS Sinterit 3D printing for rapid prototyping allowed ELECTOR to make multiple modifications in a shorter time, thereby enabling thorough testing while also reducing time-to-market.
Using Sinterit Lisa for 3D printing allowed them to truly understand the appearance and performance of their product before investing in it. This gave the voting machine several features: a more user-friendly appearance and operation, faster and easier production processes, a flexible battery cover produced simultaneously with the casing in a single mold, multiple products that can be stacked, and recessed label grooves on the side of the casing.
