The Challenge

A consumer electronics company was in the late design stages of a next-generation Virtual Reality (VR) headset. Before committing over $30,000 to steel injection molds, they urgently needed five sets of highly accurate, fully functional physical prototypes. These prototypes had to be used for ergonomic user testing, internal component fitment, and a high-stakes pitch to investors. They required both structural flexibility for snap-fits and a flawless, showroom-ready surface finish.

The Printreal 3D Solution

We deployed a hybrid additive manufacturing strategy to perfectly match the material properties to the function of each specific component.

Internal Chassis & Headstrap Mounts: We used SLS (Selective Laser Sintering) with Nylon PA12. This provided the necessary high toughness, impact resistance, and flexibility required for the internal living hinges and complex snap-fit assembly joints.

Outer Aesthetic Shells: For the highly visible exterior components, we utilized SLA (Stereolithography) Standard Resin. This captured the extreme micro-details and provided an ultra-smooth surface finish.

Surface Finishing: Our post-processing team meticulously sanded and painted the SLA shells with a matte UV-resistant coating, making the 3D-printed parts indistinguishable from final injection-molded consumer products.

The Result

Flawless Validation: The hybrid prototypes assembled perfectly on the first try, allowing engineers to validate PCB clearances and lens mountings immediately.

Investor Success: The flawless surface finish and functional feel of the prototypes successfully helped the client secure their next round of funding.

Rapid Turnaround: All five prototype sets were printed, post-processed, painted, and delivered, keeping the strict product launch timeline perfectly on track.
