Dan Topjian’s Carbon‑Fiber Business Card Holder – A Markforged Showcase

Dan Topjian is the Senior Applications Engineer at Markforged, where he guides clients in integrating additive manufacturing into their production lines.

Why a Business Card Holder?

When Dan visits a customer, he wants an immediate visual cue that sets him apart. The carbon‑fiber reinforced business card holder serves that purpose—functional, eye‑catching, and a testament to what the Mark One can achieve.

Design Highlights

Designed in OnShape, the holder incorporates two signature features made possible by the Mark One:

1. The front logo is printed behind a clear plastic insert using MarkForged’s over‑printing technology. The print pauses, the logo and insert are added, then the process resumes, fusing the layers for a secure, translucent finish.
2. Threaded inserts, hex screws, and a magnetic cover give the holder exceptional strength and easy assembly.

Materials and Build

Each of the three parts is made from nylon and reinforced with carbon fiber, yielding a lightweight yet robust structure. The Plexiglass insert keeps a single business card permanently encased, ensuring Dan never runs out of cards to hand out.
