About Project

At FacFox, we empower your vision for innovative wireless earbuds with our cutting-edge prototyping techniques. This image showcases a prototype of unique wireless earbuds, not your standard Airpod design, created using a combination of CNC milling and 3D printing.

• The earbuds themselves are CNC milled from aluminum alloy for a premium feel and lightweight construction.

• Internal components are secured within a precisely 3D-printed housing, crafted from black resin for a sleek aesthetic. 

We've left the machining marks visible as the client has no high requirements of appearance for the prototypes. Even with these marks, the earbuds function perfectly, showcasing a seamless fit and exceptional build quality.

CNC milling and 3D printing provide unparalleled versatility for wireless earbud prototyping. CNC milling meticulously sculpts intricate details from metal, while 3D printing builds complex shapes based on your digital design.

Our team of experts at FacFox will collaborate with you to select the ideal prototyping methods for your project. With our vast array of materials and finishes, you can create prototypes that closely resemble the final product in both form and function.

  • Step 1: Design & CAD Modeling: Begin with a detailed design of the earbuds enclosure, specifying dimensions, tolerances, and aesthetics. Use CAD software to create precise 3D models of each component.
  • Step 2: Material Selection: Choose suitable materials and techniques for each part:
    • Bottom housing: Black resin for LCD 3D printing.
    • PCB holder: Aluminum alloy for CNC milling.
    • Seal ring: Copper for CNC milling.
  • Step 3: LCD 3D Printing of Bottom Housing:
    • Prepare the 3D printer with black resin.
    • Print the bottom housing using LCD technology, ensuring high precision to maintain the integrity of the design.
    • Remove the part from the printer and clean off any excess resin.
  • Step 4: CNC Milling of PCB Holder and Seal Ring:
    • Set up the CNC machine with the appropriate milling tools for aluminum and copper.
    • Load the aluminum alloy and copper blocks into the machine.
    • Mill the PCB holder from aluminum alloy and the seal ring from copper, following the CAD design closely.
  • Step 5: Post-Processing:
    • Inspect the 3D-printed bottom housing for any supporting structure marks that need to be addressed.
    • Check the CNC milled parts for sanding marks and ensure they meet the design specifications.
    • Assemble the parts to verify fit and precision.
