About the Process

Hand polishing is a manual process where the part is sanded, then buffed on a set of abrasive wheels or rouges to achieve the desired surface finish. This is a subtractive process that removes material in order to eliminate scratches and other imperfections.

Design considerations

  • Radiused corners and edges generally produce better results than sharp ones
  • Wall thicknesses less than 1.5mm do not hold up as well during polishing
  • Internal or hard to reach features (including threads) are difficult or impossible to polish
  • Very tight tolerances, reamed holes, and threads may need to be excluded from polishing

Prototyping Lead Time: Process Timelines and How to Reduce Delays

Prototyping lead time is often framed as a simple question: “How long will it take to get my part?” In reality, the answer is rarely determined by machine time alone. A prototype expected in days can easily take weeks—not because of production constraints, but because of delays in quoting, design iteration, manufacturability feedback, and supplier […]
