Simple tips to give your prints a smooth, pro-quality finish

If your 3D printed parts come out rough or dull, don’t worry, you can fix that! With the right finishing techniques, your parts can look clean, smooth, and ready for use. Here are 5 easy ways to make your 3D prints look better.

1. Use Vapor Polishing for a Shiny Surface

What it does: Vapor Polishing melts the outer layer of your 3D print with special chemicals.
Best for: Nylon, ABS, and other thermoplastics.
Why it works: It removes layer lines and gives the part a glossy, almost injection-molded look.
➡ Tip: Use this method for display models or parts that need to be waterproof.

2. Try Bead Blasting for a Matte Finish

What it does: Bead blasting uses fine particles to smooth your part’s surface.
Best for: Nylon 12 and parts printed with MJF or SLS.
Why it works: It creates a soft, even texture that looks clean and professional.
➡ Tip: This is great for functional parts or anything that needs a consistent finish.

3. Add Color with Dyeing or Painting

What it does: Adds color after printing, either by soaking (dyeing) or brushing/spraying (painting).
Best for: Branding, product prototypes, or custom parts.
Why it works: Adds style and helps your parts match your brand.
➡ Tip: Use professional dyes or paints to keep colors from fading.

4. Design for a Better Finish Before You Print

What it does: Good design makes your part easier to finish.
Best for: Any part you want to look smooth from the start.
Why it works: Simple shapes, rounded corners, and good support settings help reduce rough spots.
➡ Tip: Follow DfAM (Design for Additive Manufacturing) to avoid overhangs and steep angles.

5. Choose Materials That Look Great Right Off the Printer

What it does: Some 3D printing materials are naturally smoother, more detailed, and more durable.
Best for: Customers who want a professional finish with little to no post-processing.
Why it works: Materials like PA12 (Nylon 12) print with tight tolerances, smooth surfaces, and high detail, all without extra finishing steps.
➡ Tip: If you want strong parts that also look sharp, choose engineered materials like PA12 or PA11. These are perfect for functional parts, end-use products, and high-end prototypes.
