When it comes to post-processing 3D printed parts—whether FDM plastic prototypes or resin SLA models—the finishing step can make or break the final look. Precision Burrs for 3D applications have become essential tools for makers and professionals aiming for a flawless surface. Craft Tech Cutting Tools already shines with its carbide burr expertise in metalworking, and now it’s leading the way with Precision Burrs for 3D finishing that deliver superior control, minimal heat buildup, and smooth results across complex geometries.
Why Burr Geometry Matters in 3D Printing
Different burr shapes and flute designs (single-, double-, or diamond‑cut) significantly impact the outcome:
-
Single‑cut cylindrical burrs excel at material removal—ideal for flattening large surfaces, but run the risk of melting thermoplastics if used too fast.
-
Diamond‑cut ball and tree burrs deliver fine finishes in enclosed details without clogging or overheating.
-
Flame and cone burrs access tight transitions and undercuts cleanly, preserving model integrity.
The right burr—and the right geometry—can overcome that.
Matching Burrs to Materials and Models
| Material / Model Type | Burr Shape & Cut | Why It Works |
|---|---|---|
| PLA/FDM — flat/broad areas | Single‑cut cylinder, large size | Fast layer removal, but use low RPM to avoid melting |
| SLA/resin — smooth surfaces | Diamond‑cut ball/tree burrs | Gentle, even finish without clogging |
| FDM supports or steep angles | Cone or flame burrs | Cleanly accesses crevices and transitions |
Smart Burr Use: RPM and Technique Tips
-
Lower RPM, light pressure: prevents plastic burning
-
Keep burrs moving: avoids localized heat accumulation
-
Use flex‑shaft handheld tools: give better control than high‑speed rotary tools—Prusa users caution against overheating
-
Sand or polish post‑burr: follow up with fine grit (e.g., 400–800), buffing or vapor smoothing for a flawless final finish
Quick Post‑Processing Workflow
-
Remove supports by hand or clipping
-
Start with single‑cut burrs to eliminate large ridges
-
Refine curves and details with diamond‑cut burrs
-
Sand with progressively finer grit
-
(Optional) Vapor smooth ABS or apply polish for a mirror finish
-
Clean parts and apply sealant/coat if necessary
