Smoothing, Painting & Epoxy Finishes

FDM Finishing

Turn visible-layer FDM prints into cleaner display pieces, painted models, presentation prototypes, and more durable finished parts.

FDM Finishing

FDM printing is strong, practical, and cost-effective, but freshly printed parts often show layer lines, seams, support marks, or small surface imperfections. Our FDM finishing services add the extra craft after printing: filling, smoothing, sanding, priming, painting, and epoxy finishes tailored to how the part will be used.

Common Use Cases

  • Presentation prototypes and investor demo models
  • Cosplay props, helmets, armor pieces, and display objects
  • Decorative home, office, and retail display pieces
  • Painted miniatures, sculptures, and themed models
  • Branded promotional pieces and awards
  • Large FDM parts printed in sections and blended after assembly
  • Functional prints that need a cleaner visible surface

Gap Filling & Surface Smoothing

We fill seams, layer texture, and small print artifacts where appropriate, then smooth the surface to prepare it for primer, paint, or a clear protective finish.

Sanding & Primer Prep

Progressive sanding and primer help reduce visible layer lines and create a cleaner base for display parts, prototypes, cosplay pieces, and decorative prints.

Painted Finishes

We can apply single-color, multi-color, metallic-look, or detail-painted finishes depending on the part geometry, project budget, and desired appearance.

Epoxy Coating

Epoxy finishes can add gloss, surface depth, and extra protection for selected FDM parts. We recommend epoxy when it matches the part shape, use case, and finish goals.

Our Process

  1. 1

    Finish Goal Review

    We confirm whether the part needs to look display-ready, paint-ready, durable, glossy, or simply cleaner than a raw FDM print.

  2. 2

    Part Prep

    Supports, rough edges, seams, and surface artifacts are cleaned up before filler, sanding, or primer work begins.

  3. 3

    Surface Build

    We apply filler, sanding, primer, and repeat passes as needed to reach the agreed finish level.

  4. 4

    Final Finish

    Paint, clear coat, epoxy, or final assembly is completed and inspected before pickup or shipping.
