What Post-Processing Surface Finishes Are Available for 3D Printed Parts?
XC Machining provides various post-processing options to enhance the surface quality, durability, and aesthetics of 3D printed parts.
Sanding removes layer lines from FDM and SLS parts using 120–400 grit abrasives, achieving Ra 1.6–3.2 μm. Prepares surfaces for painting, plating, or assembly. Most cost-effective post-processing method.
Polishing achieves Ra 0.2–0.8 μm gloss finish on SLA resin parts and sanded FDM/SLS parts. Used for visual prototypes, master patterns, and marketing samples requiring presentation-grade surface quality.
Nickel or chrome electroplating deposits 5–25 μm metal layer on 3D printed ABS or SLA parts after conductive primer application. Provides real-metal surface appearance, EMI shielding, and corrosion protection on plastic printed components.
Spray painting with primer + topcoat on 3D printed parts provides RAL/Pantone color matching, UV protection, and cosmetic finish for consumer product prototypes, trade show models, and functional housings.
Vapor smoothing exposes ABS or Nylon SLS parts to chemical solvent vapor that melts surface layer lines, achieving Ra 1–2 μm semi-gloss finish with sealed, watertight surface. Ideal for fluid-handling ducts and cosmetic enclosures.
Stress relief and HIP (Hot Isostatic Pressing) heat treatment for SLM metal parts eliminates residual stress from laser melting, increases density to 99.9%, and improves fatigue life by 30–50%. Required for aerospace and medical metal 3D printed components.

3D Printing Frequently Asked Questions
What 3D Printing Technologies Does XC Machining Offer?
XC Machining offers five 3D printing technologies: SLS (Selective Laser Sintering) — Nylon powder fusion for functional parts and batch production, SLA (Stereolithography) — UV resin curing for fine-detail visual prototypes and dental models, FDM (Fused Deposition Modeling) — thermoplastic extrusion for large parts, tooling, and ULTEM high-temp applications, MJF (Multi Jet Fusion) — HP infrared powder fusing for end-use Nylon production parts, and SLM (Selective Laser Melting) — metal powder laser fusion for functional stainless, aluminum, titanium, and Inconel parts.
How Do You Select the Right 3D Printing Material for Your Application?
Material selection depends on: (1) mechanical requirements — tensile strength (PA12: 48 MPa, ULTEM: 81 MPa, Ti64: 1,100 MPa), (2) operating temperature — PA12 up to 175°C, ULTEM 1010 up to 216°C, (3) chemical exposure — PA11 and 316L resist most chemicals, (4) flexibility — TPU Shore A 88 for elastic parts, and (5) surface quality — SLA resins achieve Ra 1.5 μm directly off the printer. XC Machining engineers recommend the optimal material during DFM review.
What Layer Resolution Does Each 3D Printing Technology Achieve?
Layer resolution by technology: SLA — 25–100 μm (finest detail, smoothest surface at Ra 1.5–3 μm), MJF — 80 μm (consistent fine detail with Ra 6–10 μm), SLS — 100–150 μm (functional detail at Ra 6–10 μm), SLM — 30–60 μm (metal parts with Ra 6–15 μm), FDM — 100–300 μm (largest layer range, visible layer lines at Ra 10–25 μm). Finer resolution increases print time and cost but produces smoother surfaces and sharper features.
How Durable Are 3D Printed Parts Compared to Injection Molded or CNC Parts?
SLS Nylon PA12 (48 MPa tensile) approaches injection molded Nylon in strength. SLM Titanium Ti-6Al-4V (1,100 MPa) matches wrought titanium. FDM ULTEM 9085 (72 MPa) is FST-certified for aerospace interiors. Durability optimization: (1) orient parts so layer lines are perpendicular to primary load direction, (2) increase wall thickness to 1.5× minimum, (3) apply heat treatment to SLM metal parts for stress relief, and (4) use vapor smoothing on SLS Nylon to seal surface porosity and improve fatigue life.
When Should You Choose 3D Printing Over CNC Machining?
Choose 3D printing when: (1) the part has complex geometry impossible to CNC machine (internal channels, lattice structures, organic shapes), (2) no tooling investment is acceptable (prototype or 1–100 parts), (3) lead time under 5 days is required, or (4) material waste must be minimized (3D printing uses only the material needed). Choose CNC machining when: tolerances tighter than ±0.1 mm are needed, production-grade metals are required, or quantities exceed 100 parts. XC Machining offers both — engineers can prototype in 3D printing and transition to CNC for production.
