The difference between a plastic toy and a professional piece is finishing. Learn the six-phase process used on every high-detail model in this catalog.

Before any finishing work begins the print must be properly cleaned. Rushed prep is the most common reason a finished piece looks worse than a raw print - oils from your hands contaminate primer, and poorly removed supports leave stress marks that show through paint.
Use flush cutters, not pliers. For intricate models like the Gothic Gargoyles, always cut supports away from the model - never pull them. Pulling tears surface detail with it. Cut close to the model body and clean up remaining nubs with a hobby knife.
White stress marks from support removal can be eliminated instantly with a quick pass of a heat gun held 3-4 inches away. The surface re-melts and the mark disappears. One-second passes only - lingering will warp the part.
Wipe the entire print with isopropyl alcohol (90%+) before sanding or priming. Finger oils bond to PLA and create fisheye defects in primer. Wear nitrile gloves from this point forward.
The soap wash: For prints that will receive paint, wash with warm water and Dawn dish soap, then dry with a lint-free cloth. This removes release agents from the build plate surface that IPA alone misses.
Sanding is what separates a "3D printed thing" from a professional prop. It is not optional for painted pieces. Use this grit progression for PLA and PETG:
| Grit | Purpose | Method |
|---|---|---|
| 120 - 220 | Remove heavy layer lines and support scars | Dry sand |
| 320 - 400 | Smooth the surface after initial filler primer | Wet sand |
| 600 - 800 | Final prep before color coat | Wet sand |
| 1000 - 1500 | Polish clear coats and metallic finishes | Wet sand |
| 2000+ | Final polish for gloss and transparent parts | Wet sand |
Wet sanding is mandatory above 320 grit. Dry sanding at fine grits generates friction heat that turns PLA surfaces gummy. Keep a spray bottle of water nearby and use light circular pressure - you are polishing, not cutting.
Even after sanding, layer lines remain in the valleys between peaks. Filler primer and UV resin bridge those gaps before paint. Skipping this step is visible in the final finish.
Spray a heavy coat, let cure 30 minutes, then sand 90% away with 400-grit wet. What remains in the valleys makes the surface optically smooth. Repeat 2-3 times for a flawless base.
For deep seam gaps on multi-segment props, brush on clear UV resin, cure with a UV light for 60 seconds, sand flat with 220-grit. Faster and structurally stronger than wood filler or putty.
For visible pinholes after the first primer coat, apply automotive spot putty with a finger. Let cure 10 minutes, sand with 320 wet, then prime over. Disappears completely.
Color your primer: Use grey filler primer for dark final colors, white for light final colors. Using grey under white paint requires 3-4 more color coats to cover. This single decision saves an hour per piece.
Always use a dedicated plastic primer before your color coat - standard spray paint can craze or peel on raw PLA without it. For metallic finishes like the Industrial Pipe Bookends, start with a gloss black base coat. The dark base gives metallics a depth and shadow that white or grey cannot match.
Hold the can 10-12 inches from the surface, use overlapping passes, and never stop moving while the trigger is held. Multiple thin coats beat one heavy coat - runs are permanent defects that require sanding back.
For production-level results and complex gradients, use an airbrush. Thin acrylic paints 1:1 with airbrush thinner. 15-20 PSI for detail, 25-30 PSI for basecoats. Clean immediately after each color.
Always seal finished paint with a clear coat matched to your finish - matte for realistic pieces, satin for props, gloss for display models. Clear coat protects the paint from handling wear and fingerprints.
Weathering adds the history a piece doesn't have. A prop that looks like it's been used is more convincing than one that looks factory-fresh. These two techniques cover 80% of weathering needs.
Mix 50% black acrylic paint with 50% water. Brush the thinned mixture over the entire model. Wait 30 seconds, then wipe raised surfaces clean with a paper towel. The diluted paint settles into every recess, dramatically enhancing carved detail depth. This is the primary technique for the entire Gothic Noir collection.
Rust and oxidation effects: Apply a base coat of dark brown, let dry, then dry-brush copper or orange-red on raised surfaces. Follow with a thinned green or blue-grey wash pooled into the recesses. Reads as genuine patina from 3 feet away.
Multi-segment prints require the right adhesive for the use case. Using the wrong adhesive on a prop that gets handled is the most common cause of joint failure at conventions.
Standard cyanoacrylate for PLA-to-PLA bonds. Use a gel formulation to prevent drips on finished surfaces. Add activator/accelerator to cut cure time from 60 seconds to 5. Best for small seams and rigid assemblies not under load.
Essential for large-scale props like the Celestial Archangel Glaive or any piece that sees repeated handling. Creates a chemical bond that won't fracture under flex stress. Mix equal parts, clamp 5 minutes, full cure in 24 hours.
For staff and weapon props over 24 inches, insert a 1-inch schedule 40 PVC pipe through the handle cavity before final assembly. Adds structural rigidity at zero weight cost. Prevents handle fracture - the most common failure point for convention props.
Seam hiding after gluing: Fill any visible seam with spot putty, sand dry, touch up with your base coat color. On painted pieces the seam becomes invisible. On unpainted pieces, apply a thin bead of CA glue along the seam, sand flush with 400-grit wet, then clear coat.
