Key Specifications

Diameter: 38.15

Thickness: 3.05 mm

Maximum Relief Depth: 0.55 mm

Software: 3D relief generated with MINTFORGED

Features & Highlights

Fine Detail: The 0.55 mm relief captures crisp features without sacrificing print reliability.

Flat Back: Ideal for framing, embedding in displays, or gluing onto plaques.

Scalable: Uniformly scale up to 150 % (57 mm Ø) or down to 50 % (19 mm Ø) with proportional relief.

Universal Compatibility: Ready for any FFF/FDM printer with a minimum build area of 40 × 40 × 5 mm.

Printing Recommendations

Layer Height: 0.1–0.15 mm for optimal relief fidelity

Walls: 3 perimeters to sharpen edges

Infill: 10–15 % gyroid or grid for lightweight strength

Temperatures:

PLA: 200–205 °C nozzle / 55 °C bed

PETG: 240 °C nozzle / 70 °C bed

Orientation: Print flat (relief upward) — no s needed

Post-Processing Tips

Lightly sand with 400-grit paper to smooth any layer lines.

Apply a thin primer coat to enhance detail before painting or plating.

Seal with clear varnish or metal leaf for a finish.

Show off the power of MINTFORGED’s relief engine and add this elegant, collectible coin to your Cults3D portfolio!

Settings & Manufacturing Instructions

Printer compatibility: Any FFF/FDM printer with at least a 40 × 40 × 5 mm build volume

Nozzle & Bed

Nozzle diameter: 0.4 mm (0.25 mm if you want extra crispness)

Bed surface: glass/PEI/BuildTak with glue stick or blue tape for reliable adhesion

Filament Recommendations

PLA: Best for fine detail and easy printing

PETG: More durable and slightly glossy finish

ABS: Use if you need heat resistance (enclosure required)

Layer & Perimeter

Layer height: 0.1–0.15 mm to faithfully capture the 0.75 mm relief

Perimeters (walls): 3 shells for sharp edge definition

Infill & Speeds

Infill: 10–15 % (gyroid or grid) for a balance of strength and material savings

Print speed: 30–50 mm/s (slower speeds yield cleaner relief details)

Temperatures

PLA: 200–205 °C nozzle / 55 °C bed

PETG: 235–240 °C nozzle / 70–75 °C bed

ABS: 240–250 °C nozzle / 90–100 °C bed (use enclosure)

Orientation & s

Lay the coin flat on the build plate (relief facing up)

No s needed for the basic round coin—ideal CM geometry

Scaling

Uniformly scale X/Y in your slicer to maintain the 1 : 1 aspect ratio.

If you increase Z (thickness), relief depth will scale proportionally (e.g., at 200 % Z you’ll get 1.5 mm relief).

Post-Processing

Lightly sand edges and relief peaks with 400-grit paper to remove any fuzz.

Apply a thin coat of primer or filler-primer to bring out fine details before painting.

Optional: metal-leafing or metallic spray for a coin-like finish.
