Design Concepts

This model features a scale representation of the planets in our solar system. The detailed textures and accurate proportions make it ideal for educational purposes or as a decorative piece.

Purposes

It serves as a learning tool for astronomy enthusiasts and educators to demonstrate the planet arrangements and their sizes in comparison to one another.

Printing Recommendations

Consider printing the model with a high-resolution printer to capture all the detailed textures. Multi-color or dual-extrusion printers can enhance the visual appeal by distinguishing each planet with its own distinct color.

Assembly Instructions

If the planets are printed separately, they should be assembled in order starting from Mercury to Neptune for educational or display purposes. Use a strong adhesive for a more permanent display setup.Layers and Quality

Layer Height:

0.2 mm → good quality/time compromise ✅

0.12–0.16 mm → more detail (recommended for fine relief)

Line Width: Standard (0.4 mm)

Infill

For wall art, no infill is needed:

10–15% infill

Pattern: Gyroid or Grid

If it's thin: even 0% (walls only) is fine

Walls and Top/Bottom

Walls: 2–3 (0.8–1.2 mm)

Top/Bottom: 4–5 layers

👉 Improves strength without weighing it down

Speed

50–60 mm/s (standard)

If you want more quality: 40 mm/s

Print Orientation (very important)

For wall art:

Print flat on the plate

"Beautiful" side up

Use a light brim (3–5 mm) if the Surface is large

❌ Avoid printing vertically: it degrades quality and increases the risk of failures.

Supports

NO supports, if possible

If there are overhangs:

Supports only from the bed

Low density (10–12%)

Temperature (PLA)

Nozzle: 200–210°C

Bed: 55–60°C

Fan: 100% from the 2nd–3rd layer

Post-processing (recommended)

For a true wall art effect:

Sand lightly (220 → 400 grit)

Spray primer

Acrylic or matte spray paint

Optional: Matte clear coat for a premium finish
