The Challenge

Scaling a 10cm figurine to 180cm isn't just multiplication — it's a complete re-engineering of the print strategy.

Splitting the Model

I used Chitubox to split the model into 47 pieces, each fitting within a 250×250×300mm build volume. Every joint was designed with a 0.3mm tolerance for a friction fit.

Material Choice

PLA+ for the main body (strength + slight flexibility for assembly), PETG for the joints (better layer adhesion under stress).

Print Farm Setup

I don't have a print farm — just three Bambu Lab X1C units running 24/7 for 22 days. Total filament used: 18.4kg.

Assembly

The internal skeleton is 20mm aluminum square tube. Each printed panel clips onto the frame with M4 bolts hidden behind panel lines.

Finishing

  • Filler primer × 3 coats
  • Wet sanding to 1500 grit
  • Automotive base coat (Gunmetal Grey)
  • Airbrushed panel shading
  • Gloss clear coat

The Result

The finished Mech Titan X stands at my front door. It's been featured in two local news articles and drove 340 new followers to my Printastic creator page.
