A model is ready for large-scale printing when the mesh is closed, the surface has real thickness, the seams can go somewhere sensible, and there's a plan for what holds it up from the inside. You don't have to solve all of that yourself: we section and engineer every large piece. But a model that starts in good shape gets to a quote and a schedule faster.
Room-scale pieces aren't printed solid or in one go. They're printed as shells, in sections, then joined and finished so they read as a single object. That changes what matters in the file.
| Check | What we look for | Why it matters at scale |
|---|---|---|
| Closed mesh | No holes, flipped faces or overlapping bodies | Open meshes can't be sectioned or shelled reliably |
| Real units | Model at true size, or a stated target height | A model in the wrong units can be 25 times off |
| Detail vs size | Fine detail is fine; tiny features scale with the piece | A 2 mm crease on a 30 cm model becomes a 2 cm groove at 3 m |
| Seam lines | Natural breaks: edges, colour changes, undersides | Seams on edges disappear; seams across smooth curves need more filling |
| Inside | Where the frame, base plate or rigging goes | Decides shell thickness and section layout |
Think in shells
Solid large prints would be heavy, slow and expensive. We print a shell with internal ribs where it needs stiffness. If your piece will be sat on, hung, or touched by crowds, say so: that drives the shell thickness and whether it needs a steel or timber frame inside.
Let the seams follow the design
Every big print is cut into sections. If the design has natural breaks, like the edge of a keycap, the seam of a wrapper or the neck of a light bulb, that's where the cuts go, and the finished piece needs less filling and sanding. If you have a preference, mark it on the render.
Scale changes the detail
Everything scales together. Surface texture that reads as subtle on screen can look coarse at three metres, and thin parts that are fine at desk size need reinforcement when they're longer than a person. Send the target size with the file and we'll flag anything that won't hold up.
Plan the fixings
Bolting to a floor, hanging from a ceiling, or sitting on a weighted base all need hard points inside the print. Tell us how the piece will be mounted and we design them in.
