How to Print a Big RC Boat Hull on a 250 mm Printer
You don't need a giant printer to build a 4-foot boat. Our big hulls print on a large-format machine in our shop, but many TMRC packs also come split into sections that fit a standard 250 x 250 mm bed.
Packs with a split version included
| Pack | What's in the download |
|---|---|
| Freedom 56 | Full-size + 250 mm split |
| Reaper 47 | Large-format + 250 mm split |
| 42 Offshore | Large-format + 250 mm split |
| Calypso 36 | Large-format + 250 mm split |
| SeaVee 322Z | Split hull sections |
| Lynx 36 Cat | 250 mm version included |
| Viper 37 (pre-order) | Prints on a 250 mm bed |
| Legacy 30 | 290 mm + 250 mm versions |
| Raptor 30CC | Split for 250 mm |
The Mangrove Cat needs a 295 x 295 mm bed. Every product page lists what's in that pack, so check it before you buy.
Older packs: split it yourself
If a pack doesn't have a 250 mm version, you can still print it. Split the hull in your slicer, print the pieces and glue them back together.
- Open the hull section in your slicer and use its cut tool (Bambu Studio, OrcaSlicer and PrusaSlicer all have one).
- Cut across the hull, not along it, so each seam runs side to side.
- Turn on connectors or dowels if your slicer offers them. They line the pieces up when you glue.
- Keep seams away from the transom and motor mount, where the load is.
- Print every piece with the same settings and filament so they match.
Gluing the sections
Glue with CA or epoxy, clamp the pieces square and let them cure fully. Then fill and sand the seams before paint. Seal the inside of every seam: that's where water gets in (see our sealing guide).
How long it takes
A big build is a project. Large hulls run 100 to 230+ hours of printing in total, and more sections means more glue-ups. Print one section first to check fit before you commit to the whole boat.
