Your part

Upload the finished part you want in carbon (a cover, panel, fairing, dish, box, scoop…). The mold reproduces its OUTER surface.

Layup opening

The open side must face UP — that's the direction the cured part pulls out of the mold.

Mold

Release draft

5°

Tapers the cavity so the part releases. ~5° releases regardless of layer direction; higher slightly tapers the part.

Flange & wall width

12 mm

The flat rim around the opening — trim the carbon overhang against it.

Base thickness

8 mm

Parts

Split the mold along a vertical seam for big molds or easier printing. Auto splits when the footprint tops ~200 mm. Glue the halves after abrading.

Add locating dowels on the seam

Advanced

Part scale

100%

Scale the part before molding (e.g. to add a shrink allowance).
