What we brought

  1. What we can do

    Parts too tall for one print

    The 478 mm mould is printed in two halves and joined with stainless screws into nuts set inside the walls.

  2. How we look after you

    We start on your line

    We visited Commonwealth's bagel line before drawing, then reworked the stamp through four designs on their feedback.

  3. What you get

    A new size for the same machine

    A medium mould for the machine that runs their small and large ones, plus four clear cookie stamps.

The brief

Step 1 of 5

Machine
The same bagel line as their small and large moulds
Material
Their moulds are food-grade PE100. 3D prints are not food grade, so a food-contact mould would be vacuum cast or CNC machined

Also asked for
A cookie stamper with a clear acrylic disc

At Additive Inn, our 3D printing studio in Singapore, we designed a mid-size bagel mould and a cookie stamper for Commonwealth Culinary Creations. Their bagel line ran small and large moulds; they needed a medium one for the same machine.

Design & prototyping

Step 2 of 5

We modelled the mould from Commonwealth's measurements and our site visit. At 478 mm it is split down the middle so it can be printed, with nuts set into the walls. The stamp began as a 150 mm acrylic disc under a printed handle.

    Curved printed feet now follow the rim, and the handle screws through the acrylic into them.

Production

Step 3 of 5

The mould halves were printed in white PLA at 90% infill, one medium set and one large. The stamp handles and feet were printed in black, and the 5 mm discs cut from clear acrylic.

Build & assembly

Step 4 of 5

Each pair of halves was joined with 316 stainless steel M5 screws into nuts set in the print. On the stamps, the handle screws through the acrylic into the curved feet below.

Commonwealth Culinary Creations collected a medium and a large bagel mould and four cookie stamps, each a clear acrylic disc under a matte black handle.
