Question 1

Do I need CAD software to design a cup?

Accepted Answer

No. The cup is built from a few numbers: height, diameters, a silhouette, and an optional surface pattern. Everything runs in your browser and you download a printable STL.

Question 2

Is this the cup or the mold?

Accepted Answer

It is the master, the solid positive you cast from, so it is solid rather than hollow. The mold generator builds the cavity that makes the finished piece. The Use in a mold button hands the shape straight over.

Question 3

Can a cup with a handle be cast in a two-part mold?

Accepted Answer

No. A handle encloses a hole, and no two-part mold can form a through-hole. Cast a handled cup in a cut-open silicone mold, or split the mold into three parts. The designer says so as soon as you switch the handle on.

Question 4

How much concrete will the cup need?

Accepted Answer

The designer shows the volume of the shape as you change it and converts it to a rough weight of concrete. That is the solid master, so the finished hollow cast uses less.
