Design your own custom pot form with a simple 2D sketch, or use one of our predesigned forms. Just 3D print the pieces, assemble them and pour plaster. You have a brand new slip casting mold!
Shape Cast has molds for handles for purchase, examples of pot forms you can print, and the ability to design your own forms as well.
Sign up for Shape Cast. You will get access to predesigned pot forms, the ability to create your own forms, and access to purchase handles.
These are examples created with Shape Cast. Each starts with a profile sketch (left) and Shape Cast renders a live 3D preview. Drag it around - it moves! Shape Cast creates the files to 3D print a mold for plaster so you can slip cast the associated form. Sign in to download the associated files to 3D print!

Select your wall thickness ►
. mmSelect the approximate wall thickness of your final ceramics piece.
Select a clay shrinkage factor ►
. %FL - Fired Length. This is the dimension of the pot once finally fired. It should also the dimension represented in the SVG file.
OL - Original Length. This is the dimenstion of the wet clay. It is also the size of the slip casting cavity.
TS - Total Shrinkage. (1 - (FL / OL)) * 100
For example, if the fired diameter is supposed to be 100mm (FL) and the corresponding mold diameter (OL) is 115mm then the shrinkage is (1 - (100/115)) * 100 = 13%.
A different example: If the fired diameter is supposed to be 80mm (FL) and the corresponding mold diameter (OL) is 94.2mm then the shrinkage is (1 - (80/94.2)) * 100 = 15%.
Create outer molds? ►
Would you like Shape Cast to create outer molds?
Yes: parts for the outer mold and bottom ring are generated.
No: You will use your own container for plaster.
If outer mold parts are selected, they will have ridges and grooves added so they can be assembled with binder clips.
Shape Cast handle molds are for sale. These are two part plaster molds (one for each half of the handle). Symmetric molds (the handle shape is mirrored top to bottom) need two copies of the same plaster mold. Asymmetric molds need two different plaster parts (one for the left and one for the right). Each plaster part needs four 3D printed parts - bottom, two different side walls, and the handle shape itself. For a symmetric mold, the four 3D printed parts can be reused twice whereas the asymmetric mold needs a total of eight printed pieces. These all assume a 13% clay shrinkage rate (so your final sizes will vary based on that). Also note that these molds have features that are very specific in size so the mold parts fit together so scaling the files is NOT recommended.
Just like other Shape Cast molds, you go straight from 3D print to plaster without silicone or other materials.
D Shaped Handle Set
We have a set of 10 D shaped handles with different heights. They range from a final height (H) of 50mm to 100mm (~2" to ~4") measured from outside to outside. They extend out 35mm (1 3/8") but are easy to trim shorter if desired when attaching to your pot. These all have the same cross section profile. See the image for the dimensions.

Ear Shaped Handle Set
We have a set of 10 ear shaped handles of two different widths (45mm and 55mm) and 5 different heights. Shown above is a handle 55mm wide (1 1/8") and 90mm tall (3 1/2") measured from the bottom where it connects to the mug to the top of the curve. For this handle, the distance between the handle attachment points (untrimmed) is about 75mm (~3"). (The other sizes have a similar change). The ends of the handle are intentionally extended out long so they can be trimmed to match a variety of pot forms. These handles have a cross section profile of 22mm wide and 8mm thick. As asymmetric handles, each requires printing 8 different mold parts (4 for each plaster half).
