A 3d printer is a machine. A machine at your service…
Without a model, it won’t work!
Its computer part is waiting for instructions in the form of a file with a precise format to start printing.
A simple pencil will not be enough, it is necessary to integrate the volume and create a mesh that is all the more precise as the part to be made has a complex surface.
Choose a model
In fact, there are several ways of doing this
The 3d scanner
It is used to raise the surface of a volume. It can be any everyday object, or a model made in the workshop and that one wishes to reproduce individually or in series.
An interesting feature is that you can play with the scale and increase or decrease the size at will. Hello Russian dolls!
The online offer is quite large from very cheap to sophisticated. You can also use apps for smartphones.
To help you in your choice :
Primante3d, a very professional and complete website.

Create your own 3d model
Thanks to Jonathan Keep for his remarkable work, by a talented ceramist.
A very good starting point, very well documented.
For our part we use Sketchup (exists in free version) quite easy to use.
Fusion 360® from Autodesk and Rhino-Grasshopper® are more difficult to access but allow a great freedom of shapes particularly adapted to ceramic creativity.
In association with 3dPotter, Emmerging Objects now offers the subscription-based online software Potterware, which lets you create your own models with virtually no learning curve: no need to know 3d software to start printing! It’s all in one interface. Just great!
Be careful: if you’re going to do 3d drawing, start by practising on very simple shapes !
From model to print
The 3d printer works in successive layers. Once the model has been made, it must therefore be cut into as many “slices” as necessary. This is the work of the French “slicers” slicers.
Don’t panic! Most 3d drawing softwares have an export function in .stl format, the format that the printer can read.
We are happy, you know what!
