3D printer "Duet" with 2 extruders.

cults3d

A little history and motivation. Often in design you need to print a prototype. This is a one-off model, and any 3D printer will do a good job. But there are times when you need to start making a model in series, but the number of parts is still not enough to cast. That's exactly the kind of case I developed this printer for. The main feature of the printer is that it has one Z axis, one Y axis and 2 independent X axes. When printing, we can mentally divide the bed into 2 halves and print copies or mirror parts simultaneously on the same printer. Also a feature of the development is that the X-axes are made in the form of a console. This arrangement makes it very convenient to approach the part and the whole bed. However, there is a disadvantage - it is almost impossible to print with materials that require a thermal chamber, such as ABS. Bed 300x200. Consumption of 400W. The model is made in NX. How to make the construction parts - everyone decides himself, 3D printing, milling, turning and so on. And there is an export of the model to STEP, STL, X_T. There is a separate printer configurator, setup files, firmware and board documentation. However, any board is applicable, not only the used one.
