Machine tool

A machine tool comprising:

• A first, “lambda,” rotary motor comprising a lambda shaft and an associated lambda axis collinear with the lambda shaft;
• a second, different, “theta” rotary motor comprising a theta shaft and an associated theta axis collinear with the theta shaft, wherein the lambda and theta axes are parallel and offset;
• a build surface at a predetermined, normal distance from a fixed reference plane, wherein the build surface is adapted to accept a removably affixed part;
• wherein the reference plane is normal to the lambda and theta axes;
• a baseplate comprising an opening through which the lambda shaft passes;
• wherein the lambda motor is disposed on a first side of the base plate and the build surface is disposed on a second, opposing side of the base plate;
• wherein the lambda shaft operatively rotates the build surface around the lambda axis,
• wherein the reference plane is at a predetermined, fixed normal distance from the baseplate;
• a machine tool head;
• a connection arm affixed at a proximal end to the theta shaft and affixed at a distal end to the lambda motor;
• wherein rotation of the theta shaft causes the lambda motor, the lambda axis, and the build surface to revolve in an arc around the theta axis;
• wherein, responsive to rotations of the lambda and theta shafts, a fixed tool head axis, normal to the reference plane, passing through the machine tool head, intersects any desired point on the build surface.
