A machine tool incorporating two angular axes as an inverted SCARA arm and a vertical, linear Z-axis, is described. A build surface on which a 3D object may be additively built is rotated around a lambda axis and also revolved around a theta axis. Embodiments are described that: (i) are free of belts, pulleys, cables and other soft drive mechanisms; (ii) place all three axis motors below a base plate; (iii) direct drive the build surface from shafts of a lambda and theta motor; (iv) are free of a rectangular box frame; (v) use angle sensors mounted directly on motor drive shafts; (vi) measure and compensate for build surface skew; (vii) incorporate a single element for both Z-axis support and a bearing surface. Both device and method embodiments are claimed.
