BCN3D introduces autocalibration for its AM machines

January 14, 2022

BCN3D, Barcelona, Spain, has introduced a new method of autocalibration for its Additive Manufacturing machines. The new electronics system controls a piezoelectric sensor, mounted on the buildhead between the hotend and x-axis, which detects pressure to accurately measure the exact distance between the nozzle tip and the build surface.

According to the company, one of the best usages for this sensor is mesh mapping (measuring the flatness of the build surface). To carry this out, the toolhead moves along nine points, distributed across the build plate, in order to configure the most accurate Z alignment.

Autocalibration also carries out another process in an effort to ensure the perfect XY alignment for BCN3D’s dual extrusion system; at the back of the build plate, a square perimeter is used to calculate the perfect offsets between the two toolheads, eradicating any risk of crossover in a dual build.

These automatic processes collectively mean build set-up time may be reduced from forty to six minutes – a reduction of 85%. By removing human criteria, the possibility of errors and build failures are said to be reduced and BCN3D guarantees a correct first layer adhesion with each use.
