Rotatable engagement of additive manufacturing build plate

An apparatus comprising:

• a rotatable member including an actuator therein, and mechanically coupled to a height adjustable platform, wherein the rotatable member defines an axial direction;
• a pair of coupling members coupled to the rotatable member, wherein each of the pair of rotatable members extends axially and substantially parallel with the rotatable member;
• a controller operatively connected to the rotatable member and configured to rotatably engage the pair of coupling members with a build plate by performing actions including:
• rotating the pair of coupling members to be substantially aligned with a respective pair of opposing sidewalls of the build plate,
• linearly actuating the pair of coupling members to engage the pair of opposing sidewalls of the build plate, and
• adjusting a position of the build plate with the pair of coupling members engaged in the pair of opposing sidewalls thereof.

A system comprising:

• a height adjustable platform;
• a rotatable member coupled to the height adjustable platform and defining an axial direction from the height adjustable platform, the rotatable member including an actuator therein;
• an alignment member coupled to the rotatable member and oriented radially relative to the axial direction, wherein the alignment member includes a first radial end and an opposing second radial end;
• a first coupling member extending axially from the first radial end of the alignment member and configured to mechanically engage a first sidewall of a build plate, wherein the first coupling member is oriented substantially parallel to the rotatable member;
• a second coupling member extending axially from the second end of the alignment member and configured to mechanically engage a second sidewall of the build plate, the second sidewall being radially opposed to the first sidewall, wherein the second coupling member is oriented substantially parallel to the rotatable member;
• and
• a controller communicatively coupled to the actuator of the rotatable member, wherein the controller is configured to perform actions including:
• rotating the rotatable member to be substantially aligned with a respective pair of opposing sidewalls of the build plate;
• linearly actuating the rotatable member such that the first and second coupling members engage the first and second sidewalls of the build plate;
• and
• rotating the rotatable member to move the build plate with the first and second coupling members engaged in the first and second sidewalls thereof.
