Building Platform System for Additive Manufacturing

Building platform system for installation in an additive manufacturing device, comprising a building platform (2) serving as a component carrier, characterized in that

• the building platform system further comprises
• a plate-shaped machine interface unit (1) that is designed as a base for the building platform (2), which can be releasably fastened in a positionally fixed manner on the machine interface unit (1), and
• several base fastening units for the releasable fastening of the machine interface unit (1) in the additive manufacturing device,
• wherein
• each of the base fastening units for forming a screw connection with the additive manufacturing device comprises a connecting adapter (3) and a base screw (4) that is anchorable in a form-fitting manner in a screw head recess (3.1) provided laterally in the connecting adapter (3),
• each of the connecting adapters (3) is insertable as an anchor on the screw head of the base screw (4) in a rotation-preventing manner into an adapter recess (1.1) which is adapted to the shape of the connecting adapter (3) and open towards the building platform (2) of the machine interface unit (1),
• each of the connecting adapters (3) has a threaded bore (3.2) which is coaxially aligned with the base screw (4) anchored in the respective connecting adapter (3), wherein the threaded bore (3.2) on the connection adapter (3) is located on the side of the screw head opposite the thread of the base screw (4),
• the machine interface unit (1) has a zero-point clamping system (6) for the releasable fastening of the building platform (2) to the machine interface unit (1), and
• the machine interface unit (1) has, on its side facing the building platform (2), several fitting bores (9) for the insertion of dowel pins (8).
