AI Technical Summary

Technical Problem

Existing build platform systems for additive manufacturing require high setup effort and are not flexible for use across different devices, making them inefficient and costly, especially in hybrid manufacturing scenarios.

Method used

A build platform system with a detachable machine interface unit and base mounting units, featuring a zero-point clamping system, dowel pins, and adaptable connectors, allowing precise positioning and calibration once per device, enabling flexible installation across various additive manufacturing devices.

Benefits of technology

Facilitates precise and repeatable positioning of components with reduced setup effort, enhancing manufacturing accuracy and cost-effectiveness in hybrid and new part production, as well as component repair, by minimizing the need for repeated calibration.

Abstract

Build platform system for installation in an additive manufacturing device, comprising a build platform serving as a component carrier (2), wherein the build platform system further - a plate-shaped machine interface unit (1) which is designed as a base for the build platform (2) which can be detachably fixed to it in a fixed position, as well as - has several base mounting units for detachably mounting the machine interface unit (1) in the additive manufacturing device, characterized in that - 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 can be positively anchored in a laterally provided screw head recess (3.1) of the connecting adapter (3), - each of the connecting adapters (3) can be inserted as an anchor on the screw head of the base screw (4) in a rotationally secure manner into an adapter recess (1.1) of the machine interface unit (1) that is form-fitting to the connecting adapter (3) and open towards the build platform (2), - each of the connecting adapters (3) has a threaded bore (3.2) arranged coaxially with the base screw (4) anchored in the respective connecting adapter (3) on the side of the screw head of the base screw (4) opposite the thread of the base screw (4), - the machine interface unit (1) has, in addition to the base mounting units, a zero-point clamping system (6) for attaching the build platform (2) to the machine interface unit (1), and - the machine interface unit (1) has several locating bores (9) on its side facing the build platform (2) for receiving locating pins (8), wherein the build platform (2) - either a standard building platform (2.2) which can be detachably fixed in position by means of building platform screws (5) in the threaded holes (3.2) of the anchored connecting adapters (3), - or a quick-change build platform (2.1) which can be fixed in position but detachably attached to the machine interface unit (1) by means of the zero-point clamping system (6).
