SUMMARY AND CONCLUSION

The presented system for AR assisted part removal in 3D printing provides new way of helping technicians in sensitive operation of printed part extraction. The risk of damaging printed parts in the process of removal from loose powder is greatly reduced through use of such a system, especially with use of head-mounted AR which enables technician to keep visualized build layout constantly in field of view, while the use of mobile AR device provides periodical checks of layout. The best results can be achieved when building layouts that are relatively complex or when printing delicate parts.

Further work on this system will be directed mostly to visualization manipulation, since visualizing of complex builds in some cases proves to be distractive to the operating technician. The tools for manipulation of AR visualization that will be developed are cutting plane and object visibility. The technician will be able to hide objects through selection of visible objects or by means of moveable cutting plane. By hiding already extracted parts, AR visualization may provide better compliance with progress of removal operation, while cutting plane also resembles the process of removing loose powder from top to bottom of the build chamber.

The application of system for augmented reality assisted part removal, in presented state and with further improvements, will improve productivity and lessen the manufacturing costs in powder-based 3D printing services.
