Abstract
Various applications in industry and medicine require the transmission of movement using systems that do not influence magnetic or electromagnetic fields. These components include systems which transmit linear or rotational motion, change position (switches), attach or detach to objects (latches), grip objects, etc. This paper looks into the possibility of producing such mechanisms using FDM 3D-printed parts from thermoplastic materials with embedded moving parts, which can be pneumatically actuated. In order to make the parts suitable for use in pressurized air systems, different sets of printing parameters have been investigated. PLA annealing is used in the attempt to minimize play and increase air-tightness of 3D-printed parts.

Various applications in industry and medicine require the transmission of movement using systems that do not influence magnetic or electromagnetic fields
One of the main aspects of automation is the control of moving parts. In certain applications, such as in medical research or medical investigation procedures, sensor testing, RF testing, fundamental physics research, etc., where movement needs to be transmitted close to equipment sensitive to magnetic and electromagnetic fields, the metal components predominantly used in the automation industry can interfere with critical process elements
There are experiments where the accurate determination of magnetic or electromagnetic fields and their interactions is required metal parts would interfere with these fields and represent additional error sources
Summary
Various applications in industry and medicine require the transmission of movement using systems that do not influence magnetic or electromagnetic fields. In order to make the parts suitable for use in pressurized air systems, different sets of printing parameters have been investigated [3, 4]. The inner walls of these parts should be fabricated using an increased material flow (over extrusion), or with an increased number of outside perimeters.
