This allows the liquid to be moved without direct contact between the fluid and the mechanical components of the pump.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The pump body was designed as a compact 3D printed assembly, with a focus on clean mechanical integration, simple assembly and controlled tube compression. The rotor geometry, bearing position and pump track were developed around the selected silicone tubing to achieve a functional pumping mechanism in a small form factor.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This prototype is part of RoghenLab\u2019s work on functional mechanical systems, fluid-handling concepts and compact electromechanical assemblies.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Technical Details<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Stepper-driven rotor<\/li>\n\n\n\n<li>Three-roller compression system<\/li>\n\n\n\n<li>Silicone tube: 6 mm OD \/ 4 mm ID<\/li>\n\n\n\n<li>3D printed pump body<\/li>\n\n\n\n<li>Circular pump track<\/li>\n\n\n\n<li>Bearing-based roller system<\/li>\n\n\n\n<li>Compact square body layout<\/li>\n\n\n\n<li>Designed for electronic speed control integration<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Development Focus<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The design focuses on the relationship between tube compression, roller position and pump track geometry.
