Comparative studies of the Knoop hardness of selected light-cured polymeric materials used for the production of spare parts working in kinematic nodes

摘要
Samples made of 4 types of com. polymer materials using DLP 3D printing technol. were post-processed in various conditions. A Phrozen Shuffle Lite printer and anycubic wash and cure finishing device were used to prepare the samples. Various rinsing methods were used to remove uncured resin particles, and the duration of addnl. UV exposure was also varied. The effect of the addnl. hardening time on the strength properties of the sample surfaces and the usefulness of the Knoop method in assessing the functional properties of the tested materials were demonstrated.
