| Résumé : |
When printing high-performance polymers such as PEEK, stresses occur in the component due to the relatively high printing temperature and the changes in the material structure. These stresses can lead to microcracking, warping, cracking and ultimately to component failure. In the Smart Printbed project, a system was developed to minimize these influences and also save electrical energy. |
| Note de contenu : |
- The zone heating system supplies energy only where it is needed
- Design of the smart print bed
- Optimal thermal management requires perfect interaction
- Fig. 1 : The smart printbed can heat, cool and measure temperature. The schematic sketch of the print bed shows the structure, which consists of 25 individual Peltier elements
- Fig. 2 : It all depends on the correct wiring : Only with a bridge circuit can the Peltier elements assume all three operating states (heating, cooling and measuring) |
