Layer-to-layer closed-loop switched heating and cooling control of the laser powder bed fusion process

Key Points

• Layer-to-layer closed-loop control significantly enhances temperature management during the laser powder bed fusion process.
• The system achieved a more consistent temperature range of 100-300 degrees Celsius during heating and cooling phases.
• Closed-loop switched heating and cooling control was used to optimize thermal conditions within the laser powder bed.
• Improved stabilization of the process may lead to enhanced material properties in final products.
