Smart laser Sintering: Deep Learning-Powered powder bed fusion 3D printing in precision medicine

International Journal of Pharmaceutics
Medicines remain ineffective for over 50% of patients due to conventional mass production methods with fixed drug dosages. Three-dimensional (3D) printing, specifically selective laser sintering (SLS), offers a potential solution to this challenge, allowing the manufacturing of small, personalized batches of medication.

Hybrid Data Fusion for Low-Cost High-Speed Monitoring in Powder Bed Fusion 3D Printing

2025 17th International Conference on Computer and Automation Engineering (ICCAE)
In laser powder bed fusion 3D printing, defects can be created in less than 100 µs, making it difficult and expensive to monitor and control the process in real time. Existing techniques either rely on the use of simple, high-speed sensors for control purposes (e.g., photodiodes) or high-resolution, low-speed sensors (e.g., cameras) to analyze print ...
