Integrating 3D Printed Grinding Tools and Closed‐Loop Temperature Management for Optimal Surgical Outcomes Open
Grinding is a commonly employed surgical technique for the partial removal of bone. However, the grinding process often generates excessive heat at the interface, leading to localized temperature raise. This can result in irreversible dama…
Design of 3D printed metal frame nested porous polyimide composites Open
Porous polyimide (PPI) can store oil, but the mechanical properties are also weakened by the pores. To solve this problem, a 3D printed metal frame-PPI nested composite (MFP) was proposed. The composite material has a binary pore structure…
Enhancing the 3D printing fidelity of vat photopolymerization with machine learning-driven boundary prediction Open
Like many pixel-based additive manufacturing (AM) techniques, digital light processing (DLP) based vat photopolymerization faces the challenge that the square pixel based processing strategy can lead to zigzag edges especially when feature…
