Laser technologies for fabricating individual implants and matrices for tissue engineering

Powder bed generation in integrated modelling of additive layer manufacturing of orthopaedic implants

“…Moreover, the ability of SLS to manufacture anatomically shaped scaffolds with designed microstructure made of bioactive and bioresorbable composite materials at high filler loadings allows for fabrication of scaffolds with a high degree of geometric complexity and enables the direct conversion of the digital representation of any object into its physical realisation. The method also enables the development of patient and tissue-specific reconstruction strategies [6][7][8][9].…”

A Short Review on Bio-compatible/Bio-degradable| Photopolymers for Stereolithography Bio-3D Printing

“…LS is a polymerization process in which the spatially controlled solidification of resin is achieved using various types of laser radiations. The key benefit of using LS are high spatial resolution ( ̴ 0.1 mm), fast manufacturing speed, high precision and a large variety of materials [3]. Commercially available LS 3D printers can print parts with an accuracy of 20µm.…”

Laser Sintering for the Fabrication of Tissue Engineering Scaffolds

“…To confront this problem and to be able to expand the range of materials that can be processed via laser sintering, surface selective laser sintering (SSLS) was introduced [8,10]. SSLS uses a diode laser with a wavelength of 0.97 µm, whose laser radiation is not absorbed by the polymer particles, which are therefore not heated.…”

“…They cause local melting, leaving most of the bulk particle cold. This technique allows the processing of thermally unstable polymers such as polylactides or polylactoglycolides and to obtain polymeric structures with bioactive proteins [8,10]. In the present case, ribonuclease was mixed to PLA, and carbon microparticles were added to absorb the laser radiation.…”
