Fabrication of dimensionally accurate 3D micro components by projection micro-stereolithography technique

Development and Characterization of PEGDA Microneedles for Localized Drug Delivery of Gemcitabine to Treat Inflammatory Breast Cancer

“…The entire fabrication process was carried out using the PµSL system exclusively developed at CMTI and is currently branded as SUKSHM 3D ® with a tag-line ‘micro rapid prototyping’ [ 28 ]. Primarily, the optical system comprises of UV LED as the light source emitting light in the range of 340 nm to 410 nm, and a peak intensity wavelength of 385 nm.…”

“…Post-development of CAD files they are converted into STL files which were further sliced into series of cross-sections of desired thickness by the control unit. Thereafter, the image files are supplied as input to the PµSL system (SUKSHM 3D ® ) [ 28 ] and was controlled using LabVIEW software NXG 5.0.…”

“…The entire photo-polymerization reaction can be controlled by varying various process parameters such as intensity of light, concentration of the photo-initiator or monomer and lastly the exposure time. The entire fabrication process was carried out using the PµSL system exclusively developed at CMTI and is currently branded as SUKSHM 3D ® with a tag-line 'micro rapid prototyping' [28]. Primarily, the optical system comprises of UV LED as the light source emitting light in the range of 340 nm to 410 nm, and a peak intensity wavelength of 385 nm.…”

“…The MNPs of polyethylene glycol diacrylate (PEGDA) were fabricated by a relatively novel three dimensional (3D) micro-fabrication technology called Projection Micro-Stereo Lithography (PµSL) method. More particularly, the study is aimed at developing blank MNs with accurate dimensions by employing proprietary PµSL system, SUKSHM 3D ® , developed at CMTI [ 28 ]. Initially, PEGDA is cross-inked with diphenyl (2,4,6-trimethyl benzoyl)-phosphine oxide (TPO) to form a 3D polymer network.…”
