日 時 : 2015年 10月 26日(月) 10:30〜11:30
場 所 : 北海道大学工学部A棟1階 大会議室 A1-17 (札幌市北区北13条西8丁目)
講 演 : 「3D
Printing of Micro Objects by Two Photon Polymerization Method」
Prof. Tien-Tung

Professor, Department of Mechanical Engineering, National Taiwan University,
Taiwan)
Two Photon Polymerization (TPP) is a powerful technology that can be used for three-dimensional (3D) printing of complex functional micro objects.
It is a laser-based prototyping technique with full 3D capability
and sub-micron resolution.
We study the development of design and fabrication processes based
on 532 nanometer Q-switched Nd:YAG green lasers and commercial materials
Polymer 3015 and ORMOCOMP. Micro lasers with sub-nanosecond pulses
of visible light are efficient and low cost for two-photon micro fabrication.
Polymerization is easily obtained with milliwatt average powers (12 kHz
repetition rate).
A computer aided manufacturing (CAM) software has been developed
to design several micro objet 3D models in AutoCAD, calculate their laser
trajectories,
and drive the laser to polymerize polymer resins. It is an open
platform for design of 3D solids with full access to entities information,
and an efficient slicing command that can cut solids from any
orientation plane. Micro objects, such as name cards, gratings, springs,
gears, spherical lenses,
Fresnel zone plate lenses, and valves, have been successfully
manufactured with good quality.
