Researchers have developed a new two-photon polymerization technique that uses two lasers to 3D print complex high-resolution structures. The advance could make this 3D printing process less expensive, helping it find wider use in a variety of applications.
"We combined a relatively low-cost laser emitting visible light with a femtosecond laser emitting infrared pulses to reduce the power requirement of the femtosecond laser," said research team leader Xianfan Xu from Purdue University."In this way, with a given femtosecond laser power, the printing throughput can be increased, leading to a lower cost for printing individual parts.
"In a conventional two-photon polymerization printing process, the femtosecond laser is first used to initiate a photochemical process that reduces the inhibition species in the material before printing starts," said Xu."We used a low-cost laser for this purpose instead." "This new printing approach could impact manufacturing technologies, influencing the development of devices across consumer electronics and healthcare sectors both now and in the future," said Xu. The researchers are now working to further improve the printing speed and reduce the cost of 3D printing.Researchers have developed a compact and lightweight single-photon airborne lidar system that can acquire high-resolution 3D images with a low-power laser.
