A new, less expensive 3D printing method uses two lasers for two-photon polymerization to increase practicality for consumer electronics, biomedical applications and more. To reduce the power requirement of the femtosecond laser used in 3D printing, the Purdue University team combined a relatively low-cost laser emitting visible light with a femtosecond laser emitting infrared pulses. Now, the team is working to improve the printing speed and reduce the cost of 3D printing. Read more in our Newsroom, link bio* #3Dprinting #lasers #laserscience #3D #technology
