In the 3D printing process, a highly focused laser beam scans rapidly across a bed of metallic powder to melt it but tends to leave behind pores that weaken the material. Now scientists using the Advanced Photon Source have identified new pore formation mechanisms and shown that applying the right magnetic force can significantly reduce the problem.
