MITs SEAL 3D printing technique produces single injections that deliver multiples vaccines over time

Engineers at MIT have developed a 3D printing method that could allow doctors to deliver several drug or vaccine doses over a period of time with just a single injection. The "SEAL" technique works by 3D printing cup-like microparticles that can store and seal the drug doses.
