Form 4 first.
Form 4L brings the groundbreaking technology of Form 4 to Formlabs' large format line of resin 3D printers, unlocking extreme speed, reliability, and print quality at any scale - from prototyping to production. With a build volume nearly 5x the size of Form 4, most parts in under six hours, and a more affordable accessory ecosystem, Form 4L enables our users to get more done than ever before.
