Origins of 3D Printing: The First Steps

The Conceptual Beginnings

The conceptual seeds of 3D printing were planted in the 1980s, with the vision of constructing objects layer by layer, adding material rather than carving it away. This idea marked a significant departure from traditional manufacturing methods, which predominantly relied on subtractive processes like machining and milling.

The first steps toward making this vision a reality involved the development of techniques that could interpret digital designs into physical objects. Early innovators focused on methods such as stereolithography (SL), which used ultraviolet light to harden liquid resin into solid shapes. The potential for this technology to revolutionize manufacturing was clear, but the journey from concept to reality was fraught with challenges.
