3D printing has revolutionized the way we think about manufacturing and design. But when did 3D printers get patented? To understand the significance of this technology, we must delve into its history and key milestones that have shaped its evolution.

Early Beginnings: The First Patents

The journey of 3D printing began in the 1980s. In 1986, Charles W. Hull invented the first 3D printer, known as stereolithography (SLA). He was awarded a patent for this groundbreaking technology in 1986, marking a pivotal moment in the history of 3D printing patents. Hull's invention allowed for the creation of three-dimensional objects from digital files, laying the foundation for future developments.

Key Milestones in 3D Printing Patents

• 1986: Charles Hull patents stereolithography.
• 1991: Scott Crump patents fused deposition modeling (FDM), a process that uses thermoplastic materials.
• 1999: The first 3D printer using selective laser sintering (SLS) is patented.
• 2005: The first patent for a 3D printer that can print with multiple materials is filed.

These patents not only highlight the technological advancements in 3D printing but also illustrate the growing interest and investment in this field. As the years progressed, more patents emerged, each contributing to the refinement and expansion of 3D printing capabilities.
