Expiration of patents facilitates spread of 3D printing
Around 2010 the expiration of major patents caused the first Additive Manufacturing hype. Especially the expired patent for Filament Material Extrusion, better known as FDM, caused a wave of new startups that specialized in low-cost desktop printers that made 3D printing widely accessible even for private use. MAKERBOT, ULTIMAKER and PRUSA are only some companies, that focused on this market segment. Media and politics were praising the technologies as the next revolution in manufacturing. Reality during the 2000´s, however, was still a little bit different. Many systems lacked reliability and high productivity, so that series production was not in the focus.
Since then, many suppliers have developed systems that meet industrial requirements regarding reliability and productivity. Besides the established machine OEMs like 3DSYSTEMS, STRATASYS and EOS new players emerged and were able to collect large funding for a fast machine development and growth. One example is CARBON which was founded in 2013 and collected over EUR 550 million in until 2019. Even if Additive Manufacturing was not able to revolutionize the market in the beginnings of the 2010´s the hype caused the intensification of activities and increasing adoption of the industry. In 2016 HEWLETT & PACKARD stepped into the Additive Manufacturing market. With the introduction of its MJF technology it increased the pressure on the well-established SLS systems supplier to further innovate, to not lose to much of their market share.
With regards to the polymer market more and more series production applications are realized by Additive Manufacturing. Especially the consumer market with its mass customization applications seems fit for AM. Just to name a few examples, today AM is already used to produce molds in high quantity for the production of aligner in the dental industry. It is also used to customize frames for glasses and hearing aids. Another great example of the customization of the process is the production of prosthetics which increase the comfort of wearing.
In 2020 and the beginning of 2021 major acquisitions took place in the polymer AM market. STRATASYS acquired ORIGIN and RPS to diversify their technology portfolio. And ENVISIONTEC was acquired by DESKTOP METAL to add Area-wise Vat Polymerization, a high volume polymer AM production technology to their machine offerings. Additionally, system suppliers like MASSIVIT and MARKFORGED have announced to go public, to further intensify the development of their technologies and increase market penetration.
