Personal 3D Printers

The additive manufacturing (AM) industry is experiencing staggering growth in low-cost “personal” 3D printers. These are products that typically sell for about $1,000 to $2,000 and are available as a kit or assembled machine. The majority originated from the RepRap open-source machine development at Bath University in the UK. RepRap is based on fused deposition modeling (FDM) technology developed and commercialized by Stratasys in the early 1990s.

Professional-grade, industrial additive manufacturing systems are those that are established in industry and sell for more than $5,000. Sales of these systems grew by an estimated 5.4% (CAGR) to 6,494 units in 2011, excluding personal systems. This compares to an estimated 6,164 systems sold in 2010 (also excluding personal systems), which resulted in impressive growth of 37.4%.

Personal 3D printer unit sales grew 289% in 2011, with an astonishing 23,265 units believed to have been placed, as shown at However, personal 3D printers represent just $26.1 million of the total market for AM systems sales in 2011. If the personal systems category continues to grow at its current pace, it will quickly become an interesting market segment for system developers and investors.

Wohlers Talk: Why Most Adults Will Never Use a 3D Printer

Many have speculated on whether everyday consumers will purchase and use a 3D printer. With prices dipping to $350 for a kit and $550 for an assembled system, they are certainly affordable. Some believe that a 3D printer will someday be in every home and used to produce replacement parts as household products break or wear out.

As shown by Shapeways, Materialise, FutureFactories, Ponoko, and others, consumers are definitely interested in products made by additive manufacturing and 3D printing. Shapeways claims to be producing more than 90,000 parts (about 25,000 products) per month by AM, with a high percentage going to consumers. For years, Materialise’s .MGX division has offered striking lighting designs, sculptures, and other products, with consumers paying hundreds of euros for one of them.

Indeed, consumers have an appetite for products made by additive manufacturing. However, most consumers will never own or operate a machine to produce these products. Instead, they will go to Shapeways, Amazon, or to another service or storefront to purchase these products. Most will not know, or even care, how the products were made—no different from the way they now purchase products. Consumers only care about receiving good value.

Someday, a company will offer a very low-cost, easy-to-use, and safe 3D printer targeted at children. This market opportunity, I believe, is very big because children like to imagine, create, touch things, play, and entertain themselves. These kids will be producing vehicles, action figures, puzzles, and just about everything imaginable. They are our future designers, engineers, and manufacturing professionals.

Most parents and adults are not candidates for a 3D printer. They do not want to mess with the data, manufacturing process, clean-up, and finishing of parts and products. Even if they owned or had access to a machine, it would probably not be capable of producing parts in the right material with the mechanical properties, color, surface finish, and texture needed for the part(s) they are trying to create or replace. These types of parts will continue to be produced by industry professionals and that’s why most adults will never use a 3D printer.
