= Different types of small-scale manufacturing machines such as 3D printers, laser cutters, and programmable sewing machines, combined with an electronic design blueprint, enable people to create a wide range of objects. [1]

Description

Example

"A leading example of the power of personal-scale manufacturing technologies is Mark Kendrick. Kendrick designs beautiful custom model train parts. His designs are captured in software blueprints and sold online. Rather than selling his unique model train part designs to large toy companies that would mass produce them, instead, Kendrick targets hobbyist model train enthusiasts that own, or have access to their own small-scale manufacturing machine. Since the cost of manufacturing a custom train part on a small-scale 3D printer is only $25, Kendrick’s niche market of loyal consumers can afford to manufacture their own train parts -- no investment in factory-scale production is needed. Imagine if a model train enthusiast purchased Kendrick’s electronic blueprint and tried to produce the stainless steel train cowcatcher (shown in the figure) in a factory. The high cost of setting up a factory infrastructure would be well out of the reach of the average consumer. Unless a commercial toymaker was confident Kendrick’s custom designs would sell in large numbers, she would probably not invest in the set up costs; the market for custom cowcatchers is too small to warrant the costs of setting up large scale production. Personal-scale manufacturing tools are automated artisans: they combine the power of computer-guided manufacturing machines with the skilled artisan’s ability to create custom objects for niche markets. Unlike artisan or large-scale factory production, however, personal manufacturing is a low cost process that doesn’t require investment in an assembly line, or a skilled artisan."

Tools

"Personal-scale manufacturing tools enable people that have no special training in woodworking, metalsmithing, or embroidery to manufacture their own complex, one-of-a-kind artisan-style objects."

Typology of Personal Manufacturing Machines (Hardware)

Desktop 3D Printers

Hod Lipson and Melba Kurman:

"3D printers use as an additive process, meaning they make objects by systematically depositing a chosen raw material in layers. Somewhat similar in concept to that of an inkjet printer that orchestrates different colored print cartridges to form an image onto paper, the most common household 3D printing process involves a “print head” that works with any material that can be extruded, or squirted through a nozzle. Another common type of 3D printer uses a laser beam or glue to selectively fuse powdered plastic, metal, or ceramic raw material in layers." (http://web.mae.cornell.edu/lipson/FactoryAtHome.pdf)

Desktop CNC Routing and Milling Machines

Hod Lipson and Melba Kurman:

"more established than 3D printers are desktop-sized numerically controlled (CNC) routing and milling machines. These machines use a physical blade to cut and carve precise designs into a broad range of materials. Under the guidance of an electronic design blueprint, a rotating mill bit, sometimes called a cutter, is spun along by a motor called a router or spindle. As the electronic blueprint guides the cutter along x, y and z coordinates, the cutting tool makes multiple passes over the material to create perfectly carved engravings or shapes."

Desktop Laser Cutters and Engravers

Hod Lipson and Melba Kurman:

"laser cutters and engravers use intense, focused beams of light to cut out shapes and engrave images onto a wide variety of materials. Laser machines can produce images, text or designs in an amazing level of detail and precision. Laser cutters are versatile and can cut a range of materials from wood to plastics to leather, and can etch or engrave metals, glass and ceramics. Their versatility, speed and precision make them ideal machines for small businesses to create design prototypes and customized consumer products. Beyond engraving, one of the most common uses of home-scale laser cutters is to precisely cut parts out of a sheet of acrylic or wood. These parts can be assembled by hand into complex, 3D products."

Desktop Sewing and Embroidering Machines

Hod Lipson and Melba Kurman:

"Automated, personal-scale embroidery machines are already available in mainstream stores such as JoAnn Fabrics." (http://web.mae.cornell.edu/lipson/FactoryAtHome.pdf)

Desktop Circuit Makers

Hod Lipson and Melba Kurman:

"PERSONAL CIRCUIT MAKERS FABRICATE MULTILAYER PRINTED CIRCUIT BOARDS ON YOUR DESKTOP, WITHOUT THE TRADITIONAL CHEMICAL-INTENSIVE INDUSTRIAL PROCESSES, EITHER BY MILLING OR SPRAYING CONDUCTIVE TRACES.

at-home manufacture of circuit boards is a rapidly emerging application for hobbyists and electronic designers.

Desktop circuit makers offer a clean alternative to traditional chemical-based processes, making them an appropriate tool for the classroom, lab or home." (http://web.mae.cornell.edu/lipson/FactoryAtHome.pdf)

Computer-Aided Design Software

Hod Lipson and Melba Kurman:

1.

"Hardware is not useful without software. The adoption of personal-scale manufacturing machines comes hand-in-hand with the emergence of cheaper, and increasingly accessible computer aided design software (CAD).

Industrial designers and engineers have used CAD software for decades. However, CAD software has been slow to reach the consumer market and remains one of the last bastions of software still targeted to, and controlled primarily by high-end industrial users. CAD software is expensive, requires a computer with an excellent monitor and lots of memory, and perhaps most importantly, has a long learning curve that deters casual users. In industry, CAD software long ago replaced drafting tables and paper blueprints. However, due to its cost and complexity, CAD software has remained the tool of trained specialists and professional designers, not home users.

Industrial designers use CAD software mainly to design detailed 3D models or 2D drawings of components or floor plans. Process diagrams are another popular application.

The cost of CAD software is dropping and software companies are working hard to make it more user-friendly. In 2008, Google entered the CAD game with a no-cost version of 3D modeling software called SketchUp. Currently, SketchUp is offered in a “Pro” version that costs about $500 (at the time of this writing), alongside a free version."

"Realistically, though CAD software continues to drop in price and complexity, it’s still nowhere near as user-friendly as today’s mainstream office applications.

Another barrier is that even the low-end CAD software described above was not created with personal fabrication applications in mind. Instead, today’s CAD software reflects its industrial legacy and is intended primarily for modeling and visualization applications rather than designing consumer goods and machine parts.

Ideally, to accelerate the adoption of CAD software aimed at the personal manufacturing market, design software would need to be easier to use and optimized for the unique constraints and capabilities of the physical manufacturing process." (http://web.mae.cornell.edu/lipson/FactoryAtHome.pdf)

"Personal manufacturing is where personal computing was in the 1970s, before the advent of home-scale computers and consumer software. Recent rapid technological advances in personal manufacturing technology, combined with shrinking costs of machines, increasingly available design software and raw manufacturing materials, plus most peoples’ tendency to conduct more daily activities online, are tipping personal fabrication from the realm of hobbyists and pioneers to the mainstream."
