Lab lets public use 3-D printing and laser tools

Laser engraving and cutting may release toxic
fumes that can affect people's health, studies show.
On any given day, an unusual cross-section of artists and entrepreneurs might be found tooling away on the cutting and industrial printing machines at a Central Square lab in Cambridge: a maker of percussion instruments, a fashion designer, even the owner of an electronic cigarette retailer.

The lab is called Danger!Awesome, and it is helping to introduce 3-D printing and laser-cutting technologies to people who don’t have the knowledge or access to factory- grade equipment to turn their big ideas into products.

The lab also performs professional-grade jobs for corporate clients, including the nearby Google Inc. offices. But to get 3-D printing to become an everyday technology adopted by the masses, cofounder Ali Mohammad said Danger!Awesome’s main calling is to teach hobbyists and entrepreneurs the technology isn’t all that difficult to master.

“Even if you don’t think you can make something, we will hold your hand through the entire process,” Mohammad said.

Like other labs, Danger!Awesome has both 3-D printers and laser cutters.

The former create solid objects by slowing extruding layers of plastic or other materials, based on a pattern designed in a computer program.

The latter starts with a block of material and meticulously burns away everything except the desired shape.

“You get this satisfaction from creating things,” Mohammad said. “There is something deeply, primally satisfying about building something you can touch.”

The company is among a number of startups in the Boston area anticipating that people will pay for training and access to bleeding-edge fabrication technologies.

In Somerville, Astisan’s Asylum trains members to use a Stratasys uPrint. The Printing Bay in Waltham offers classes and access to a MakerGear M2.

And on Newbury Street in the Back Bay, the 3-D printer manufacturer MakerBot has opened a store where the public can watch demonstrations of 3-D printing, scan and print their own designs, and buy a machine for their own use.

In Burlington, Einstein’s Workshop offers science and engineering classes aimed at children — including courses in 3-D printing and laser cutting for kids as young as second-graders.

“When you give kids access to these machines, it’s amazing what projects they think of themselves,” said workshop founder Henry Houh, who took a laser-cutting class at Danger!Awesome.

Visual artist Lannie Hathaway got so hooked on the new technology that she now works at Danger!Awesome, where she continues to use the machines for her own engraving and illustration projects.

“Using the tools that are used for engineering to make my own work come to life was very exciting,” Hathaway said.

The 3-D groundswell is being embraced by academia, as well.

Northeastern University, for instance, opened a comprehensive 3-D printing, 3-D scanning, and laser-cutting lab as part of its library system last year, and is developing coursework around it.

And the Massachusetts Institute of Technology supports a global network of 3-D printing laboratories through the Fab Foundation,a nonprofit started by the school’s Center for Bits and Atoms.

Mohammad was a doctoral student at MIT in computational linguistics when he stumbled on the technology, sneaking into the labs with laser cutters late at night to try out the equipment.

He became friends with Nadeem Mazen, and they decided to start a business. Their lab does about 50 orders a week, more around the holidays.

Laser engraving and cutting machines can pose a health risk

Laser engraving and cutting can
produce harmful fumes and dust.
People may not need engraved mementos all the time – but when they want to mark special occasions, a laser engraving and cutting machine can help create the right product.

Laser engraving and cutting machines are often the heart of small businesses that rely on creativity and the ability to engrave memories into keepsake items.

Most of these customized engravings are done in the store, and many engravers use computers connected to engraving machines and 3D designs to stand out among others.

Many businesses also combine laser engraving and cutting services with other services such as design, business branding and marketing as well as product design.

In industrial settings, laser engraving is also often used to mark certain products and materials.

What are the health risks of laser engraving and cutting?

Laser engravers and cutters work with wood, glass or other hard surfaces to engrave logos, messages of personal interest and for special occasions such as wedding or anniversary presents. They also make glass and acrylic awards for companies and sporting organizations.

The laser cutting machines should ideally produce smooth edges that don’t require polishing, they should work quietly and produce no dust, and they should have a fast processing speed, high precision, less waste and high efficiency.

Unfortunately, even large laser cutting machine manufacturers acknowledge that the dust and fumes produced in the engraving process can pose a health hazard.

That is why many machines come with a blower, vacuum, fan or other device to pull dust and fumes from the work area of the laser machine. Not only can the dust damage the equipment itself and destroy the optics, the fumes can be irritating and unhealthy.

How do air cleaners help?

By connecting a portable air cleaner with activated carbon and HEPA to the laser cutting machine, operators can remove chemical vapors, laser cutting fumes and fine particles while preventing the constant clogging that plagues other air cleaning systems.

Electrocorp has developed highly effective source capture air cleaners for laser engraving and cutting, to remove airborne pollutants before they become airborne and circulate.

This capture method offers superior protection for laser cutters and engravers, prevents product contamination and safeguards sensitive laser optics on the machine.
