About This Quiz

Regular printers are pretty handy, but their up-and-coming cousins, 3-D printers, add a whole new dimension to the printing process. Literally! How much do you know about the fascinating field of 3-D printing? Take this quiz and find out!

1.0 of 20

CNC machining is a subtractive process. The other answers listed are additive manufacturing (AM) processes referred to as 3-D printing.

Who owns the trademarked 3-D printing procedure actually called 3-D Printing (3DP)?

MIT licenses 3-D printer manufacturers to use 3DP technology, a binder 3-D printing approach. To obtain a license, a manufacturer must demonstrate the use of a unique combination of materials in the 3DP process.

What's the term used to describe 3-D printing when it's used to create models for testing a product's design?

Rapid prototyping (RP) has been a major player in the development of 3-D printing.

What was the name of the first commercially successful 3-D printer using the inkjet approach for rapid prototyping (RP)?

The ModelMaker by Solidscape came out in 1994.

Which of the following fields or industries have used 3-D printing?

The variety of applications for 3-D printing continues to grow, from automobiles to artwork, fabrics to furniture, and jet planes to jewelry.

6.0 of 20
Which of the following 3-D printing approaches involves melting the material, then allowing it to cool and solidify to form each new layer?

In a sintering approach to 3-D printing, each new printed layer is formed by melting a powder. These particles fuse together and form a specific shape. Each new layer adheres to the previous.

In what year was 3-D printing industry leader 3D Systems founded?

Since its 1986 founding, 3D Systems, based in Rock Hill, S.C., has created several products using different 3-D printing approaches. Some of its trademarked 3-D printing innovations are now used throughout the industry.

Which of the following 3-D printing approaches uses a liquid glue added to a fine powder?

The binder is in liquid form, and it's applied to the fine powder to create each new layer.

9.0 of 20
Which of the following 3-D printing approaches applies an ultraviolet light to a liquid polymer to change it into solid plastic?

Photopolymerization uses an ultraviolet laser and a perforated platform that moves through the liquid polymer during the printing process.

10.0 of 20
Which of the following 3-D printing approaches uses inkjet technology to apply a liquid that quickly solidifies to form each new layer?

Direct 3-D printing applies a liquid form of a wax or plastic polymer to form each new layer of the solid shape it's printing.

Which of the following materials have been used to create objects with 3-D printers?

This is an easy one. Scientists and inventors are continually experimenting with different materials for use in 3-D printing.

12.0 of 20
Which of the following 3-D printer models is priced under $10,000 and is small and light enough to fit on a desktop?

Many Solidscape printers are small enough for your desktop, and the uPrint by Stratasys is one of the more affordable desktop-sized 3-D printers. However, the V-Flash is the only model listed that's priced under $10,000.

Since the nozzles dispensing the binder don't have to provide all the materials used in the final object, they can be smaller and can work faster than they would in direct 3-D printing.

What are the names of two companies that provide 3-D printing services for the average person who doesn't want to buy the equipment?

Shapeways and Ponoko each let you send in your own 3-D designs for printing. They also give you the option to set up an online store, allowing you to make money when other shoppers order prints of your design.

15.0 of 20
Before you print out something on a 3-D printer, which file format should you convert your file to?

The STL file format was developed by 3D Systems in 1987 and is the most widely accepted file format for 3-D printers. STL stands for "standard tessellation language."

16.0 of 20
One 3-D printing process has the trademark name of SLS. What does SLS stand for?

Selective laser sintering (SLS) is a form of 3-D printing that uses a laser to melt flame-retardant plastic powder, which then solidifies to form a printed layer.

17.0 of 20
What type of software can you use to design a 3-D object that you want to print?

Computer-aided design (CAD) and computer-aided manufacturing (CAM) are technologies that incorporate the power of computers in manufacturing for a wide variety of parts and products. 3-D printers are designed to work from files produced by CAD software.

What's the official term from ASTM International describing manufacturing technology that creates an object by adding material on a layer-by-layer basis?

ASTM International, formerly the American Society for Testing and Materials, has been working to create standards for what it officially calls additive manufacturing (AM), an area that includes (and is often referred to as) 3-D printing.

What sort of material did physicist and maker Windell Oskay use in his home-built 3-D printer?

In 2007, Windell Oskay wrote a series of blog posts on his Web site, EvilMadScientist.com, chronicling his adventures building the CandyFab, a 3-D printer which used sugar as the printing material. Pretty sweet, huh?

20.0 of 20
Which of the following is the opposite manufacturing approach to additive manufacturing (AM)?

Computer numerical controlled (CNC) machining is a subtractive, rather than an additive, process, kind of like carving a statue from stone. CNC machines remove material from a block until the material that's left is in the shape you wanted.
