This is an ongoing listing of terms that I have defined in order to get everyone to understand them and be on the same page when it comes to using these terms.

Be a chameleon- use the terminology that your audience uses.

2dLength and width only. Flat. Common 2d web images are photographs.
3dLength, width and depth/height. Common in computer graphics (CG) movies, engineering CAD designs and more.
3d printingThink of this as 2d printing over and over where the ink is something like a plastic.
3d bioprintingThe same concept as 3d printing but the filament is biological. No, they can’t yet 3d print a human heart. Yes, that is a goal.
ABSWhat Legos are made of. A plastic filament used in 3d printing that is more toxic when it is heated in order to print with it. So have your printer in a well-ventilated area. This plastic is less rigid than PLA so it is good when you want parts to connect.
ADLs or Activities of Daily LivingBasic everyday task like bathing, eating, dressing ourselves, walking (and there are more). When we lose these we might lose our independence and ability to manage our own care.
FilamentVarious material types used in 3d printers. The most common type is currently plastic.
GerontologyThe study of aging. This can be a negative position like medical issues that are associated with aging. Can be a positive framing like aging in place in order to stay at home as long as possible.
GerontechnologyTechnologies used by older adults.
Intellectual propertyThings that come from your head like copyrights, trademarks, and patents.
JPG or JPEGA file format that most digital raster files (most common of which is a web photo) are saved as. Well suited for many colors.
PLAA plastic filament used in 3d pribters that is made from corn. Non-toxic when it is heated up (so it is safe to have that 3d printer of yours inside). Material tends to be rigid and inflexible. Your model will melt if it gets too hot, so don’t leave your 3d-printed-with-PLA-filament-sunglasses on the dash of your car on a sunny day.
Raster imagesThese files are mainly photographs, comprised of either pixels is digital or dots on ink if printed. Think of these as graphics built using a Lite-Brite and you will understand the technical limitations to them. Some software used to create and manipulate raster images are Adobe Photoshop, Gimp. Always 2d (so they have width and height but no depth). The biggest drawback to these files is you have to worry about resolution with them. Remember when that Facebook photo printed blurry? It was a resolution problem. Technically we say that raster images are resolution dependent.
ResolutionA quantity measurement for raster images. Normally described in pixels per inch (ppi) for web/digital images and dots per inch (dpi) for printed images. Resolution settings are different depending upon where you are viewing your raster images. The concept to remember is that because of resolution, web photos are not friends with printed photos.
STLA popular file format for 3d models that will be 3d printed.
SVGA file format for 2d vector images. It’s a good one… open source, built with XML. So draw your shapes, lines, illustrations, and infographics in Illustrator and save your files as SVG. Many web browsers now natively support this file (so a viewer sees your design on your web page without having to install anything).

Graphic designers, if you use Illustrator to create your designs with the intention of 3d printing them, make absolutely sure your paths and shapes are closed and everything in your design is connected to something else.
Vector imagesIf you consider all graphic files, vector images are more numerous than raster images- blows them out of the water. These files are built by mathematical statements (versus pixels). They can be static or animated, 2d or 3d. One of the biggest plusses to vector images is that they are resolution independent. Simply stated, you don’t have to worry about blurry vector images no matter what size they are or where they are displayed. The most popular software for 2d vector images is Adobe Illustrator. With 3d vector files, the software playing field is much more crowded.
