IT’S A NEW FRONTIER
3D Printing is still relatively young. The ideas for it came in the ‘80’s, but the ideas for it weren’t really put to use until the ‘90’s and it wasn’t until recent years that the prices for 3D printer have come down to a level that home users can start affording them. As a result, everyday there are more and more 3D printers in the homes and in small businesses and the number of people using 3D printers is growing all every day. But the whole 3D printing industry is so young and new, there are still many areas and parts left to define. As an example, what do you call a person who uses a 3D printer? You can’t call them a “3D Printer”, that’s already taken. The term “3D Printer User” or “Someone who 3D prints” just seem to be too cumbersome and long to say. What if we use a different spelling: “3D Printor”, with an ‘o’ instead of the ‘e’, for someone who 3D prints? Nah! On paper, that would work, but it would be hard to tell the difference in spoken conversation. I’ve searched and searched other people’s term for someone who 3D prints and I’ve ran across almost nothing out there. I did once hear someone use “Digital Maker”. It’s something, but it doesn’t quite nail it down. A person who uses a 3D printer certainly is making in the digital arena, but so is a person using a CNC machine, plasma cutter or even a digital photographer, for that matter. But “Digital Maker” is better than anything I’ve come up with. Maybe you’ve got an idea for what we can call a person who uses a 3D printer. If so, now’s your chance to grab a spot in history. You can be the first to coin the phrase for all of posterity. If you have any ideas, leave them in the comment section below and if you come up with something good enough, our readers may discover it and start using it. If it’s really good, I don’t see how anyone could help but use it.
There are a lot of unknown terms in the developing 3D printing world that haven’t yet been discovered or even clearly defined. There are many functions, actions and objects that haven’t been labelled yet. Heck, there are a lot words, phrases and acronyms that are so new or have new 3D printing meanings added to them that their definitions are still being worked out and refined. Some people may think of the terms as one thing, while others may think of them very differently and still yet, some people are unfamiliar with them completely and not just because they are newbies to 3D printings.
WE NEED A GOOD GLOSSARY SOURCE
What we need is a good glossary. What we need is a really good, reliable source of definitions that is kept up-to-date. It was my original intention for this website to NOT create any content, other than my blogs, I would just LINK to the best stuff about 3D printing I could find on the internet. But, in the case of a truly good glossary, I couldn’t find any that was worth pointing to. Oh, there are plenty of 3D printing glossaries out there, but they’re either incomplete, not kept up-to-date or just poorly made . That is, at least of the first few hundred or so I looked at. Okay, that might be a slight exaggeration, but I did find and read a lot of glossaries. So, I think we are going to have to come up a glossary ourselves and go ahead post it here on this website. I’ll try to get it started as best I can, but I’m hoping I can count on some help from my readers, correcting me where I get a definition wrong or when a definition has changed and/or introduce me and the rest of us to new terms as they are developed.

A technology that uses laser to partially cut (or burn) away material in order to engrave an object.
Level (Or Leveling The Bed)
This is a misnomer. It is not the actual paralleling of the build surface to the local horizon or to the ground or work surface on which the printer is sitting on, but if done correctly is the calibration setting of the build surface to be parallel to the ‘X’ axis of the 3D printer and parallel to the travel path of the ‘Y’ axis. (See also: Tramming)

(A side note: Sometimes molds are made from a single part/block. If so, the mold material has to be torn away and is usually used once or if the mold is a single part/block, it is a two-dimensional form with depth and is used “open-faced”; think: the way an ice tray is used.)
Movement refers to when the printhead moves from one part of the print to another while it is NOT extruding plastic and the speed is how fast is it moving during that time. Otherwise, when it is moving and extruding plastic it is known as ‘print speed’.
The part of the hot end of a 3D printer where the molten thermoplastic is deposited onto the print. Usually labelled by the size of the aperture in terms on millimeters.

Any part of 3D object during the printing process which is not directly supported underneath by other parts of the same or different object. Note: If consecutive layers use a partial self-support and the angle of this self-support is greater than 45 degrees, support structure will usually be needed.

A generic name for processes which use light to solidify photopolymers, such as used in stereolithography.

When the printhead stops emitting plastic during a move to another area of the item being printed, the FDM will retract the filament a set amount and speed to prevent unneeded plastic from oozing from the nozzle causing the undesired condition of stringiness.
Seen as a minor problem, it is a pattern on the surface of 3D printed objects, usually along their ‘X’ and ‘Y’ axis’, that resembles the look of salmon muscle tissue. Most new 3D printers have eliminated this pattern from their prints, but for older printers and newer ones that still have the problem, it can be fixed with the edition of devices that adds a special arrangement of diodes into the control wires of the stepper motors, called smoothers.
Selective Laser Sintering (SLS)
A 3d printing technology which uses a laser and heat to melt a powdered material, usually a metal, one layer at a time.

An additional ring/loop of build material laid down flat, outside and equidistant from the perimeter of the first layer of a 3D printed object used to initialize plastic is coming out of the nozzle before beginning the actual object print, to add better adhesion of the object to the bed of the 3D printer and check the current adhesion of build material to the print bed.
A computer program used to convert a digital 3D model in to the instruction set or g-code file to be followed by the 3D printer. One part of the process of conversion is to cut the 3D model into layers (or slices), hence the name.

In FFF/FDM printing, they are disposable parts of a 3D printed object designed to temporarily brace parts of an object during printing that cannot hold themselves up. These braces are designed to break-away or wash away after completion of the print. In SLA/DLP technologies, they are used to keep the parts from floating away before they attach to the main body of the object as it is fully printed.
