Safety First is the rule we hold highest of the three. Given the delicate nature of our machines, and the different chemicals and materials we use in the Prototype lab, this rule applies to both the safety of you, and the machines.

===2. Reset the Space===
The Prototype Lab has a specific organization to it, even though sometimes it looks like chaos. Put whatever you use back where it belongs. There is a place for everything and everything has a place. This rule applies to everything in the space. If you move a chair, put it back. If you use a tool, put it back. If you use a pen, put it back. Do not leave your projects in the Prototype Lab, take them with you. Do not leave random note sheets that pertain to nothing out. Throw away your trash and recycling.

=== 3. Be Professional ===
===3. Be Professional===
This commandment has two sides to it. It covers the idea of acting like professional (which Webster’s defines as “exhibiting a courteous, conscientious, and generally businesslike manner in the workplace”). The term also describes the standards of education and training that prepare members of the profession with the particular knowledge and skills necessary to perform their specific role within that profession. Hopefully, you are learning both of these as part of your education at George Fox University. In the Prototype Lab we expect you to develop as a courteous, conscientious, and skilled craftsman, understanding the tools and equipment in the Maker Hub and how to use them effectively.

One very important, and likely difficult part of being a professional is to correct others when they are not being professional. It is your responsibility to speak up when you see somebody doing something inappropriate. If you see somebody doing something unsafe, not resetting the space, or being unprofessional, the professional thing to do is to remind them of the three commandments and ask them politely to correct their action. This is OUR space, not any individual's. As a group, we expect everyone in the space to keep the space safe, clean, and operable for everyone.

===1. Printer Types===
There are many different types of printers, such as Fused Deposition Modeling (FDM), Stereolithography (SLA), Selective Laser Sintering (SLS), Selective Laser Melting (SLM), Digital Light Processing (DLP), Electronic Beam Melting (EBM), Laminated Object Manufacturing (LOM), Binder Jetting (BJ)... Each printer type employs different materials. The Prototype Lab has FDM and SLA machines.

Information about FDM and SLA printers and which machines these are and what materials they can use which. In each printer's page, one can simply link it to this so they don't have to describe materials, just simply state which ones are used with it. Mostly this is all here so I remember to do it or someone else sees it and wants to do it.

Stereolithography, SLA, is a part of the manufacturing technology of vat polymerization. This means a light source (laser) is used to cure liquid resin into a hard plastic.

Fused Deposition Modeling (FDM) printers use a thermoplastic filament, which is heated to its melting point, then extruded to create layers which then build an object. There are many different types of FDM printers. Some use a modeling material and a support material, some just use a modeling material which when creating support will use a different style of layering that allows the filament to break off easily, some are able to use multiple filaments at once allowing for multicolored objects to be created.

Laser cutting directs a high-powered laser through optics. The laser cutter follows a predetermined pattern to engrave or cut the material. Laser cutting is a great way to get a professional-looking surface finish.

* Can be used for many different materials ranging between wood, glass, rock, plastics, and even engraving Hydroflasks. At this time, the laser cutter in the Prototype Lab is not set up for metal etching.
* Works best on flat surfaces or cylinders with constant diameters.

*Performing a cut or engrave with the laser will always begin with an image, pdf, DXF, or similar file. When using SolidWorks you will need to save your file as a DXF using the selected face.
