| 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.

| + | * If you experience a fire alarm while working in the Welding Lab turn off the welder power/exhaust fan if you safely can and proceed to the nearest safe exit. |
| + | * Make sure the materials have no coatings. Welding of some coatings like cadmium plating or galvanized metal can produce toxic fumes that could be fatal. |
| + | * Argon acts as an asphyxiant and will displace oxygen. Do not work in a confined space with argon do to the possibility of a low oxygen condition. |
| + | * When setting gas pressure for any of the welders make sure you follow the recommendations listed. |
| + | * Materials should be properly prepped and clean for best results. |
| + | * Make sure the process you are using is correct for your material type. |
| + | * Double check the weld settings and use a piece of scrap to practice before welding on your project. |
| + | * Only weld steel and aluminum. Do not attempt to weld unknown materials. |
| + | Here are a couple things to keep in mind: |
| + | * Material will be very hot after welding so always think before touching. |
| + | * Make sure the welder is properly grounded before attempting to weld. |
| + | * Never weld in wet clothes or around water. |
| + | * Never try to weld any type of tank that has ever held flammable liquids. This is very dangerous and can explode! |
| + | * Always check your welding hood settings prior to welding. (start with a darker setting and work your way down. |
| + | * Welding takes lots of practice so don't be afraid to ask for help. |

− | [[File:InvertedSLA.png|302x302px|thumb|right|Inverted SLA Process]]
| + | Bead blasting is the process of using compressed air to propel small glass beads for ablating and cleaning a material surface. Different types of blast media are used in industry including Soda, Walnut shells, Sand and many more material types.<br><br> |
− | 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.
| + | These are a few good steps to having Success with glass beading. |
− | The Form 2 is the only 3D printer that the Prototype Lab has that is an SLA printer. It utilizes the Upside Down or Inverted orientation.
| + | * Make sure the material is free from heavy grease and dirt. |
− | The resin tank has a clear bottom with a surface the resin will not stick to. This allows the resin to cure against the bottom of the tank.
| + | * The material needs to physically fit into the blast cabinet. |
− | The build platform is lowered into the resin until it is hovering above the bottom surface of the tank, as far away as the height of the layer to be constructed. | + | Here are a couple things to keep in mind: |
− | The laser is directed through the bottom of the tank and cures a layer of resin onto the build platform. Then, the resin tank slides over and the build platform raises. The wiper will then sweep across the tank to circulate the resin.
| + | * Never point the nozzle at the gloves or window. |
− | The build platform will lower again, and the process will be repeated until the print is completed.
| + | * Make sure the power switch is turned on before use. |
− | Due to friction caused by de-laminating every layer, every part should be canted in its orientation. This means the part should be angled to reduce the cross sectional area needing to be shifted to de-laminate each layer. This de-lamination also causes the Form 2 to be the Prototype Lab's slowest 3D printer.
| + | * Always wait 5 minutes after use before opening the cabinet door. This gives some time for the dust to settle. |
− | Once a part is finished on the Form 2, it must be removed off of the build plate. Try to avoid scraping the build plate when removing parts. Any excess resin must be washed off using the Form Wash, the part must be air dried so that any isopropyl alcohol from the Wash has evaporated, the part should be cured in the Form Cure, and supports should be clipped off. Any remaining support marks can be sanded off if so desired.
| + | * Never try to bead blast anything flammable. Blasting can sometimes create sparks. |
− | Extra information on SLA Printing can be found [https://formlabs.com/blog/ultimate-guide-to-stereolithography-sla-3d-printing/ here].
| + | * Keep liquids out of the cabinet. |
| + | * Never activate the foot pedal with the cabinet door open. |

− | 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.

− | Both Stratasys printers (Dimension and F370) use soluble support filament (the support filament dissolves in a heated sodium hydroxide bath), the Prusa printers use only a model material, and the Markforge printer only uses model material as well (however it will layer another filament for extra support).
| |
− | | |
− | The filament for these printers comes in spools (basically thin plastic ropes that are wound up). The filament is fed through an extruder head, heated to the desired temperature, then extruded (similar to what happens with a hot glue gun). | |
− | | |
− | FDM printers can work with various materials, in the Prototype Lab we mainly stick to ABS which is used by the Stratasys machines and PLA which is used by the Prusas. The Markforge uses a material called Onyx (nylon and plastic mix) and will layer in another filament such as Carbon Fiber, Kevlar, etc.

− | ==General Welding Knowledge==
| |
− | Welding is the process of jointing metals. 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.
| |
− | There are a couple common steps that must be done correctly when using the laser cutter:
| |
− | * Always make sure that the lens and cone are clean before starting a print.
| |
− | * Correctly focus the laser above the material, using the correct focusing tool for the lens type.
| |
− | * Choose the correct material profile for the material you are using.
| |
− | * Clean the bed of the laser cutter when you are finished.
