Line 79:
Line 79: − There are common places of potential failure which you should watch for every print. The following points of failure specifically apply to FDM prints. − *Adhesion: − **When the print first starts, it is prudent to ensure that the filament is properly adhering to the build plate. − **Watch the print until the first dozen layers have been printed to make sure it is starting off successfully. − **The print can start sliding around the plate at anytime, although it is much more likely to fail toward the beginning of the print. − **A tall and skinny print is much more likely to struggle with adhesion than a short and stout print. Taking time to discern the best orientation for your print is always a good call. − **Adding a raft (sometimes called a brim) will also help if you print is struggling with staying adhered to the plate. − *Clogging − **Sometimes the extruder will clog causing the print to fail. − **This typically can be seen when a clump of filament balls up at the end of the nozzle. − **If this occurs, immediately cancel the print and remove the clumped filament. Make sure that the nozzle is still able to extrude filament, if not, you may need to open up the extruder and clean it. Keep working on it until you are able to extrude filament again. − *Air Extruding − **This means that the extruder thinks it is extruding filament when it really is not. − **Immediately cancel the print. Then restart the print. − **If the printer is still air extruding, cancel the print and unload the filament. You can try reloading and starting the print again. − **If the problem persists, you will probably need to take the extruder apart and clean it out before attempting any further prints. − === 1. Welder 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.
→General Welding Knowledge
Each welder has its own special purpose and benefits. MIG is fast and much easier to learn than TIG welding. Spot welding is only used with sheet metal. TIG welding produces very clean welds and the heat is more confined to a smaller area. TIG will also allow you to weld very thin metals.
