Line 31:
Line 31: − + − * The Form 2 utilizes the Upside Down or Inverted orientation. − ** 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 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. − ** 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. − ** The build platform will lower again, and the process will be repeated until the print is completed. − ** 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. − ** 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. − * Extra information on SLA Printing can be found [https://formlabs.com/blog/ultimate-guide-to-stereolithography-sla-3d-printing/ here].

* The Form 2 is an SLA Printer. 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.
* The Form 2 employs [[SLA Printing]].
