- | * After the print is completed, slide out the build platform with the part attached and place it into a plastic bin with absorbent pad to catch any resin spill. | + | |
- | * Close the orange cover | + | |
- | ====Using the Form Wash:==== | + | ====Blade Selection==== |
- | * Transport the part and build platform in the container to Fume Hood #4 in Elings 2442. | + | * CBN Bond blades are used for cutting ferrous metals. Metal bond blades <1,000 RPM, Resin bond blades >1000 RPM |
- | * Wear a lab coat and safety goggles, as the Form Wash contains IPA. | + | * Diamond Metal Bond blades: high concentration blades for general use at high or low speeds, low concentration blades for ceramics, Silicon, glass. Cut at low speed ,1,000 RPM |
- | * Press ‘Open’ | + | * Plated blades (diamonds nickel-plated to the rim) are good for cutting plastics, PCBs and composites. Cut at low or high speeds |

- | * Refer to the webpage “Form Cure Time and Temperature Settings” through the Formlabs website for resin specific information. A longer cure time (up to an hour) will slightly increase the tensile strength of the part. | + | * Fence \\ {{: |
- | * Press ‘Start’ | + | |
- | * Lift the cover and remove the part once the post-curing has completed. | + | |
- | **Post Processing:** | + | ====Using the TrimSaw 2:==== |

+ | * Slowly | ||
+ | * When cut is complete withdraw | ||
+ | * Using paper towels wipe the Trimsaw down and clear any dust particulates from cutting | ||
- | **Replacing an empty resin cartridge with a full one of the same type:**\\ | ||
- | More information on the resin system and changing a cartridge can be found on the webpage | ||
- | “Formlabs Resin Tank Information” through the Formlabs website. | ||
- | - Remove the empty resin cartridge: | ||
- | - Close the vent cap at the top right of the resin cartridge to prevent resin from spilling out once removed | ||
- | - Hold the cartridge handle and lift to remove from the Form 2. Store the cartridge upright with the valve cover installed to protect storage surfaces from resin. | ||
- | - Insert a new resin cartridge: | ||
- | - Shake and rotate the new resin cartridge to ensure that the resin is mixed thoroughly. | ||
- | - Align the cartridge with the opening at the back of the printer. Push down on the cartridge handle until the top of the cartridge is level with the printer. | ||
- | - Press open the vent cap to ensure the resin tank can fill correctly | ||
- | ====Switching a printer from one type of resin to another==== | + | **Post Processing:** |
- | More information on the resin system and changing a cartridge can be found on the webpage | + | |
- | “Formlabs Resin Tank Information” through the Formlabs website. This includes videos and | + | |
- | animations. | + | |
- | - Remove the build platform - this prevents resin from dripping onto the glass | + | |
- | - Remove resin cartridge: | + | |
- | - Close the vent cap at the top right of the resin cartridge to prevent resin from spilling out once removed. | + | |
- | - Hold the cartridge handle and lift to remove from the Form 2. Store the cartridge upright with the valve cover installed to protect storage surfaces from resin. | + | |
- | | + | |
- | - Hold the front tabs of the resin tank | + | |
- | - Gently pull the front tabs of the resin tank to release the tank feet from the tank carrier. The Resin Tank LT wiper ejects during removal. | + | |
- | - Cover the resin tank and store on the left side of the fume hood | + | |
- | - Insert the resin tank for the resin that you plan to use | + | |
- | - Lift the Form 2 orange cover. Use the tank grips to hold the Resin Tank LT, with the wiper resting inside the tank. If the tank contains resin, cover the tank with the plastic lid to align the wiper and minimize the risk of spills during insertion. | + | |
- | - Align and insert the four small feet of the resin tank into the corresponding slots in the tank carrier on the printer. | + | |
- | - Hold the front tabs and carefully push the tank until the tank feet lock into the slots on the tank carrier. Check the touchscreen display to confirm that the Form 2 detects the tank. The Form 2 will only detect the tank when the tank is fully inserted. | + | |
- | - Lock the wiper blade | + | |
- | - Align and insert the wiper foot into the wiper mount. | + | |
- | - Push the wiper toward the tank. | + | |
- | - Ensure the wiper foot is securely locked into the wiper mount. | + | |
- | - Insert resin cartridge: | + | |
- | - Shake and rotate the new resin cartridge to ensure that the resin is mixed thoroughly. | + | |
- | - Remove the protective valve cover from the underside of the cartridge. Use the cover to protect the bite valve during storage. | + | |
- | - Align the cartridge with the opening at the back of the printer. Push down on the cartridge handle until the top of the cartridge is level with the printer. | + | |
- | - Press open the vent cap to ensure the resin tank can fill correctly. | + | |
- | - Replace build platform | + | |
- | - Make sure that all of the resin tanks are correctly labeled. | + | |
====Maintenance==== | ====Maintenance==== | ||
- | * Cleaning | + | * Blade Cleaning |
- | * Use the scraper from the finish kit to inspect | + | * Cutting blade can become loaded with material despite coolant |
- | * Check for the following issues that may lead to print failures or any excessive wear that requires replacing | + | * Using the Miter guide, load the silicon carbide dressing stick onto the saw and feed slowly into the spinning blade about two to three mm. \\ {{: |
- | * cured resin on the elastic layer | + | * Lubing threads |
- | * debris or failed prints | + | * The aluminum blade retaining nut is prone to cold welding |
- | * settled pigment on the elastic layer | + | * To prevent thread galling a small amount of silicone grease must be applied to the arbor prior to threading on the retaining nut. |
- | * punctures, cuts, or gouges | + | * Emptying coolant |
- | * excessive “clouding” or wear in the elastic layer | + | * When not in use for long periods, |
- | * Filtering Resin | + | * To prevent staff from having to clean this, if the TrimSaw is not in use for over a month it is advisable to drain the coolant tank |
- | * Use a filter | + | * Draining coolant can be done with the ball valve on the rear of the saw and should be emptied into a container for safe waste disposal. |
- | * Cleaning the tank window | + | * Rinse coolant tank twice with water after coolant has been emptied. Water can be disposed of directly into the sink |
- | * Never use IPA on the acrylic | + | * Leave Trimsaw open to allow complete evaporation |
- | * If dust, fingerprints, | + | * Filling coolant |
+ | * Fill the TrimSaw coolant | ||
+ | * Add 120 mL of Coolmist coolant concentrate | ||

- | ====Maintenance==== | + | |
- | * Switching resin types | + | |
- | * Close breather valve on resin cartridge | + | |
- | * Remove the resin cartridge by pulling straight up on the handle behind the form labs printers | + | |
- | * Cap the cartridge valve using the included orange tap and cap | + | |
- | * Remove the wiper by pulling straight out towards the front of the fume hood. | + | |
- | * Pull the resin tray out of the printer by pulling firmly straight out toward you | + | |
- | * Lift the wiper and resin tray out simultaneously, | + | |
- | * Cover resin tray with black plastic cover and label | + | |
- | * Replace resin tray with clean or desired resin tank. Push tank and wiper firmly back toward the Form 2 until it clicks into place | + | |
- | * Replace resin cartridge and open valve | + | |
+ | ====Switching Blades==== | ||
+ | * Insert the two pins into the saw arbor and blade retaining nut normal to the surface of the arbor | ||
+ | * Using the leverage on the pins, loosen the blade retaining nut to free the blade | ||
+ | * Carefully remove the blade from its arbor and replace with the blade matching the material you intend to cut | ||
+ | * Lightly LUBRICATE the threads on the end of the blade arbor with a grease to prevent thread galling. | ||
+ | * Tighten the blade retaining nut HAND TIGHT (no need to go crazy on this) | ||
+ | * Insure the coolant level is in contact with the bottom of the blade and filled to the fill line | ||
