− | * If a window pops up saying the print is broken, hit the repair button then proceed as normal
| + | ### Pros: high detail, matte surfaces, good for small, intricate features. |

− | * All prints should be slightly canted (angled) to prevent the delamination process from removing the print from the build plate
| + | === Changing Resin === |
− | ** The goal is to reduce the horizontal area covered with each pass of the wiper
| + | # Remove, clean, and replace the build plate. |
− | ** Start with auto-orienting the part using the 'Orient Selected' button in the Orientation tab, this is a good place to start and will make it easier to see if the part needs further orientation
| + | ## Pull lever holding build plate in place up, allowing the build plate to be removed. |
− | * Don't place supports on hard edges (right angles) or in inaccessible places
| + | ## Place the build plate on the holding rack in the Form Wash. Run the build plate through the Wash to remove resin. For the build plate, the Wash should be set to 10 minutes. |
− | * Supports should be used in accordance with the part
| + | ## Let the build plate air dry before replacing, secure by flipping lever down. |
− | ** Every part that needs support should have support - PreForm will highlight unsupported areas in red, place supports until the red areas go away, '''check the part thoroughly'''
| + | # Remove and replace resin tank and wiper. |
− | *** Preform shouldn't let you print with unsupported areas
| + | ## Firmly pull wiper back until it's out of its slot and loose in the resin tank. Leave the wiper in the resin tank, each tank has its own wiper. |
− | ** Supports can be added, edited, and removed in the PreForm Supports tab
| + | ## Firmly pull tank back until it pops loose of the printer, put the appropriate lid on the resin tank, and store with wiper in tank. |
− | *** Support density should be between .5 and .7
| + | ## Before inserting the new resin tank, remove its lid and store. |
− | *** Support point size should be between .6mm and .8mm
| + | ## Slot the new resin tank into place in the printer. |
− | *** These values can be edited if necessary to ensure printability, just use common sense when adjusting values
| + | ## Use a scraping tool to dredge bottom of new resin tank for any hardened resin or loose bits of material, remove any found bits. |
− | ** Larger prints will require more support than smaller prints | + | ## Slot the new tank's wiper into place. |
− | * The Layout tab can be used to add additional copies of a part
| + | ## Be sure to clean up any resin that spills during this process. |
− | * Ensure the proper printer and resin type are selected in Preform prior to starting the print | + | # Remove and replace the resin cartridge in the back of the printer. |
| + | ## Close the lid of the cartridge if it's open. |
| + | ## Pull cartridge out of the printer. |
| + | ## Wipe dry the resin drip on the bottom of the cartridge, then store. |
| + | ## Insert new resin cartridge, '''of the same resin as the tank'''. |
| + | ## Open lid on resin cartridge before starting a print, and close after. |
| + | |
| + | === Removing Prints === |
| + | # Finished prints |
| + | ## Use a scraping tool to remove the print and any extra material from the build plate, taking care to not scratch the build plate. Go as carefully and as slowly as needed to prevent damaging the print. |
| + | ### The build plate stand can be used for easier removal. |
| + | ## Wash the print in the Form Wash. |
| + | ## If the print is being cured, only remove support material after it has been run through the Form Cure. |
| + | ## Supports should be clipped off, and any leftover support material can be sanded down if desired. |
| + | # Failed prints |
| + | ## Follow the same process for finished prints for removing. |
| + | ## '''When a print fails, the build plate must be cleaned and run through the Wash''' before a new print can be started, as leftover residue from the failed print can cause subsequent prints to also fail. That's bad. |
| + | |
| + | === Washing and Curing Prints === |
| + | See the [[Form Wash and Cure]] page. |
| + | === Common Errors === |
| + | If a print fails, the most likely cause is contamination of the resin. Before proceeding, see the procedure for Failed Prints. Contamination of the resin involves leftover material on the build plate, or particulates in the resin tank. Before attempting a new print, thoroughly clean the build plate, and dredge the resin tank for any loose particles. Another cause is incorrect orientation of the print. Check the print file in question, and ensure it has been canted accordingly to prevent the de-laminating process from removing the print from the build plate. '''Don't ever mix resin types.''' |
| + | |
| + | Old resin and resin tanks can also present issues. If a resin tanks is particularly cloudy on the bottom, the laser will be prevented from being able to penetrate the tank, and cause adhesion issues for the print. Resin can also go bad after sitting for long periods of time or being used heavily. This can be evidenced by discoloration of the resin or separation of the resin into unmixed layers. |
| + | |
| + | === Maintenance === |
| + | * Dredging: Every few prints the resin tank should be dredged with a scraping tool to search for any hardened resin or loose bits of material, when resin tanks are switched out, and when a print fails. Remove any found bits. Dredging is done by sweeping a scraping tool back and forth across the bottom of the resin tank, essentially mixing up the resin to stir up any loose bits. Take care while dredging to not scrape the tank. See a resin's particular page on the Formlabs website for additional cleaning instruction. If the tank is not cleanable, switch out the resin tank. If the problem persists, it's possible the resin cartridge needs to be switched out as well. |
| + | * Alcohol in the Form Wash must be changed once a certain threshold of washed-off resin enters the tank. See the [[Form Wash and Cure]] page for details. |
| + | * Old resin and resin tanks will occasionally need to be changed out |
