Remove existing resin as much as possible. Reference - Regarding how to clean the platform, refer to “Platform of 5. Maintenance”. 3-13 Printing 3 2 Cleaning the resin tank Clean the release film and walls of the resin tank using isopropyl alcohol (IPA) and a paper towel. clean it using isopropyl alcohol (IPA) or glass cleaner and a microfiber cloth if required. Caution - For details on how to clean the resin tank, refer to “Resin Tank of 5. Maintenance”. 4 Checking Printed Output Sindoh A1 SD Series USER MANUAL Checking Printed Output 4-2 4 1. Checking Printed Output Caution - Wear nitril gloves before getting started. 1.1 Detaching Printed Output 1 Standby Until Platform Returns To Ready Position After printing is finished, wait until platform completely returns to ready position. Do not open the orange cover before platform stops moving. Platform 2 Platform Locking Knobs Removal When platform stops moving, open the orange cover and remove two platform locking knobs by turning them in counterclockwise direction. Important - Be careful not to drop knobs into resin tank when removing them. The release film of the resin tank or LCD protective glass may be damaged. Platform locking knobs 4-3 Checking Printed Output 4 3 Platform Locking Screws Removal If not removing the resin remnant sufficiently , the table, work area or machine exterior may become contaminated by the overflowing resin from the platform when carrying the platform. As shown in the picture below, please place the platform over a resin tank that resins accumulated on the platform drop to the resin tank. Please remove the remaining resin by scraping with the scrapper shipped with the machine. Important - Be careful not to drop or splash resin to other parts but resin tank. Move the metal scrapper slowly so that resin falls into the resin tank at the edges of platform. - Be careful not to damage the output on the platform during the operation. Caution - The blades and edge of the metal scraper are very sharp, so be careful not to injure yourself when scraping the resin. 4 Detaching the printed output from platform Remove the platform and move it to cleaning tray enclosed in finisher kit. Tray Checking Printed Output 4-4 4 Important - As moving the platform away from the machine, be careful not to let the resin splash or spill onto any part of the resin tank. Insert blade of metal scrapper between printed output and platform and detach it by pushing scrapper slowly and carefully. Start detaching from corners of printed output and continue to insert scrapper inward. At every corner, there are specially designed protrusions that let the blade of the metal scrapper easily slide into between the platform and prints. Use these protrusions to remove prints from the platform. Reference - Protrusions for detaching prints are available only with A Desktop S/W. - If it is difficult to remove printouts from the platform, remove the printouts by hammering the metal scraper (Using hammer in finisher kit) Caution - The blades and edge of the metal scraper are very sharp, so be careful not to get injured when removing the output. - Be careful not to damage the metal scraper by touching the output. - When removing the print object from the platform, please be cautious not to damage the platform surface with a scraper.Damage to the platform surface can result in severe damage to the release film or affect printing quality.Therefore, remove the protrusions on the platform surface completely . - For some brittle resins, pay attention to breakage when removing the sculpture from the platform. If necessary, it is recommended to create a support in the output and print it. 4-5 Checking Printed Output 4 - After removing the platform from the unit, be sure to close the orange cover. If the resin contained in the resin tank is exposed to external light for a long time, the resin may harden and cause the printing failure. 1.2 Finishing the Printed Output 1 Removing supports Remove supports using the nipper enclosed in the finisher kit. Nipper Caution - Use the nipper with care because the blade is sharp. - Be careful not to cut the printed output by mistake. 2 Cleaning the printed output with isopropyl alcohol (IPA) Pour isopropyl alcohol (IPA) in the washing tub enclosed in the finisher kit, and put the printed output in IPA to remove remaining resin. Shake it to facilitate removing resin. Cleaning Container Caution - Do not place the IPA close to fire because it is flammable. Checking Printed Output 4-6 4 Remove remaining resin using a brush or toothbrush. Use a sprayer to wipe out the fine gaps or holes in the output with IPA. 3 Drying and post-curing Important - The curing time may vary depending on the printed output’s size and shape. - For quick curing, f…
