V1 Safety and Compliance Read the following safety instructions and contents of this manual before use, operation, maintenance, replacement or removal of any parts, components, or materials of the printer. For the latest information about the Nobel 1.0A 3D Printer and XYZprinting products, please visit XYZprinting website (http://www.xyzprinting.com) or contact your sales representative. The following has been written in order to cover all possible printing scenarios. For scenarios which occur outside the scenarios detailed in this manual, the user will be held accountable for their own safety. Important Safety Information:

Do not let children operate this device without adult supervision. Moving parts may cause serious injury. Electric shock hazard. Do not place the printer on an unleveled or unstable surface. Printer may fall or tumble causing harm and/or injury. Also tank level detection may be inaccurate. Do not place any object on top of the printer. Liquid and solid objects that fall into the printer may lead to printer damage or safety risks. Please keep the printer, resin, or alcohol away from fire. Do not disassemble or replace the printer cover with non-XYZprinting covers. Insert and secure the power cord firmly for proper usage and to avoid potential electricity and fire dangers. Do not attempt to service the printer beyond the instructions specified in this document. In the case of irrecoverable problem, contact XYZprinting service center or your sales representative. Do not place the printer in humid or dusty environments such as bathrooms and high traffic areas. Some components of the printer move during operation. Do not attempt to touch or change anything inside before powering off the printer. Please keep the lid closed during printing to avoid injury. This printer is a Class 1 Laser Product. A Class 3B laser module is used as a light source. Never disassemble the product. For optimized printing quality, only use resin supplied by XYZprinting. Make sure to set the power switch to the off position and remove the power cord before transporting the device. Only use the grounded power adapter and power cord supplied with the printer to prevent possible electrical shocking. Please place and use the printer in a well ventilated area. The process of printing will produce a small amount of non-toxic odor. Having a well ventilated area will ensure a more comfortable environment. Resin Care Wear proper protective equipment, avoid raw material contact and vapor inhalation. Chemical-resistant gloves should be worn when you make contact with resin. Avoid exposing resin to high temperatures, localized heat sources (i.e., drum or band heaters), oxidizing conditions, freezing conditions, direct sunlight, ultraviolet radiation, inert gas blanketing. Never pour the waste resin back to the bottle or down the sink, as it may pollute the remaining resin or clog the drain. You may pour resin waste into plastic bag and expose it to sunlight or UV light source to cure the resin. The cured resin can then be discarded. Avoid dripping resin on anything other than the platform or the resin tank, or the printer may malfunction. Resin Tank Care Due to the nature of the print technology and material, the resin tank may develop cloudy regions overtime where the laser cures the resin frequently and may lead to print fails. Moving the print location around the platform can help prolong the life of the tank. Change to a new tank when over 2/3 of the surface gets cloudy. Use a separate resin tank when using resin of different colors. Mixing resin of different color may affect printing quality.

(Overview of XYZware_Nobel) O Functions:

A. Import objects in .stl/.3wn format: Open file browser and select the .stl or .3wn files to print. ".3wn" format is sliced by XYZware_Nobel based on the printer type selected. For the file set to slice for printer type other than "Nobel 1.0A", it will not be printed on this printer. Export to .3wn format: After selecting a desire printout setting, click on "Export" to save the model to a sliced .3wn file. Once the file is sliced, you may skip repeating settings in the future. B. Options under Export :

Good

"Layer Height" indicates the resolution of a print. Using thinner layers will make higher quality prints but will also take longer to print. Printing setup varies based on the color and material of the resin. Please set the option based on the resin cartridge installed on the printer before printing. It is advise to include color setting in filename for instant distinction in the future. The setting of Quality has impact on the smooth-

ness of the surface of the printout. When printing with "Good" quality, the surface with less features will be more smooth. With the setting, it will take slightly longer for printing. Check "Brim" for the 3D objects that has less contact with the platform to increase adhesion.

-8-

V1 C. D. E. Save as .stl file: Save all objects on the platform to a single stl file. Any adjustment to the size or placement of the objects will apply to the stl file. Setup printing preference and send the objects for printing: Once your device is connected to the printer, click "Print" to open printout setting window (options are the same as "Export" window). Set your printing preference based on the features of the objects and hit "Print" to proceed. Setup interface language, display unit, light strength tuning and etc. Tips for Printout Scaling:

If you find the dimension of the printout doesn't match the 3D model, you may adjust the scale of the X/Y axis. The setting will be stored in the software and applied to every print job afterwards. F. G. H. I. Info/Software & firmware update: Apply printer firmware and XYZware_Nobel updates when prompt by the software for stable printing perfor-

mance. Zoom in/out: Zoom in or out the platform to view the details of objects. Switch views: Switch views with a click to view objects from different angles. Support structure: support structure is required under overhangs. It prevents the falling for gravity and the deforming duo to the stickiness during printing, and increases adhesion of the model to the platform.

(mm) Support auto generation: XYZware_Nobel is able to analyze the features of the model and add support structure to where necessary. Simply select a desired density and size , choose to "Lift" the print and/or print without internal support , and press "Generate" to preview the support structure. Density : Large overhangs will require more support structure. However, more support structure will take longer for printing. Size : Thicker contact point will lead to higher strength but will take longer for printing. Lift : Lift the objects over the platform will ease the removal after printing. However, the support structure under the prints will take longer for printing. Inner Support : For objects with inner overhanging structure, XYZware_Nobel will add support to the parts. However the support at inside may not be removed easily, you may consider printing without inner support. Support mark Manual editing: you may add or delete support structure based on the features of the print manually. To add support, simply select a proper size of the contact point and then click on the model at the overhangs. To delete support, just click on the support mark (the blue dot). After setting up support marks, click "Generate" to continue. Tip You may generate support automatically with XYZware_Nobel, and then add/delete the support structure based on your printing experience. Use both functions help to ensure the success of printing, and may decrease resin consumption and shorten printing time. Move the object: move the object along the x, y, or z axis. You may also press and hold ALT key and drag the mouse to move the object horizontally. Rotate the object: adjust the angle of the object around the x, y, or z axis. Flipping the object around to adjust the face on the platform may help to enhance printing performance. Increasing the contact area between the object and the platform may help to enhance printing quality and strength. Resize the object: Scale the object as you desire. The adjustment to the object on the platform will not affect the size of your original file. View info of the object: check the dimension and location of the object, so you can tell the size of the object easily. Remove the object from the platform: select an object and click the option to delete it from the platform. Or you may press Delete key to remove the object. View printer status J. K. L. M. N. O.

V1 Check Before Every Print Check the following items before printing to ensure printing quality and the operation of the printer. Remove any residue or dust from the platform and tank with the scraper, filter or other tools. Mop the fingerprint or resin under the tank or on the glass with with lint-free cloth dampened with alcohol. Brush the level sensor with alcohol if it gets stuck. Level sensor should return to the original position after a soft push. When the tank is full or the resin gets sticky, the sensor's movement may be hindered greatly. It may take 1 minute for sensor to return to normal speed. If stuck, remove the remaining resin from tank before cleaning. If resin in tank is cured, please replace the tank.

V1 Printed Object Removal and Cleaning Resin Tank Cleanup When removing prints from the printer, follow the procedure to post-process the object and maintain your printer. To remove any residue stuck to the bottom of the resin tank, clean the tank level sensor covered resin, or to clean the tank thoroughly, follow the procedure for cleaning:

Remove the platform Wear gloves before removing the prints. Turn the platform locker counterclockwise until it stops. And pull the platform to remove it. Note Always remove the platform before removing the resin tank to avoid dripping leftover material on printer surface. Use the scraper to remove print Note Scrap off the print gently to avoid damaging the surface of the platform. Rinse part in Alcohol (

75% Alcohol) Pour alcohol into the rinse basket, shake the print for 10 minutes, then rub it with your fingers though-

roughly. Cleanup and reinstall Remove any residue in the resin tank. Operate gently to avoid scratching the surface of the resin tank. Reinstall the resin tank after cleaning. Scrap off any residue and remove excess resin from the surface of the platform. Turn the platform locker clockwise until it stops when reinstall-

ing it to the printer. Uncured resin in the tank can be left for future printing. To prevent dust from accumu-

lating on the resin, always cover the lid over the printer after removing any residue from the tank or the platform. Place the printer away from direct sunlight or UV lighting, even if the lid is covered, or resin in tank may cure and solidify. B A Pour uncured resin in the tank into a waste bin. For remaining resin, scrape the surface of the tank gently while pouring the liquid out. Scrape off the residue stuck on the tank gently. Avoid damaging the silicon finish. Clean the tank level sensor if it gets stuck. Loosen the 2 screws

(A&B) above the sensor before dismounting. Then brush any resin in sensor parts and on the floater with alcohol. To mount the sensor on the tank, tighten the screws over the sensor lightly. Avoid over-tightening the screws as the wall may crack. Regular maintenance on the tank level sensor is essential to maximum the service life of the resin tank and ensure the smoothness of the operation. Spray alcohol on the tank and the silicon finish, and wait for around 1 minute. Gently scrape residue and pour remaining alcohol left in the tank into the waste bin. Repeat these steps until all residue has been removed. You can either wait until the alcohol in the tank evaporates completely or wipe away the alcohol with a lint-free cloth. Note If resin in tank is cured, please replace the tank.
