 +  * Max Build Volume: ''64 × 40 × 134mm''
 +
 +<WRAP center round important 60%>
 +  * Be mindful working with resin. It's a carcinogen, which means that every time you come into contact with it, it increases the damage to your body.
 +  * Be gentle with the resin trays. The window can be damaged easily. Only touch it with the rubber spatula when cleaning the tray.
 +</WRAP>
 +==== Pre-print ====
 +  * Check if your 3D object complies with the [[autodesk_ember:autodesk_ember#resin_design_guidelines|Design guidelines]]
 +  * Get the workspace ready
 +    * Get nitrile gloves
 +    * Get safety goggles
 +    * Get paper towels
 +    * Put a Silicon mat in front of the printer
 +    * Get the alcohol spray bottle
 +    * Get pots with alcohol (IPA)
 +    * Get resin and used resin bottle
 +  * Load model in Print Studio and position accordingly. 
 +    * Uncheck the support-icon in the object browser when you want to print without auto-supports. \\ {{:autodesk_ember:auto_support_setting.png|}}
 +    * Select the actual resin you're going to use. This affects the print settings.
 +  * [[autodesk_ember:autodesk_ember#Find volume of object (for material calculation)|Calculate cost]]
 +  * Roll the resin bottle between your hands to stir the resin without making too much bubbles. 
 +  * Fill tray with resin. **Respect the MIN MAX indications.**
 +  * Start the printer
 +  * Do the calibration
 +
 +==== Post-print ====
 +  * Open alcohol pots
 +  * Put an open waste basket near the workstation
 +  * Put paper towels next to silicon mat
 +  * Put on goggles and 1 glove
 +  * Take the print head out and remove the part with the spatula. Keep the blade parallel to the surface to prevent damage to the head.
 +  * Put the part in the 'dirty' alcohol pot with tweezers and shake the bottle for 3 minutes.
 +  * Clean the tweezers with alcohol and take the part out of the alcohol container.
 +  * Dry the part with a paper towel.
 +  * Clean the build plate and put it back in the printer.
 +  * [[autodesk_ember:autodesk_ember#get_the_printer_ready_for_downtime|Get the printer ready for downtime]]
 +
 +
 +==== Get the printer ready for downtime ====
 +Don't leave resin in the vat for more than 2 days.
 +
 +  * Pour resin from the resin vat into the 'used-resin' bottle.
 +  * Clean the resin vat.
 +    * **Do not touch the window with anything other than the yellow rubber spatula.**
 +    * Use the yellow rubber spatula to remove most of the resin.
 +    * Use a paper towel soaked into alcohol to clean up the remaining resin.
 +
 +It is possible to store the resin vat in the printer for medium periods of time. For longer periods, put the vat in a air sealed bag and store in a light tight cupboard.
 +
 +
 +==== A failed print ====
 +  * stop the printer
 +  * filter the resin from the vat through a single use funnel
 +  * with the yellow rubber spatula, gently rub the window of the vat, to make sure nothing sticks to the window.
 +  * pour the filtered resin back in the tray
 +  * rethink the 3D model and or the print setup and try again.
 +
 +==== Find volume of object (for material calculation) ====
 +When the object is set up in Print Studio, go to the Layout tab, select the Scale tool and select the object.
 +The dimensions appear on the bounding box.
 +
 +{{:autodesk_ember:print_studio_dimensions.jpg?600|}}\\
 +Note one of the dimensions and open the file in Blender. //(In this case the Z-axis)//
 +
 +{{:autodesk_ember:blender_change_scale.jpg?600|}}\\
 +Change the units to Metric, and set Length to millimeters. Scale the model until the size matches the chosen dimension in Print Studio. //(The dimension is Y in this case since the object was reoriented in Print Studio)//
 +
 +{{:autodesk_ember:blender_volume.png?600|}}\\
 +In the ''3D-Print'' add-on, click the button ''Volume'' under Statistics. The volume is reported in cm3. Multiply with 1000 to get mm3.

 +==== Resin design guidelines ====
 +  * Make sure the supports do their work during printing (not only at a completed print).
 +  * Orient faces that need to be clean away from the build platform.
 +  * Keep wall thickness in mind. It might show up fine in the slicer, but it can ruin the print. As you can see in the example: what should've been a continuous cylinder are now 4 separate walls. The wall thickness on the thinnest parts in the red circles is ''0.19mm''. \\ {{:autodesk_ember:thin-wall-failure.jpg?600|}}
 +  * Avoid large surfaces coming into contact with the build plate. This creates suction and peeling of the newest layer. Tilt the model on 2 axes and support the islands in the slicer.
 +==== Workstation guidelines ====
 +[[https://www.youtube.com/watch?v=onVNnRjbm5g|Source]]
 +
 +  * Keep resin contamination to a strict minimum. Only the following parts can be touched with resin-contaminated gloves.
 +    * build head
 +    * spatula
 +    * tweezers
 +    * funnel
 +  * **Keep all other parts and surfaces clean!**
 +  * Use a [[https://www.amazon.nl/Voedselkwaliteit-Verdikking-Anti-overloop-Multifunctionele-Voedselzak/dp/B07H79WDS3/ref=sr_1_2?__mk_nl_NL=%C3%85M%C3%85%C5%BD%C3%95%C3%91&dchild=1&keywords=silicone+mat&qid=1597823179&sr=8-2|silicone mat]] to catch resin drips
 +  * Wear goggles to protect your eyes from accidental splashes of resin
 +  * Wear nitrile gloves - (throw away after use, or clean them thoroughly with alcohol)
 +
 +==== Calibration ====
 +
 +Necessary after 
 +  * a failed print
 +  * a changed resin tray
 +  * a changed build head
