-====== Autodesk Ember ====== +===== Autodesk Ember ===== 
 +  * 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. 
 +==== 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. 
 +Note one of the dimensions and open the file in Blender. //(In this case the Z-axis)// 
 +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)// 
 +In the ''3D-Print'' add-on, click the button ''Volume'' under Statistics. The volume is reported in cm3. Multiply with 1000 to get mm3. 
 +==== How much does it cost? ==== 
 +( resin amount (in liter) * resin cost * material multiplier ) 
 +  + 
 +( machine time (in hours) * machine time multiplier ) 
 +  * resin amount: calculate the volume of your model in a 3D application. Then calculate this amount in liters: 
 +  * Volume of 3D model (mm3) * ( 10 to the power of -6 ) 
 +  * resin cost: €108,00 per liter 
 +  * material multiplier: 30%: material cost *1,3 
 +  * machine time multiplier: €0,55 per hour 
 +==== 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 ==== 
 +  * 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 [[|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
