 ====Overview of the printer and software====
 The printer comprises the following main components:

   - Save CAD file in .STL format, bring to printer on a thumb drive.
   - In **Objet Studio insert the file** – you should see the part on the image of the print platform.
+  - Use **auto placement** to allow the printer software to attempt to optimize orientation and part location. Fine tuning by hand may be necessary for best results.
+    - Keeping the part within the horizontal lines outlined on the build platform can reduce the number of passes the print heads must make per layer
+    -  Orientating the part to reduce Z height often greatly reduces print time
+    - Glossy surfaces can only be printed along the top surface of the part where there are **NO** overhangs
   - **Validate** the design
   - Select **matt or glossy finish** for each part
   - Run the **estimator** to determine the print materials required and the print time
-  - Enter this information in the log book
+  - Enter this information in the log book and FBS
   - Press **build**
   - Open the remote desktop connection to the printer

   - Clean the print bed using a paper towel wetted with water.
   - __**Run the head cleaning wizard – the print heads cost ~ $5k and will be ruined if not cleaned after the run!**__
-  - Clean your parts in the water jet cleaner

 ====Post Processing====
+  - Take the part to the 3D print cleaning station by the pressure washer and remove the bulk of the support material with the cleaning implements. **Wear gloves as uncured resin may be on the surface of the part**
+  - Place part within the pressure washer and open the DI valve on the sink. The power switch is located on the back of the washing enclosure.
+  - Using the foot pedal clean the part using the high pressure nozzles located within the enclosure
+  - After part has been cleaned ensure the water is **Switched Off** as leaks have occured within Elings hall before and **will damage equipment**
+  - To achieve optimal mechanical properties or if part is to be used as a mold for casting part should be baked at 60 degrees C for a minimum of 4 hours
 ====Maintenance====
+  * Print heads and roller should be cleaned after EVERY print
+  * Build tray should be scraped free of debris and wiped with wet paper towel after EVERY print
+  * Printer should be restarted once every week or whenever printer is misbehaving.
+  * Head alignment and patterning should be done every month or so to ensure printer accuracy
+  * Waste resin container should be sealed, placed in hazardous chemical waste, and replaced as necessary
