   * *Cartridge replacement:* Ask Nasa or Wolfgang first. The replacement procedure is described [[#ObjetAlaris30ReplaceCartridge][here]].
   * *<font color=red>WARNING!!</font>* Liquid printing [[#MaterialSec][material]] is toxic: =[[%ATTACHURL%/msds_001.pdf][msds_001.pdf]]=. Use gloves and/or goggles if needed.
---+++++ Quickstart

*Note:* if your model is large, or you need precision, or no prints were run in the last month (check the job manager for a list of past jobs), print =bizcard.stl= (8gms model and 8 gms support, 21 minutes to print) first to make sure that the printer is in order. If you are not happy with the quality, calibration tests like the pattern test and the weight test might be necessary. Contact Nasa.

   * Model and export a binary STL file (see the "Google Sketchup" section below for a ASCII to binary converter).
   * Copy to the computer with Objet Studio installed
      * The two computers are connected via KVM switch. Double-press scroll-lock (it will beep) then press enter (on the black keyboard) to toggle between them
   * Ensure control application started on other computer (Alaris30 on the desktop), and press the red button on the application to bring the printer online
   * Open new tray in Objet Studio and use drag-and-drop to import your STL files (multiple files ok)
      * Make sure the unit is right (inch, mm)
      * Press auto-align toolbar button (it will probably fail). Manually drag object around to non-overlapping positions. For each object, click it and adjust rotation to make it lie down flat. Use the transformation dialog in the bottom left, experiment with rotating by &plusmn;90 in each axis. After getting rotation correct, try auto-aligning again.
      * Choose from glossy or matte finish (top faces only)
      * Support can be light, medium or strong (strong for overhanging structures).
   * Press the model-check button to see if anything is overlapping. If not, there will be no output.
   * Press the material check button. It will display amounts in the status bar at the bottom. Compare these to the levels listed in the main printer application on the other computer.
   * Start the print job. 

   * Use the spatula to pick up the parts. Be careful of hitting the head by chance.
   * Clean the tray: Scrape off the excess support material from the print tray with the scraper. Spray some water on the tray and wipe off with a lint-free microfiber cloth. (Supplies are in the box under the table).

---+++++ Resuming a print

   * Note the "last slice" number =x= from the printer controller machine
   * Hit the resume button on the Job Manager, and enter =x+1= (NOTE the +1) when prompted for the start slice number. (here is why you need to know =x=: the printer can stop printing because of an error or because you paused it -- but the job manager wouldn't know precisely at which slice (=x=) the printer stopped because the job manager sends out 8 slices at a time to the printer)

   * You can pause a print from the host machine if you need for example to take out a part that is done.

---+++++ Troubleshooting

   * If the connection between the client computer (where OBJET studio runs) and the host (printer control program runs on this machine) fails, reboot the client computer. User/Password for the client computer are: admin/admin.

   * *Intro videos:* =[[http://www.objet.com/eLearning/eLearning2/menu5.html]]=

---+++++ File types accepted for printing:
   * *Binary* STL files: from the CAD app. If you have an ASCII STL file, use Brad's script =[[%ATTACHURL%/stl_ascii2bin.py.txt][stl_ascii2bin.py]]= to convert (usage: =python stl_ascii2bin.py --input myasciifile.stl --output mybinaryfile.stl= ).
   * SLC files: rasterized layer files
   * BMP files: Can be sent only from the printer control app, not from the host.

---+++++ Resolution tips
   * Max resolution: 28microns in the Z direction, 1200dpi in X,Y. 
   * Set "angle" low in CAD software for smooth curves
   * Keep &plusmn;8 thousandths of an inch space between parts that fit together.
   * wall thickness: .5 mm, place walls along X (left-right) direction

<!--
---+++++ Preparing the model
   1. Create .stl files in CAD app in “binary” format. Ascii format files are sometimes rejected.
   2. Load STL file on the object software (on the client or host) 
   3. Use scale if the model is bigger than what it should be.
   4. Start with auto placement. Then use “orientate for minimal support”. Manual placement is possible.
   5. “Export your tray as packed job” to objzf format. Take it to the host machine, “import packed job” from file menu.


---+++++ Printing
   1. From object studio on host, load the tray file, send to print. Job manager will run and start sending the layers as soon as the printer is online.
   2. Head nozzles can be clogged, but it is not a problem as long as 7 nozzles are not clogged in a row.
   3. If you need to pause printing, it is better to pause it from the host. 
   4.
---+++++ Finalizing the print
   1. Use a water jet (we don't have one installed -- use a knife for now :) ) for cleaning off the support material. “Lite” support is easy to clean. For some cases, !NaOH might be needed (see pdf).
   2. Color the model, coloring works well.
   3. Try not to use a big drill; gradually increase drill size, otherwise, the model might break.

---++ Hardware
   * *Alaris30:* The 3D printer equipment. Runs Windows XP. Installation disks supplied.
   * *Host machine:* 
      * OS: Win XP. Vista printer driver in beta.
      * RAM: 4G
---++ Software
   * *Control Application:* Use to set printer online.
   * *Objet Studio:* Runs on host or clients. Used to place models on the tray, to get estimates in terms of amount of material. From the host machine, sending to print would run the job manager and start printing.
   * *Job manager:* Does the rasterization and sends 8 layers at a time to the printer. It must be running while the printing is being carried out. Closing this application would forfeit the print.
   * *CAD application:* (third party sortware)
      * *solidworks* (crazy expensive) is used to create/edit models. Save in binary format, high triangulation of models would result in smooth curves. 
      * *Google !SketchUp* (Windows only) (last tested with version 8) is freely available and works well for our purposes. It does not output STL files, but the plugin =[[%ATTACHURL%/skp_to_dxf.rb][skp_to_dxf.rb]]= will allow for export to ASCII STL file (via the Tools menu in !SketchUp). Make sure to clean up the geometry before export, and don't export guide lines. The exported STL file must be converted to binary format for use in Objet Studio. Use the attached =[[%ATTACHURL%/stl_ascii2bin.py.txt][stl_ascii2bin.py]]= script to convert it.
      * *OpenSCAD* (Linux, MacOSX, Windows + FREE) [[http://openscad.org]] yet another open source CAD program. Uses a different "programmatic" approach for defining the parts instead of a visual one. Can output ASCII STL files, use above converter.
      * *Ashlar Vellum Argon* (There might be a 30-day trial period with this one) [[http://www.ashlar.com/sections/products/argon/argon.html]] a professional 3D CAD software, offers a monthly rental model ($40/month, minimum two months).
      * *Free-CAD* [[http://sourceforge.net/apps/mediawiki/free-cad/index.php?title=Main_Page]], cross platform, open-source CAD software. Can be scripted using Python. Seems to be missing a way to indicate resolution of round objects in STL export.
