Congrats! You’ve made it past printing the parts for the BotBQ and collecting all the vitamins and you are ready to adjust your 3D Printer Firmware and slicer settings….. We getting closer to loading up the Hamburger housing with your preferred meat of choice and firing off your first 3D Printed Burger! The idea behind this initial extruder design is to make it easily adaptable to many printers, and not to difficult to adjust your firmware and software settings.
- Before you do anything in this section… MAKE SURE YOU BACKUP YOUR CURRENT FIRMWARE!
- If you need to get familiar with 3D printer firmware go here: http://reprap.org/wiki/Firmware
- It is pretty simple to do. Just copy your firmware folder and paste it in a location you’ll remember so you can use it in case something goes awry. In a future post I may go into this a little bit as I haven’t found something online that explains it in detail.
Adjust your “Z_HOME_POS” to correct measurement with your specific nozzle/hamburger housing.
Comment out the “EXTRUDE_MINTEMP” so that your printer will not give you a “cold extrusion prevented” error, as we will not be using heat while extruding out meat.
Here we get to slice your “burger design.” I currently use Slic3r by the awesome Allessandro Ranellucci. I have also fooled around with Skeinforge in my early days with 3D Printer Firmware, but I only recommend it now for advanced RepRappers. I haven’t messed around much with Cura yet, but I will soon as my favorite Open Source 3D Printer Software, Octoprint is about to have Cura merged in it, with a lot of help from the amazing Ross Hendrickson.
So the examples below will be in Slic3r but can be adapted to your preference slicing software none the less.
Load up your burger design in your slicer of choice. I recommend for your initial go, design your thickness at least the same size as your first layer height (see below) until you have your configuration figured out.
Your custom burger shape can be as thick, wide and long as you like.. but I chose a thickness of 13mm at my first go.
Your infill is up to you. You can get creative and do some honeycomb shaped infill with 10% infill, or you can fill that thang up and do your regular burger like the good old BK.
Speed is something that I haven’t played too much with as far as printing burgers go, but for this round I went for 30mm in all options just to be safe and not have any more burger explosions since the initial test. Once I play with this setting some more I will be sure to let you know how it goes.
Skirt and Brim:
Unless you want some worm shaped burger strings I suggest you make sure these settings are all at 0.
ATTENTION: Make sure your “Filament Diameter” and “Nozzle Diameter” are the correct size as the top of your Hamburger Housing…. this may take a few times to perfect (as you can see in my burger explosion) but making sure your nozzle size and filament size are right, or your demise is imminent!
Ready to go:
You can now export your .stl file to gcode and load up into your 3D Printer with the BotBQ Extruder attached and print your first 3D Printed Food Hamburger!!!!!!!!
Are your excited??? I am excited for you…. You know what you should do next? You should share your experience on this site, or any of the social media channels that BotBQ is on so THE WORLD CAN SEE!!!! I am all about helping whoever needs it, and especially when it comes to 3D Printed Food. So comment here or wherever and I’ll help however I can. I am soooo excited about 3D Printed Food that I want to see what you are doing with it and how we can work together to move this platform further.
