Checklist - read before you begin printing!
- After mounting the toolhead, insert plugs marked LEFT and RIGHT into the respective sockets.
- Activate the toolhead by using the LCD display panel menu. Go to Select Toolhead screen and choose Dual Head Extruder or Dual PRO depending on the toolhead you would like to use. Without it, you can damage the left motor!
- Don’t forget to connect the small left plug (marked as A). It's responsible for the LED lighting on the carriage and the cooling system.
- Remember to calibrate the Z-Axis endstop.
- Prepare the glass bed, so the plastic filament sticks to it well. Read about how to make your prints stick to the bed. It is also recommended that you use Power Raft setting when printing.
- Before using the toolhead, remove any filament leftovers remaining in the extruder.
- Prepare two plastic filaments that you want to print with. Make sure their endings are sharp, so they enter the extruder easily. Insert BOTH plastics to left and right filament slots, even if you plan to use only one of them. Also, make sure the printing temperature of both filaments is the same when using Dual PRO toolhead.
- You can use "flush nozzles" (ZMorph 2.0 S) or "feed both" (ZMorph 2.0 SX) to feed both materials at the same time.
Setting up your printer
- Select the toolhead in the LCD menu (Dual Head Extruder or Dual PRO extruder).
- When homing Dual Head extruder, always choose Home To Center option first.
Preparing the Voxelizer software
- Connect your PC/Mac to the ZMorph machine.
- Heat up left and right hot ends to recommended temperatures (depending on the material). If you are using Dual PRO toolhead, there is only one nozzle, so there is no need to heat both - only left one.
- Feed the left material carefully until if flows through the nozzle. Help it with your hand if necessary. Repeat this step with the right material.
- Make sure BOTH left and right filaments are in the extruder. Even when printing with only one material, both filaments should be in – this assures correct pressure in the feeding mechanism.
Once you have both materials loaded and the hot ends are ready, it’s the time to process the print in Voxelizer and generate G-codes.
- Load and voxelize the model (from STL or DICOM files).
- In Voxel View tab choose Dual Head preset or Dual PRO 1.75.
- Click Generate Gcode.
Usually, the file will be generated so that LEFT hot-end would print the model itself, and the RIGHT hot-end would print the support material. You can also use other combinations. In general, you can assign one or the other to print:
- Model outlines (shell)
- Model infill
- Support material
This is done in the advanced printing settings. Tick "object selection mode" box and click Left Mouse Button on a feature you would like to change. Then click Right Mouse Button, choose "set extruder" field and change it to either extruder 0 or extruder 1.
How to change object material
After voxelizing multiple objects, simply right-click on one of them, and select extruder that should print it. Once you do that, the program will switch to another filament in the right moment, creating multi-material prints.
Please note that models printed with different plastics CAN be very close to each other, or even touch. If you use models that are adjacent to each other, different plastics will fuse together, creating one, multi-colour, solid model.
Once the G-code is generated, it is recommended to copy it to a micro SD card. Start 3D printing by using Gcode Management toolbox or use the LCD panel on the machine.
- If you have PVA material, use it for support, so you then can dissolve it in water. Print slowly!
- If you have HIPS material, use it for support, that you then can dissolve it in d-limonene.
- Before you start printing, make sure that both nozzles are filled with plastic (choose Park Extruder option and then Flush Nozzles).
- Use T0/T1 buttons in Voxelizer to switch between active toolheads. Otherwise, use panel and Extrude E / Extrude Q options.
- When using Dual PRO toolhead, make sure to set an appropriate amount of artifact filament in Voxel Editor > Advanced > Project sub menu. A too low value will result in mixed filaments in your print.
Good luck with your prints! If you have any questions – let us know by writing to our support team.
Using dissolvable filament
If you want to get rid of a support material easily, it’s worth giving a try with PVA. It’s a bit harder in some cases, as it doesn’t stick to the printing surface and other plastics too well – but once this is harnessed, it gives some great results.
