Removing the Support

Before any attempt to remove the support structure, wear safety gloves and glasses.

At first, detach the raft by hand.

Then, remove the support using the tools from the Starter Kit: a cutting knife, a scalpel or a pair of pliers or tweezers.

If any deformed elements start to appear on the model during the printing process (e.g. hanging strands of material), the SUPPORT settings are inadequate. 

To avoid those imperfections, increase the value of the SUPPORT ANGLE. Bear in mind that greater amount of support will be even more difficult to remove.

Another way to eliminate such effect is to increase the FAN SPEED.


Types of Infill

The infill is an option which determines the amount of material that will be printed within the walls of the model.
Most models do not require setting a high infill option. But if you want to increase the model’s durability, set a higher type of infill.
The maximum infill allows to print with the highest strength level. But the larger infill, the more time and material is needed for such a print.
The Z-SUITE allows to set the infill level according to your needs and plans for the model. The following photos show 6 types of infill.


Setting Proper Dimensions

Zortrax printing materials vary when it comes to their physical properties. The main thing you have to consider before the printing process is the level of shrinkage of a particular material. It can basically influence the actual size of the printed object. Usually the final object is smaller than the design. To avoid this, you have to estimate the approximate shrinkage and add from 0.2mm to 0.3mm to each dimension.

The minimum diameter of the hole must be 1mm. The minimum wall thickness is 0.8mm, whereas with the shell infill, the minimum wall thickness can be of 0.4mm.



Large Prints


The problem of warping is frequent with large prints. Bigger models often shrink and they do not stick to the platform during the printing process.

Make sure that the platform is calibrated and the printer is not exposed to drafts. Carry out Platform Maintenance and use side covers and platform V2 with your 3D printer.

Additionally, it is better to choose low density of infill (medium or light) or, if low density is problematic, choose the mesh option. For large prints with no precise details the optimum layer thickness is 0,19mm or 0,29mm.

Calibrate the platform properly and spread the Z-ABS juice on the surface so that the model won’t come off of the platform. The FAN SPEED should be set to 0.


Printing Small Objects

Very small objects require some additional options such as the appropriate FAN SPEED and LAYER THICKNESS settings.

Set the lowest layer thickness possible and the additional FAN SPEED to 80-100%. Also, print two or more models simultaneously so that the layers of each print have time to cool down.

Placing your model vertically is also profitable in this case.


Printing with Z-PLA Pro


Z-PLA Pro has been developed using natural and recyclable components. It is characterized by a very low shrinkage level, therefore, it is useful while 3D printing large-sized models covering most of the workspace in Zortrax devices.

However, in order to avoid problems while printing with Z-PLA Pro, it is advisable to use a separate hotend that will be dedicated only for printing with this material. The hotend should be new and not used with other materials during different projects.

Also, it is important to check the upper extruder fan for proper functioning. If the fan does not work correctly, replace it before starting to print with Z-PLA Pro.


Sharp Edges


It is important to avoid sharp edges in the design of your model. Sharp edges are the stress concentration points, so there is a risk of damaging your print.

Make sure to round off all edges and corners in the design of your model before printing so as to improve the model’s resistance. Rounded edges make the model less prone to deformation and help to release the tension.


Printing Movable Parts


While printing movable parts, it is importrant to keep proper spaces between particular parts. These spaces are responsible for the flexibility of your model. The minimum space requirement is 0.4mm for these kinds of prints.


Tips for Printing with Z-GLASS / Z-PETG


Z-GLASS and Z-PETG are heat sensitive materials, therefore it is possible that you may encounter problems with extrusion and/or the final look of your print may be imperfect.

To make printing with Z-GLASS or Z-PETG easier and problem-free:

  • keep proper printing conditions. The temperature should not exceed 28°C,
  • remove the side covers but only if the printer is not exposed to drafts.

Immediately after the print, unload Z-GLASS/Z-PETG from the extruder. These materials should not be left loaded as they become more difficult to extrude from the hotend after some time. In addition, once you finish printing with Z-GLASS/Z-PETG, print a small-sized object using Z-ABS to prevent further problems with extrusion.

If these steps do not help and you still have problems with extrusion, the nozzle or the hotend should be replaced.

Remember, printing with Z-GLASS and Z-PETG requires using the hotend V2. Do not use the hotend V1.
