Removing the Support

Before any attempt to remove the support structure, wear safety gloves and safety 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 print (e.g. hanging material strands), the SUPPORT settings are inadequate. 

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

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

Types of Infill

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 high infill option. But if you want to increase the model’s durability, set a higher type of infill.
Maximum infill allows printing with the highest strength level. But the larger infill, the more time and material is needed for such a print.
Z-SUITE gives an opportunity to set infill 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 it was designed. 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

Large Prints

The problem of warping is frequent with large prints. Bigger models often shrink and that’s why they do not stick to the platform while printing.

Make sure that the platform is calibrated and the printer is not exposed to the draft. 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 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 ABS juice on the surface so that the model won’t come off the platform. Fan cooler should be set to 0.

Printing Small Objects

Printing Small Objects

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

Set the lowest possible layer thickness and the additional FAN SPEED to 80-100%. Also, print two or more models simultaneously so that the layers have time to cool down (and you will save the printing material at the same time).

Placing your model vertically is also profitable in this case.

Printing with Z-PLA Pro

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 the majority of 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 is dedicated for this particular material only. The hotend should be new and not used with other materials or 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

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

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

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,
  • take off 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 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 hotend V2. Do not use hotend V1.

Printing Materials Storage Tips

Printing Materials Storage Tips

It is really important to take good care of the printing material while storing unused spools. Providing proper storage conditions is essential in order to prevent having a failed print since the quality of the material highly influences the final look of the model.

First of all, once you finish the printing process, unload the material and take the spool off of the spool holder, secure the end of the material as it is shown in the picture to avoid having tangled threads of material on the spool. The holes in the spool have been designed especially for this purpose.

What’s more, keep the spool at room temperature and avoid sunlight and humidity. Preferably, use vacuum-packaing while storing spools.
