The adhesion between the raft and the print bed is significantly influenced by the Z-offset. If the Z-offset is too low at the start of printing, the filament is pressed too hard onto the print bed, resulting in excessive adhesion between the Raft and the print bed. In this case, you can try to scrape …
Why does the Raft adhere too strongly to the print bed? Read More »
The adhesion between the support, model and print bed depends on several factors. If the nozzle and/or bed temperature is too low, the print speed in the interface is too high or the Z-offset is too large, the adhesion can become too weak, resulting in detachment between the support, model and/or print bed. Especially on …

Our recommended min. temperature to dissolve VXL 90 might already be too much for some PLA materials. You are safe to dissolve it at 40 °C, which will increase the dissolution time. To optimize dissolution time, you need to find out which max. temperature your PLA can withstand.
We recommend to dry VXL 70 at 50 °C, VXL 90 at 70 °C, VXL 111 at 90 °C and VXL 130 at 100 °C in an oven (preferably with vacuum), in each case for 4 hours.
During 3D printing, soft filament, such as VXL 70, can wrap around the drive gears because it tends to get caught between the teeth of the drive gears due to its flexibility. This risk exists in particular if the filament is not optimally guided through the extruder or the tension is not set correctly. It …
VXL 70 wraps around the drive gears. What can I do? Read More »
Translucent filaments, such as VXL, can be problematic for 3D printers with optical filament sensors because the light from the sensor may penetrate the translucent material. Hence, the sensor might not reliably detect the filament and the printing process will be interrupted incorrectly. In this case, the filament sensor should be deactivated.
During extended print jobs, especially in enclosed build chambers, with active build chamber heating or high print bed temperatures, discoloration of the support material may occur. This results from the influence of the elevated ambient temperature on the chemical properties of the material. However, the functionality is not compromised during the printing process. It is …
During long prints, VXL 111 and VXL 130 turn brown. Does this affect print quality? Read More »
If the Z-offset is not correctly set on a 3D printer with two print heads, it can lead to problems because the two nozzles may not have the correct distance to the print surface. In practice, this means that one nozzle may be too close to the surface while the other is too far away. …

VXL 70 and VXL 90 are comparatively soft materials. If the feeder tension is not ideally set, it can lead to abrasion on the drive gears over time, which can get stuck between the teeth. Consequently, the drive gears may no longer grip and feed the filament properly. It may appear as if there is …
