How to ensure dimensional accuracy of FDM 3D printed PEEK parts?

While FDM 3D printing, complications may occur when processing large-size elements, such as the two-piece 40 cm model shown in the photo above, which, in addition to restrictive dimensional parameters, required the clearance along the entire element to be maintained while maintaining high strength parameters.
Dimensional accuracy depends not only on the technology in which we produce a given 3D print but also on materials out of which we build our element. Polymer’s technical parameters define the mechanical features of the given printout. We can’t forget about the importance of additional parameters, such as printer calibration, the type of used filament, and finally, the ambient temperature conditions.

Regarding heat and chemical resistance, the PEEK (Polyether Ether Ketone) polymer, as one of […]

Soluble support material for PEEK – Why it matters.

Demographic changes and industry development generate increased demand and material consumption as well as the need to automate production. In this field, modern polymers – such as PEEK, support optimization, and in some cases replace the materials used so far.
The improvement in the use of plastics in the industry, which we can observe, increases the requirements for the measurement correctness and quality management. Valued in industrial applications – PEEK – is an excellent example of the benefits of innovation in the field of polymers, on the other hand, it is also an excellent example to illustrate the technological requirements that one must meet to make production reasonable.
PEEK, a high-performance, temperature-resistant semi-crystalline polymer is often used as a replacement for metals in […]

How does moisture affect 3D printing fiber?

All filaments for 3D printing FDM / FFF are hygroscopic, i.e., they absorb moisture from the environment in which they are located.
Hygroscopicity is an undesirable effect in filaments for 3D printing. Plastic polymers consist of chains of molecules joined together. The absorbed water molecules destroy these chains, destroying the plastic and causing many problems when printing.

Don’t worry, the “wet” filament spools can be quickly dried, and proper storage can prevent future accidents.
Below, we look at how to recognize a wet filament, how to dry it, and finally how to store it correctly.

VSHAPER PRO printhead assembly.

The VSHAPER printhead mounting system with neodymium magnets guarantees a quick replacement and secure fixing.
ADVANTAGES:

Easy assembly/disassembly;
Stable, secure mounting of the printhead;
Easy positioning of the printhead during assembly;
Smooth and quick transition from high-temperature to low-temperature printing;
Time-saving when installing/removing the printhead;
Reduction of user interference;
Smooth transition of work with different nozzle diameters.

Efficient and quick replacement of the head in the VSHAPER PRO printer is possible thanks to the use of a new head mounting system using neodymium magnets. This solution guarantees the achievement of both a secure print module attachment and an easy replacement.

The use of a new printing module assembly solution shortens the time for replacing the extruder and reduces the user’s interference, thus […]
