The micropores of the 3D printed parts are sealed by osmotic hardening to enhance the sealing performance. This may be an effective way that most people can't think of.
3D printing is essential for the prototyping of individualized components and components with complex geometries, and the use of additive technologies in the manufacture of end products is also rapidly increasing. The 3D printing process is the creation of three-dimensional objects layer by layer from different materials using a physical or chemical hardening and melting process, which often results in microporous structures. By their nature, they do not seal well and are therefore susceptible to water absorption, ageing, abrasion, UV radiation and other harmful influences.

The relevant person in charge of DIAMANT in Germany found Antarctic Bear and said, "We have a product that can empower the 3D printing industry. Antarctic Bear can tell the industry that it can solve major application problems."
DIAMANT has decades of research in the field of polymers and provides a wide range of customized functional casting compound solutions for 3D printing. For example, for ultra-light, highly stable casting compounds with a weight of less than 0.4 g/cm3, or for extremely heavy casting compounds with a density of up to 4 g/cm3, enabling casting compounds with additional functions, such as conductive or insulating, magnetic or non-magnetic , waterproof or absorbent.
3D printing parts want to reduce the effects of water absorption, aging, wear, and ultraviolet radiation. Traditional methods can only provide limited protection. It is reported that Germany DIAMANT has launched a completely different solution DIAMANT dichtol for this application:
penetration
seal
Dipping
Functional Casting Compounds
Wear-resistant coating

DIAMANT dichtol is an advanced ready-to-use polymer infiltration product for the repair and rapid sealing of pores, pores and cracks in rapid prototyping, 3D printing and additive manufacturing. Dichtol seals by capillary penetration, and the impregnated component, in addition to sealing the surface, effectively penetrates into the interior of the workpiece and hardens.
The composition of the high-performance polymers is very stable even under changing temperatures, ensuring a reliable seal. Dichtol is removed after processing or after a short working period. DIAMANT's dichtol can also improve the basic properties of workpieces, such as strength and stability of brittle materials.

DIAMANT's dichtol range of products are extremely resistant to physical, chemical and thermal stress. The inherent properties of the material are preserved. DIAMANT dichtol offers solutions for rapid prototyping (functional prototypes), rapid manufacturing (functional assemblies) and rapid tooling (tools and molds). After dichtol infiltration treatment, the process flow can be greatly shortened and raw materials can be saved.
Advantages of Dichtol products:
Efficient use of materials and easy application without special tools and machines
Seals gases and liquids inside and out
Complete sealing even of thin-walled components
Improves UV resistance of components
Sustainable improvement of surfaces: adjustable friction and surface finish.
Effectively prevent bacterial invasion
smooth surface structure
Effectively improve coating (spray) performance
Enhances component strength and stability
The surface is washable and meets drinking water and food safety standards.
