Ceramics
Overview
AdmaPrint
The AdmaPrint feedstock is specially formulated with a mixture of photosensitive resins and a solid load of powder, called slurry. The use of light curing and slurries allows achieving high resolutions and very fine surface roughness in printed products. In addition, it prevents health hazards and (cross-)contamination related to the use of dry powders. The AdmaPrint feedstocks can be used to print complex geometries in ceramic and metal, large and fine structures and a wide variety of functional products.
Advanced ceramics for high-demanding applications
Al2O3 Alumina
Alumina (Al2O3) is one of the most commonly used ceramics in high-tech applications because of its wear resistance and its high chemical and temperature stability. Alumina finds applications in water purification, insulators, semiconductor components, and medical implants. The AdmaPrint A130, Admatec’s alumina recipe, delivers components with high relative density (> 99%) and smooth surfaces (Ra = 0.3-1.3 um) and can be printed and sintered in wallthicknesses up to 10 mm.
Properties
- High hardness
- High electrical resistance
- Refractoriness
Applications
- Semiconductors and electronics
- Medical implants
- Valves and pumps

ZrO2 Zirconia
With superior mechanical properties, zirconia (ZrO2) presents high flexural strength and fracture resistance. In addition, zirconia shows very low thermal conductivity, high chemical inertness, and biocompatibility. Among the applications of zirconia, we can find structural and wear resistant applications, aesthetical parts like jewelry and medical applications like dental restorations. The AdmaPrint Z130, Admatec’s zirconia recipe, delivers mechanically strong products with high definition.
Properties
- Low thermal conductivity
- High electrical resistance
- High toughness
Applications
- Extrusion dies
- Connectors
- Jewelry

Fused Silica
Silica (SiO2) is well known for its thermal shock resistance and leachability (chemical dissolution). For these reasons, it is commonly used as base material for the production of shells and cores in investment casting for aerospace and energy applications. The AdmaPrint S130, Admatec's silica-based recipe, delivers mechanically strong shells with excellent surface properties.
Properties
- High thermal shock resistance
- Chemical and mechanical leachability
- Gas permeability
Applications
- High precision casting
- Refractories
Hydroxyapatite
Hydroxyapatite is a naturally occurring mineral that makes up most of the bones and teeth. Hydroxyapatite is very well-suited to use as a precursor in biomedical applications such as bone replacement. Additive manufacturing brings the form freedom capabilities that allow the personalization of medical implants. Admatec produces the AdmaPrint B130 feedstocks that can generate porous yet strong products necessary in implantology. We use hydroxyapatite from CAM Bioceramics, which is an ISO 13485:2016 certified supplier of medical grade ceramic materials.
Properties
- Biocompatible
- Bioactive
- Osseointegation
Applications
- Orthopedic implants
- Spinal and Cranial implants
- Bone-substitutes
Custom-developed slurry on demand
and resin premix compositions for own material development
The Admaflex technology provides an open platform that allows the production of a multitude of materials. This allows the adaptation of the technique to customer-specific materials without having to modify the system.
We aim for continuous material improvement and development of new feedstocks for additive manufacturing of ceramics and metals. Our in-house R&D department is able to develop new compositions and materials on client demand, as well as carry on with continuous materials development. If you have an application or material that you would like to use in additive manufacturing, we can help you with your developments, by offering a slurry development R&D project.
If you have a trusted powder of your own or you didn’t find the material that you would like in our portfolio, you can contact us to launch a slurry development R&D project.
Alternatively, if you wish to do the material development in-house, Admatec can offer you, as Admaflex-machine-user, a proven resin premix composition for developing your own slurries, both with ceramics and metals.
