Carbolite Gero Sintering Furnaces for Additive Manufacturing
Carbolite Gero is one of the world’s leading manufacturers of laboratory furnaces, industrial furnaces, and high-temperature furnaces for demanding heat treatment processes. Companies, research institutions, and industrial manufacturing facilities rely on Carbolite Gero’s furnace technologies for applications such as sintering, debinding, heat treatment, and additive manufacturing. The systems cover temperature ranges from 30 °C to 3000 °C and are suitable for metal, ceramic, and powder materials.
In the field of additive manufacturing, the thermal process is critical to the quality of the components. Specialized Carbolite Gero sintering furnaces are used, particularly in sinter-based additive manufacturing processes such as binder jetting. The systems enable:
- Thermal debinding
- Sintering under inert gas or vacuum
- Controlled process atmospheres
- Reproducible temperature profiles
HTK 8
The metallic HTK series from Carbolite includes high-temperature furnaces with heaters made of tungsten (HTK W) or molybdenum (HTK MO) and reach up to 2200 °C. Available in four sizes (8-120 l), they are suitable for laboratories, pilot plants and production. The front door facilitates loading and unloading. The metal construction ensures high purity of the inert gas atmosphere and vacuum. A high vacuum upgrade is available as an option. Frequently used gases are nitrogen, argon and hydrogen. A retort can be used for gas flow and temperature uniformity.
AAF
The AAF ashing ovens are designed for the complete ashing of samples at up to 1100 °C. With a programmable controller, efficient air flow (4-5 air changes/minute) and heating elements on four sides, they offer optimum temperature distribution. They comply with ISO 1171:2010, ASTM D3174-04 and ASTM D4422 - ideal for food, plastics, coal, etc. The robust ceramic muffle reliably protects the heating elements.
HTF 18
The HTF chamber furnace range from Carbolite offers precise heat treatment up to 1800 °C for applications such as sintering, annealing and calcination. It offers uniform temperature distribution, high energy efficiency and user-friendly control - ideal for research, quality control and production in areas such as ceramics, metallurgy and materials science.
FAQs - Frequently Asked Questions About Carbolite Gero
Why are Carbolite Gero sintering furnaces suitable for additive manufacturing?
Carbolite Gero offers a range of furnace systems suitable for sinter-based additive manufacturing processes such as metal binder jetting. These systems enable precise temperature profiles, controlled inert gas atmospheres, and reproducible sintering processes.
Which Carbolite Gero high-temperature furnace is suitable for binder jetting?
Carbolite Gero’s HTK systems are frequently used for binder jetting applications. The HTK 8 and HTK 25, in particular, are well-suited for research, development, and small-batch production in the field of metal and ceramic sintering.
What should you look for when buying a sintering furnace?
If you are looking to purchase a sintering furnace, the following factors are particularly important:
- Maximum temperature
- Process atmosphere
- Temperature uniformity
- Useful volume
- Material compatibility
- Vacuum capability
- Hydrogen operation
- Process reliability
Carbolite Gero high-temperature furnaces offer flexible solutions for research and industrial manufacturing.
Which Carbolite Gero ovens are suitable for micro 3D printing?
Step 1 – Thermal debinding in the AAF
Immediately after the printing process, the ceramic component is not yet a finished part—it still contains the polymer binder matrix, which serves as a carrier for the ceramic powder during the PµSL process. In the AAF, this matrix is thermally decomposed: at temperatures between 400 °C and 1100 °C, the binder undergoes complete oxidative combustion. Four air changes per minute ensure that the resulting combustion gases are reliably vented. The furnace’s four-sided heating ensures that no local temperature spikes occur—a critical factor for components with delicate microstructures in the micrometer range.
Step 2 – Sintering in HTF 18
After debinding, the result is a porous ceramic blank that does not yet possess any mechanical strength. Only sintering transforms it into a dense, load-bearing component. Alumina achieves its optimal density at process temperatures of 1500–1650 °C—a range that the HTF 18, with its MoSi₂ heating elements, replicates precisely and reproducibly. Custom heating rates, defined hold times, and controlled cooling phases can be freely programmed and tailored to the specific material and the desired component properties.
