Direct and indirect Process Overview: Additive Manufacturing processes
Additive methods can be divided into two categories. Direct methods, such as SLM and EBM, are very well known and have reached a broad market acceptance in the industrial environment.
However, indirect methods have become more important in recent years. With these methods a green part is produced in the first process step, which is debinded and sintered in the second step.
| Direct AM Methods | Indirect AM Methods | |
|---|---|---|
| Method | L-PBF, EBM One-step process Direct production of components through welding processes |
BJ, CMF, M-FDM
Two-step process In the first step: Production of green parts
In the second step: Debinding and sintering of the green parts |

Furnaces & Ovens for direct additive methods
In direct additive processes high thermal stress is often generated by high heat input during the printing process. Carbolite provides customers with two suitable furnaces to achieve the best possible component properties.
GPCMA - Modified Atmosphere Furnace
The GPCMA modified atmosphere chamber furnaces are equipped with a metallic retort to provide a heated volume with a controlled atmosphere. They are floorstanding models with a smooth action hinged door arrangement.
Available with a range of maximum temperature from 1000 °C to 1150 °C depending on the selected retort material. Retort working volumes range from 37 to 245 litres.
Oxygen levels can be reduced to 30 ppm depending on the application. Perfect for stress relieving additive manufactured components particularly those produced via DMLS. This range of furnaces can be optionally specified for compliance to AMS2750F Nadcap class 1 for aerospace applications.

Heat Treating Powder Injection Molded & Additive Manufactured Parts
CARBOLITE GERO offers suitable furnaces for the various process steps in powder injection molding and additive manufacturing of metal and ceramic parts, such as thermal or catalytic debinding, drying of parts e. g. after solvent debinding, stress relieving, as well as sintering under protective gas, hydrogen or vacuum. Additive Manufacturing (AM) involving metals can be divided into direct and indirect processes. CARBOLITE GERO has purposely designed their product ranges to the highest specifications; with the GPCMA for direct, and the HTK for indirect 3D Additive Manufacturing and Powder Injection Molding (PIM) processes. These are just two products from the comprehensive additive manufacturing portfolio offered by CARBOLITE GERO.
Heat Treating 3D Additive Manufactured Parts
At present, there are two main techniques used in the additive manufacturing of 3D metal parts, Electron Beam Manufacturing (EBM) and Direct Metal Laser Sintering (DMLS). These take time but are outstanding for creating complex or ‘impossible’ parts which cannot be created using traditional casting or machining methodologies. This has already resulted in the creation of a multitude of prototype pieces as well as countless ‘impossible parts’ for the aerospace, automotive, tooling and medical sectors.
