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
Advantages	Material can be applied to existing structures High degree of development High reproducibility	Wide variety of materials possible, materials can be processed that are also not weldable Component properties comparable to MIM components Highest ratio of the volume of all printed parts to printer volume (even stacking is possible)
Disadvantages	Rough surfaces High thermal stresses are introduced into the components as a result of the process Support structures are required for complex geometries Surface porosity Reworking of components required, removal of support structures always necessary High heat input Powder handling	Sintering distortion of the components possible More complex process chain compared to direct AM methods

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 GERO 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.
