Additive Manufacturing - Machines and Processes

Additive manufacturing is an innovative manufacturing process in which 3D objects are built

The process begins with creating a digital 3D model of the desired object. This can be created using CAD data. Software divides the 3D model into a series of thin horizontal layers. The material used for printing, often metals in industry, is prepared as powder for the 3D printer. The 3D printer builds the object layer by layer. After each layer is completed, the material is cured or cooled according to its specific properties. The steps are repeated until the object is fully constructed.

Advantages of additive manufacturing

	Design freedom for complex structures
	Efficient consumption of material
	Individualized productions from 1 piece
	Variety of materials expands application options

	Weight reduction thanks to hollow components
	On-site production reduces transportation costs
	Cheaper than other manufacturing methods
	Faster production of innovative prototypes, components and tools

Weighing Systems and Equipment for Metal Powder Production in Additive Manufacturing

Additive manufacturing (AM) is the process of making objects by adding different materials: these process of using materials to make objects from 3D model data (source: Additive Manufacturing, 2021) is often referred to simply as 3D printing. Our machines and processes enable the use of metal powder for industrial additive manufacturing.

In additive manufacturing, process accuracy is crucial to achieve optimal flow properties of the powder. From the very beginning of the metal powder manufacturing process, weighing and feeding systems play a critical role in the quality of the additive manufacturing process, as it is a complex and in-depth manufacturing process that encompasses the entire printing workflow.

L.B. Bohle’s precision weighing and feeding systems for the production of metal powders enable optimal raw material management from the start of the production process and ensure a significant increase in product quality.

Metal Powder Blending
in Small and Large Quantities

The mixing of metal powders places high demands on the safety and quality of the 3D printing or additive manufacturing process.
When producing metal powders, the homogeneity of the mixture produced is critical. The aim of the mixing process is to achieve a uniform distribution of all components in the mixture.

Advantages of our Blenders for Metal Powder to the Additive Manufacturing

	Mixing elements integrated in the container lid ensure homogeneous, effective and, above all, machine-friendly mixing
	Double valve technology for dust-free operation
	Rotates up to 6 rpm
	Inertisation possible for preventing oxidation or explosive atmosphere

	Less machine wear / less machine load
	No tumbling and therefore no heavy “weight load” on the blender
	No high-speed mixing impeller in the abrasive metal powder as in an active mixer, instead the powder slides gently through our mixing baffles.

LM 40 - Mixing of Metal Powder in Small Quantities

The LM 40 is the optimal mixer for mixing metal powder for use in the 3D printer or within additive manufacturing. The blender is driven by a three-phase motor, which is in the machine housing. The control system of the machine is also located there.

Scale-Up
The LM 40 provides a secured scale-up

Advantages in additive manufacturing:

Results scalable to the desired production size
Fast, uncomplicated and completely discharged
Use of different containers and bins
High flexibility and mobility
LM 40 is mobile on wheels and can be used flexibly

Safe Storage of Metal Powders: Containers, Bins and IBCs

Containers and bins are used in additive manufacturing for mixing, storing and transporting metal powders. All containers are specifically designed to meet the needs of the industry. An advantage of L.B. Bohle’s bins and containers is that they are easy and complete to clean.

In the additive manufacturing of metal powders, our containers can be used as

	Mixing containers
	Storage containers
	Transport containers.

Lifting Columns HS – Safe Product Transport and Perfect Handling for the Production Process

Our goal is to make your additive manufacturing process safer. With our stationary and space-saving lifting columns, we guarantee a safe manufacturing process of metal powders.

The liftung columns are flexible in use and their space-saving design allows them to be installed in the tightest of production areas.

For years, L.B. Bohle has successfully used an electrically driven chain drive. Competitors’ lifting columns are usually equipped with hydraulic lifting technology. The L.B. Bohle drive requires significantly less maintenance, is more hygienic and sustainable, as no oil is used.
