What is PBF technology?

Powder Bed Fusion (PBF) technology is a metal additive manufacturing process that allows the production of high-precision parts with very high mechanical properties.

In a laser PBF machine, parts are made in successive horizontal layers. For each layer, metal powder is spread on a production platform, and a laser melts the areas that need to be solidified.

FormUp 350 machines are safe, efficient and scalable. They integrate more than ten years of experience of AddUp and Michelin in PBF technology.

Our PBF solutions : the best compromise between quality and productivity

FormUp machine offers a build volume of 350x350x350 mm, up to 4 lasers with 3D optical scanners ensuring a homogeneous laser beam on 100% of the platform surface.

Additive technologies from SBI

1. Additive technologies, overview

add). Installations that use these technologies are also called 3D printers.

These technologies are the most promising technologies of the present and future. Layer-by-layer building up and synthesis of an object occurs with the help of 3D computer technologies and contributes to the production of many useful things for everyday life, human health and safety, for example, additive technologies in aircraft manufacturing help to create more highly economical and lighter air transport, while its aerodynamic properties are fully preserved. In 2009, this ASTM (American Society for Testing and Materials) process was classified as an AM technology (Table 1). photograph

Table 1: Classification of AM-processes

The main technically feasible methods of manufacturing metal products are Powder Bed Fusion (PBF ) and Directed Energy Deposition ( DED 901).

While the PBF process can produce small and complex geometries, the DED build-up processes can produce large-sized parts with high productivity and speed.

Powder or wire can be used as a material for DED build-up process, for metal melting it is used as a light arc between the electrode and the workpiece, a laser beam or an electron beam electron beam.

A variation of the DED wire-fed build-up process is classified as Wire and Arc Additive Manufacturing or (WAAM) for short. This designation was introduced by Cranfield University and describes which wire and which energy source is used when building products using an electric arc.

At the disposal of the AM processes, various ways of building up products are offered. However, this does not mean that every possible solution is economical and efficient.

Products manufactured according to AM extension technology can be classified according to the degree of their complexity in the following graph (Fig. 1).

Large parts with a relatively simple design are made using the DED build-up process, small and complex products using the PBF build-up process

Figure 1. AM process and its scope

2. Why AM?


Today's requirements for the competitiveness of the company and the environmental friendliness of production are becoming more complex every day. Additive manufacturing provides a solution that meets both of these requirements. The so-called buy-to-fly-ratio (BTFR) indicates the ratio of raw materials to the finished component:

Where at the top of the fraction is the mass of the workpiece, and at the bottom is the mass of the finished product.

Some manufacturing methods, such as turning and milling, have a BTFR value of 5-50 or even higher, depending on the structural complexity of the part, i.e. a lot of material goes into chips (Figure 2).

Additive manufacturing can significantly reduce this ratio - depending on the degree of post-processing. A lower BTFR not only saves raw material costs, but also reduces the cost and time required to rework products.

Figure 2 Chips are the main material in the normal production of products

Another advantage offered by AM, is the rapid production of the required products. Especially in the case of expensive and rather rarely used materials in production, very long production times are a problem, AM solves these issues.

Using additive manufacturing, a product can be quickly produced on site and using materials readily available on the market.

3. PWD process: Plasma Wire Deposition

PWD process uses a wire-fed plasma arc to build up products and is classified Directed Energy Deposition DED and WAAM . The basis for this method is a plasma torch that produces a plasma arc, which transfers the wire introduced into it onto a prefabricated product substrate. When the metal is melted, one pass is created on the product, with a given number of passes, a product ready for processing is created.

Figure 3 shows a diagram of the PWD process with the introduction of the wire into the plasma arc and the formation of passes on the product.

Figure 3. PWD-process diagram

Plasma arc (PTA ) depending on the current source used, operates in two modes: (-) is supplied to the tungsten electrode of the plasma torch, and (+) to the product.

Straight polarity mode DCEN is used to build up various metals: steel, titanium, nickel base alloys.

AC mode - for building aluminium.

The ability to change the operating mode allows you to select the correct production mode. In addition, DC modes can be pulsed for better control of heat input. The pulse frequency can be set from 1 Hz to 2000 Hz.

PTA Advantage is the ability to start a plasma arc without adding wire. This allows you to create process parameters such as preheating the base before welding and the workpiece itself.

Unlike other DED power sources, the plasma torch generates a high pressure plasma that presses the weld pool in the opposite direction of the torch travel. This property allows you to accurately complete the surfacing of the layer in the manufacture of a non-circular part of the product.


Figure 2 :

layer pattern Figure 2 shows the layer pattern. Because the plasma "presses" the weld pool in the opposite direction (1), the end edge is not straight (2). When welding in the opposite direction, the weld pool is pressed against the end edge (3) and a smooth edge is formed.

PWD is not prone to forming a layer of "humps" on the surface.

For higher deposition rates, welding with hot wire . Heating of the welding wire is achieved by creating a chain between the workpiece and the wire. When the wire touches the workpiece, it is heated by the resistance and reduces the energy consumption of the plasma to melt the wire. In this way, higher wire feed speeds are possible and a higher deposition rate is achieved.

Figure 3 : Higher deposition rates with hot wire

Materials and welding options

Since the AT -system works with PTA, the materials used - the raw material (in the form of wire) and the base - must be conductive. All materials that can be welded with PTA can be produced with our AT system. Table 2 shows all preferred combinations of PTA modes with known materials.

Table 2 : Possible Weld Modes and Material Combinations

The AT system can use a multiple wire feeder (MWF), which means it feeds multiple wires into the PTA. MWF provides lower wire feed speeds, which makes the printing process even more stable.

Figure 4 : Wire feeder and plasma torch AT system

Deposition rate

One of the main advantages of PWD is its high deposition rate compared to other AT processes.

During our testing, we achieved deposition rates of 4-10 kg/h depending on the materials used and the set of welding parameters used. However, the potential limit is much higher and we are constantly finding new parameters to achieve higher deposition rates.

4. Diagram of 3D printer

The 3D printer (Figure 5) consists of a 6 axis CNC setup.

- 4 axes for moving the plasma torch (X, Y, Z axes, rotation along its C axis)

- 2 axes of the turntable (A, B)

fig 5 the axial design of the plant allows the production of cylindrical, spherical, conical and general three-dimensional objects (fig. 6)

The maximum size of the products is 800x600 mm with a maximum weight of 500 kg. A 2400x1200 mm clamping table can be installed instead of the tilt-rotator. This allows you to implement products with a size of 2000x600x600 mm, weighing up to 2000 kg.

Since 3D build-up places the highest demands on the product being produced, a protective gas atmosphere must be maintained around it throughout the entire printing process.

The unit is designed to keep the gas filling time as fast as possible and in a sufficiently small volume, which in turn shortens the purge time and saves inert gas.

fig 6 example of grown products

The entire process of growing a product is controlled and recorded by a video camera system and is linked to the parameters of the movement and the growing process recorded in the memory (for example, plasma current, plasma voltage, gas flow, etc.) This greatly simplifies, for example, the subsequent evaluation and optimization of the process.

Another condition for ensuring the quality of build-up is the control of the product geometry, where after each layer the object is scanned and its nominal geometry is compared with the actual geometry. By controlling the plasma parameters, defects such as pore formation can be detected and eliminated.

Figure 7 shows a 3D scan of the product showing the substrate and material structure (red coloration).

fig 7 3D scan product

In order to ensure, in an inert gas filled installation, a quick change of the substrate and wear consumables and spare parts, “hand gloves” are built into the 3D printer.

The whole process of extension movements is controlled by G-code and the movements that occur can be monitored during the movements via the human-machine interface.

fig 8 Axes on the 3D printer

Figure 9 shows the basic design of the 3D printer, the installation consists of a working area and a control cabinet. Thanks to its compact design (3200x2100x3200) and a total weight of up to 5000 kg, the unit can be placed in a container.

The unit's control cabinet consists of a controller cabinet, an inverter cabinet and a cooling circuit cabinet.

Fig. 9 Plant cabinet diagram

The cooling circuits of the units are connected to an external cooling source, which can be implemented either with a refrigeration unit on site or with a cooling network.

Side-mounted control panel for entering motion and plasma arc parameters when building up a work piece.

The frame of the unit is made of stainless steel, to which are attached the axes (X, Y, Z), rotary table, plasma torch and wire feeder.

The relatively small volume of the inert gas plant, approx. 10 m³, reduces the purge time as well as the inert gas consumption.

The software called Plasma Control Software (PCS) is developed by our programmers and can be used according to our customers' needs.

Materials and Jobs Used

AM uses Dual Wire Feeder (DWF), optional Multiwire Feeder (MWF). They provide a lower wire feed speed compared to single wire feed while maintaining the same productivity. In addition, DWF and MWF provide a more stable process and allow you to organize workpiece alloying. Doping can be local (zoning) or global. The following figure (10) shows alloying by adding two different types of wire.
