SLM (Selective laser melting)

How does SLM Metal 3D printing work?

How does SLM metal 3D printing work?

SLM technology is a technology that pre lays the powder and then uses laser rapid melting and rapid cooling to solidify it into shape. During the manufacturing process, it is necessary to use a powder spreader to evenly lay a layer of powder on the substrate in a sealed box, and then use a high-power laser beam to sinter the powder to complete the processing of the layer. Finally, the purpose of manufacturing the sample is achieved by repeating the process and accumulating the number of processing layers.

SLM Working Principle  

 

Advantages of SLM metal 3D printing:

SLM process is highly beneficial for those who need to produce their metal parts for prototyping and simulation, or for low-volume production by eliminating time-consuming tooling.

● Small batches directly produce

Directly driven by 3D design models to produce terminal metal products, eliminating intermediate transition links and saving time for mold opening and manufacturing;

● SLM is suitable for forming various complex shaped workpieces

such as parts with complex internal cavity structures and personalized needs in the medical field, which cannot be manufactured using traditional methods.

● Design verification and functional verification during for product development. 

RP technology can quickly convert CAD models of product design into physical fast models, thereby identifying design defects and improving product design. To shorten the research and development cycle and save costs

● Assembly verification.

such as the manufacturability and assembly of satellites, missiles, etc., shall be designed and inspected by RP method. This will greatly reduce the difficulty of designing and manufacturing such systems.

What materials can you choose for SLM prototype 3D printing?

Parts Structure Requirements for SLM 3D printing:

If you are new to metal 3D printing technology, please note the following content:

(1) Tapping is recommended for threads, and don't direct printing (including internal and external threads) ;

(2) Wall thickness at least 0.5MM, or it can't be guaranteed to print out

(3) Assembly parts need to be reminded and send assembly drawings.  If there is no reminder, we won't assemble them. The gap position should be left each side by 0.15mm;

(4) For parts with high assembly requirements (such as bearing holes/diameters/flat assembly positions), machining allowance should be reserved in advance, and then matched through secondary precision machining;

Surface treatment for 3D printed metal parts:

● Remove support              ● Polished                    ● Painting           ● Electroplate

● Water transfer printing    ● Sandblasting             ● Silk screen       ● Laser carving
