TIPS: What is the difference between DMLS/SLM/SLS?

DMLS (direct metal laser sintering), SLM (selective laser melting) and SLS (selective laser sintering) are all additive manufacturing technologies, also known as 3D printing technologies. They are similar in principle, but there are also many differences, which are explained in detail below:

DMLS (direct metal laser sintering)

Principle details: In the DMLS process, the laser beam is irradiated onto the metal powder bed, and its energy causes the metal powder particles to reach a temperature below their melting point. Although this temperature does not completely melt the powder, it can soften and bond the surface of the powder particles to a certain extent. It's like we put a handful of sand together and use a special method to make the sand particles stick together a little, but the sand itself does not become liquid and solidify. By repeating this process layer by layer, these slightly bonded powder layers are gradually piled up, and finally a three-dimensional metal part is formed. However, because the powder is not completely melted, there will be some tiny pores inside the part, just like a piece of bread with many small pores.
Material properties and applicable scenarios: The metal materials used in DMLS are usually those that can maintain certain strength and performance in this partially sintered state, such as stainless steel, titanium alloy, etc. After these materials have pores inside the parts after the DMLS process, they can still meet the requirements of many engineering applications, such as the manufacture of mechanical parts that do not require ultra-high strength but require complex shapes.

SLM (Selective Laser Melting)
Principle details: SLM is a bit like DMLS, but there is a key difference, that is, the laser energy used in SLM is higher, high enough to completely melt the metal powder. Imagine that we turned the metal powder into liquid, and then let the liquid cool and solidify quickly, so that a very dense metal structure is formed. Just like we heat a piece of metal until it is completely melted, and then pour it into a mold to cool and form it, but SLM uses lasers to melt the powder little by little, and then stacks it into parts layer by layer, instead of melting all the materials and pouring them into the mold at once. Because the powder is completely melted and then solidified, there are almost no pores inside the parts, the density is very high, and the performance is closer to the metal parts we make with traditional forging methods.
Material properties and applicable scenarios: SLM can process some metals with high reflectivity and high thermal conductivity, such as pure copper, because its high-energy laser can overcome the characteristics of these metals and allow them to be fully melted. Since the parts manufactured by SLM have high density and good performance, SLM is very suitable in some fields with extremely high requirements for part performance, such as engine blades in the aerospace field, which need to withstand high temperature, high pressure and high stress, and implants in the medical field, which require good biocompatibility and high strength.

To distinguish DMLS, SLM and SLS technologies, you can start from the following aspects:

Observe the material

SLS: It is usually used to process non-metallic powder materials, such as nylon, polypropylene, polystyrene and other polymer materials, and can also process ceramic powders, coated sand, etc. However, when processing metal materials, polymer materials are generally required to be mixed.

SLM: It mainly uses pre-alloyed metal powders, such as stainless steel, titanium alloy, nickel-based high-temperature alloy, etc., and has high requirements for the oxygen content, sphericity, and particle size distribution of the powder.
DMLS: The metal powders for molding are quite diverse, including single-component powders (such as Fe powder), multi-component powders (such as brass and tin mixed powders), and pre-alloyed powders.
Analysis of molding principle
SLS: For polymer materials or coated sand, the laser may only melt the polymer materials with lower melting points in the outer layer, so that the particles are bonded to each other, which belongs to the semi-molten state. Even SLS, which directly uses metal powder, adopts the liquid phase sintering mechanism. The powder material is partially melted during the molding process, and the powder particles retain their solid phase core, and the powder is densified through subsequent solid phase particle rearrangement and liquid phase solidification bonding.
SLM: The laser completely melts the metal powder, realizes metallurgical bonding and then solidifies rapidly, and the performance of the molded parts can reach the performance of parts made by traditional methods.
DMLS: Similar to SLM, in most cases, metal powder is completely melted. However, when the laser acts on multi-component powder, the low-melting-point metal is first melted to form a liquid phase, and the solid phase particles are rearranged. Finally, the particles are close to each other, in contact, and bonded.

View equipment structure
SLS: Powder is usually delivered by roller, because the powder needs to be compacted during the molding process, but the roller may have a powder sticking problem. The equipment generally uses a 10.6μm CO₂ laser.
SLM: The scraper powder delivery method is adopted, including metal scrapers, ceramic scrapers, and rubber scrapers. A 1.06μm fiber laser is used.
DMLS: Powder delivery methods include roller powder delivery and coaxial powder delivery. The main difference from SLM is coaxial powder delivery. Also using a 1.06μm fiber laser, the surface roughness of the molded part is large, and more subsequent treatment is required before it can be used.

Evaluate part performance and quality
SLS: Parts molded with polymer materials have good flexibility and impact resistance, but parts made of metal and ceramic materials have relatively weak performance, high porosity, low density, poor tensile strength, and high surface roughness.
SLM: The density of parts can be close to 100%, with excellent mechanical properties such as high strength, high hardness, good toughness and fatigue performance, and good surface quality, but there may still be some roughness and micro defects.
DMLS: The performance of parts is between SLM and SLS. Due to the possibility of partial sintering, its density is usually between 95%-99%, the surface is relatively rough, and there may be pores inside.
Understand molding speed and cost
SLS: The equipment cost is relatively low and the production efficiency is high, especially for polymer materials, because the melting point is low, the laser scanning speed can be faster, and the powder layer thickness can be appropriately increased.
SLM: The equipment cost is high, and the production efficiency is similar to DMLS, but in some cases, the molding speed may be slightly faster due to the higher scanning speed and larger layer thickness.
DMLS: The equipment cost is high and the production efficiency is relatively low, especially for large parts. The molding time is long due to the limitations of laser scanning speed and powder layer thickness.
