You navigate additive manufacturing's evolution with each production run. Material behavior, surface finish, and part integrity shape your results. These factors impact your lead times and your client's bottom line.
You may already rely on SLS for precision and reliability. But Multi Jet Fusion is changing the way teams approach throughput. Both methods fuse powdered material, yet they operate on distinct principles.
This is not just a material or hardware decision. You need a process that meets demand, scales production, and holds tolerances. Your manufacturing future could depend on choosing the right one.
SLS 3D Printing
Selective Laser Sintering, or SLS, is a powder-based 3D printing process. It uses a high-powered laser to fuse nylon or polymer powders. The laser scans each layer and bonds particles without needing support structures.
You benefit from excellent material strength and design freedom. Complex geometries, internal channels, and working hinges print easily. SLS works well for both prototypes and functional end-use parts.
Many industries rely on SLS for its mechanical performance. Automotive, aerospace, and healthcare sectors use it for durable, heat-resistant components. It supports medium-scale production with consistent part quality.
SLS 3D Printing Process
The printer spreads powder and fuses it with a laser. It repeats this layer by layer until the part is finished. Here are the common steps involved in SLS 3D printing;
First, you have to upload your 3D design to slicing software. The software divides the model into very thin horizontal layers. You also position and orient the part within the build space.
Then, you feed the nylon or polymer powder into the printer. The machine uses a thin and consistent coating of powder on the build platform. It also heats the chamber to a little lower than the melting point of the material.
The laser starts scanning the initial layer of the design you have. It melts the powder in the area where the component is to be formed. Then the printer applies a fresh layer of powder after every layer.
Part by part, the part is built up in the powder bed. The unfused powder would strengthen the structure, thus you do not require any additional supports. This procedure requires several hours on the basis of size.
After printing, the machine takes a long time to cool. Before you remove anything, you have to wait to prevent warping. It may take a number of additional hours to cool down.
You remove the printout from the printer and shake off the loose powder. The powder that is not used can be recycled to be used in the next job. The parts can also be completed by blasting or dyeing, in case that is required.

MJF 3D Printing
Multi Jet Fusion, or MJF, is an advanced 3D printing process. It uses a printing head to apply a special agent to powder layers. Then, an energy source fuses the powder exactly where the agent was applied.
You get parts with fine details and smooth surfaces. MJF works faster than many other powder-based methods. It also produces strong, functional parts ready for industrial use.
Many industries adopt MJF for rapid prototyping and production. You benefit from consistent quality, cost efficiency, and the ability to print complex geometries.
MJF 3D Printing Process
Multi Jet Fusion uses a unique process to build parts layer by layer. You start with a thin layer of powder spread evenly across the build area. Then, the printer deposits a special fusing agent where you want the material to solidify. An infrared light passes over the surface, fusing the powder only where the agent is applied. This process repeats, building your part one layer at a time with great speed and precision.
The first step is sprinkling a thin amount of nylon powder. The roller makes the layer smooth and irregular. This is a consistent background that is essential to part precision.
The fusing agent that jets onto the powder is through the print head. It indicates the regions that will become solid in this layer. Defining edges and enhancing resolution is done by the use of a detailing agent.
The powder bed is covered with an infrared lamp. It melts and fuses only the surfaces that are coated with the fusing agent. It is a selective heating that solidifies your part layer purely.
The same is repeated with each layer. The new powder layer is then spread after fusion. The section slowly increases within the powder bed.
After printing, the chamber cools off gradually. You take out your portion of loose powder and clean it well. Such post-treatments as dyeing or smoothing may be used to improve looks and performance.
Functional MJF 3D Printed Part
Multi Jet Fusion offers speed and precision in one package. You get parts with fine details and strong mechanical properties. This process suits both prototyping and functional manufacturing.
MJF prints layers fast through an effective fusing technique. You shorten lead times as opposed to most other 3D printing technologies. Quicker printing can help you speed up your development phases.
The printer gives you smooth features and sharp surfaces. The detailing agent that is used in MJF enhances the edges and minimizes post-processing. This implies that you will do less finishing.
MJF parts have great mechanical properties with consistency. You have functional pieces that would resist strain and stress. This renders MJF applicable in tough applications.
You are able to print complex geometries, internal channels, and assemblies during a single build. MJF helps complex structures without any support structures. This broadens your design options to a great extent.
The traditional MJF prints have a recyclable and reusable powdered material in unused products. This decreases wastage and reduces the cost of material. You also save money and minimize the use of the environment.
MJF also backs the idea of printing more parts at once. This renders batch production cost-effective. You are able to increase your manufacturing without transforming your process.
MJF printers have a close grip on the printing conditions. You are ensured of the same quality even after several builds. This consistency provides expected repeat performance of parts.
