Modern 3D printing technology is revolutionizing the way we design, create, and implement new products. Thanks to additive manufacturing, rapid prototyping is possible, as well as the production of ready-to-use parts with complex geometries that would be expensive or even impossible to produce using traditional methods.
The use of 3D printing in prototyping allows for shorter time-to-market, lower unit production costs, and design freedom that was previously unattainable. 3D prints are used across many industries – from medicine, automotive, and public transport to defense, architecture, and industrial design. At Fibometry, we offer comprehensive services – from support in designing models for 3D printing, through material selection, to the final 3D print using technologies such as MJF, SLS, SLA, PJ, FDM and DMLS. We work with both individual clients and companies looking to turn their ideas into reality.
Special attention should be given to powder-based 3D printing technologies – MJF (Multi Jet Fusion) and SLS (Selective Laser Sintering). Both fall under polyamide powder printing but differ in terms of precision and application.
MJF technology is gaining popularity as an efficient, precise, and fast alternative to the more traditional SLS method. While both have their advantages, MJF often prevails where high detail quality, production speed, and repeatability in small batches are critical.
MJF vs SLS technology
Material fusing method
MJF uses a head with a precision-applied bonding agent, in layers 0.8 mm thick, which is sintered under heat.
SLS uses a laser to selectively sinter powder layer by layer at 0.06-0.18 mm thickness.
Accuracy and print quality
MJF offers high (and superior) resolution and dimensional accuracy due to thinner layers and even distribution of the binding agent. The MJF can print a model with a minimum wall thickness as low as 0.5- 0.7 mm in some cases.
SLS can print a model with a minimum wall thickness of 0.8 mm and may struggle to achieve smooth surfaces and sharp details, especially in complex geometries.
Printing speed
MJF stands out with faster production times, as each layer is formed simultaneously, unlike laser-based point-by-point fusion in SLS.
SLS takes more time to complete each layer, which increases the total printing time, especially for larger parts.
Repeatability and mechanical properties
MJF offers better repeatability and more consistent mechanical properties across the entire model, making it ideal for low-volume production.
SLS also produces durable parts, but variations in internal structure can be more noticeable between prints.
Surface
MJF typically prints models with a uniform matt surface, ready for further processing or use without additional processes.
SLS also prints models with a surface ready for use without additional processes but can also be subjected to further finishing processes.
Key advantages of MJF over SLS:
- Faster project turnaround, significantly shortening the path from concept to final product
- Higher dimensional accuracy and repeatability
- Superior mechanical properties of printed parts
- Consistent surface finish without the need for extra processing
3D prototyping using Multi Jet Fusion is the future – and it’s available today!
