Advancing polymer powder bed fusion (PBF) with
Direct Image Sintering (DIS)
Visitech has pioneered the development of Direct Image Sintering (DIS), a polymer powder bed fusion methodology that leverages our advanced IR projector in conjunction with scrolling technology to augment build size.
DIS boosts print speed, overcomes build size and packing density limits of traditional SLS for PBF, and does so at high resolution – while producing stronger parts.

Superb results for DIS
Test results produced by an independent lab found that the new Direct Image Sintering (DIS) technology not only prints parts faster than traditional SLS laser; printed parts are also stronger. Read how DIS widens the market potential for polymer powder bed fusion applications by enabling high precision, volume and speed, in 3Dprint.com’s article on the subject.
Maximum Throughput in Polymer Powder Bed Fusion
Polymer PBF using selective laser sintering (SLS) faces well-recognized challenges, especially regarding build speed and size. Although a single laser can incrementally expose and fuse the powder within a limited build area, SLS is not suitable for large-volume industrial uses.
A powerful IR projector, however, can fuse an entire powder layer in a single flash. Exposing a direct image onto the powder and fusing it in one step is the concept of direct image sintering.
Applying our scrolling DLP projector technology enables the projector – or a series of interconnected projectors – to move dynamically across the build field, directly exposing the image and sintering a far larger area. Our proprietary software seamlessly stitches images between projectors, eliminating size restrictions on the build area.
A typical DIS system comprises a single or multiple LUXBEAM Rapid System LRS MCx-WX-IR projectors and the proprietary LAMA software, depending on the builder’s desired configuration. To complete the system, machine builders provide their own choice of powder handling and heating setup, along with an X -Z motion system, into which DIS integrates.
Visitech supports quick, easy technology implementation for machine builders by providing reference and custom motion system configurations.
