The key

to higher productivity
The Spectra L allows for mass production of parts by offering the unique EB-LPB feature to tightly stack parts without compromising on quality. Electron Beam Powder Bed Fusion (EB-PBF) technology provides you with design freedom and allows you to build free-floating parts in semi-sintered powder. Any supports are primarily used for heat equalization and are easily removed when the build is finished.

Spectra L's improved melt process results in enhanced surface finish and consistent material properties for thin and bulky geometries. This provides the freedom to design parts without limiting your imagination. In addition, the Spectra L offers the largest build volume of our EB-LPB machines, allowing enhanced capacity to produce high-integrity parts, larger and faster than ever before.

    Point Melt technology

    Point Melt, available on Colibrium Additive's Spectra EB-LPB printers, is a process during which metal powder is melted through small "points" instead of lines as commonly done. This technology enables a more accurate temperature and reduces temperature gradients through the printing of a part. As result, metal parts produced using Point Melt can benefit from elimination of supports needed to build overhangs and an improved surface quality. Point Melt also enables additional scan strategies such as multiple passes on the same area allowing melt pool control and the resulting microstructure.
