Actually EBM is usually building parts in the range of 60 to 120 micron thick layers, while we build parts in DMLS EOS machines in 20 or 40 micron. Particles are smaller and you can clean small ducts from the non sintered power easyly (imagin a spiral 0.6 mm diameter conduit)<br />With EOS machines we build Inconel 718 parts or Co-Cr-Mo parts which can be used up to 1100ºC.<br />You are also right in terms of price calculation: the more parts on a building platform the lower the price per part.<br />EBM is cheaper and faster on bulky parts, no doubtcgpandohttps://www.blogger.com/profile/15631568307915566574noreply@blogger.comtag:blogger.com,1999:blog-1798970477996519510.post-7424500381444865032012-03-11T15:38:23.789-04:002012-03-11T15:38:23.789-04:00I'll admit I don't know much about EBM. H...I'll admit I don't know much about EBM. However, I understand that DMLS can achieve smaller minimum feature sizes and minimum wall thickness. Both are key features for building rocket combustion chambers. Also, DMLS often achieves properties that are as good or better than the wrought condition, so the material properties are quite good.RMhttps://www.blogger.com/profile/14180745747728028165noreply@blogger.comtag:blogger.com,1999:blog-1798970477996519510.post-22753768196976948662012-02-29T02:37:14.099-05:002012-02-29T02:37:14.099-05:00Hi,

I hear it's a superior technology, which can work with higher-temperature alloys, and achieves a better melt-quality.sanhttps://www.blogger.com/profile/11939342428337531046noreply@blogger.com
