BCN3D Stratos vs Eiger

BCN3D Stratos is free slicing software for preparing 3D prints with BCN3D Omega, Sigma, and Epsilon printers. It imports STL, 3MF, OBJ, and AMF files, then lets users translate, scale, and rotate parts. Validated printing profiles are included, while expert users can adjust more than 500 parameters. For IDEX technology, the slicer supports multi-material models, support structures, mirror mode, and duplication mode for two print heads. Layer View displays print sections; X-ray View reveals internal parts and hidden geometries. Completed G-code can be sent to a networked printer or saved to removable media such as an SD card. Other listed options include gyroid infill, brim and raft adhesion settings, and bridges. BCN3D says Stratos is based on the open-source slicer Cura. It runs on 64-bit Windows 10 or higher, Mac OSX 10.11 or higher, and Linux, but is not available for older 32-bit systems. The product page links to a knowledge base, onboarding video, and feature tutorials. The listed plan is free.

Eiger is Markforged software for preparing 3D prints and managing printer activity. In its browser-based workflow, users import STL or STEP files, arrange parts into a build, set slicing and fiber routing, and generate an MFP file for a Markforged printer. Selective fiber reinforcement controls support routing reinforcement within a part. Eiger also provides printer and print-activity management in one place. The free cloud platform is for Markforged devices; the maker describes it as suitable for institutions with one to one hundred printers. Cloud use requires an internet connection to upload, create, view, and share part, build, and print-job data. Offline Eiger runs without internet access and does not send user or part data to the cloud. Offline print files must be transferred by USB, or over a local network with LAN Connector installed. The Essential plan includes Job Requests for submitting, tracking, and fulfilling print requests. Blacksmith is an Eiger subscription feature for scanning printed parts and comparing them with design files. The maker says cloud build files are encrypted in transit and at rest, and that Eiger earned ISO 27001 certification.
