Orientation and Supports
Part orientation affects support requirements and the surfaces that need cleanup, so it’s helpful to identify critical faces and mating features early in build preparation.
EOS M 400-4Metal 3D Printing Services
Complex metal parts shouldn't force you to compromise your design just to get them made. Evology Manufacturing's EOS M 400-4 expands our metal 3D printing capabilities for larger components and production batches. Using Direct Metal Laser Sintering (DMLS), it builds parts from metal powder, layer by layer, directly from your CAD model.
Bring us your design, material requirements, and production goals, and we'll help you determine where metal additive manufacturing fits.
How Metal 3D Printing Compares to Machining and Casting
Some parts are straightforward to machine, while others need internal passages, complex contours, or multiple components joined into one assembly. Metal 3D printing gives you another way to approach those designs, without first investing in casting molds.
The right choice depends on the complete part, including quantity, material, finishing, and inspection. We'll review those requirements with you so the manufacturing process supports the application.
EOS M 400-4 Capabilities
Our four-laser system adds room for larger designs and multiple parts within a single build.
400 × 400 × 400 mmNominal build volume, approximately 15.7 × 15.7 × 15.7 in.
Four 400-watt lasersParallel laser processing across the powder bed.
Dual Setup StationAutomated build-job exchange to reduce downtime between jobs.
The Build Volume
The published build envelope includes the build platform, but actual part fit also depends on orientation, supports, and build preparation. Send us your CAD file so we can check usable space for your design.
Material Selection
EOS lists aluminum, stainless steel, tool steel, nickel alloy, and titanium options for the M 400-4 platform. The right choice depends on the properties your application needs and the processes available for your job.
Ask us to confirm your alloy and its availability on this machine.
Less Waiting Between Builds with the Dual Setup Station
Our EOS M 400-4 is paired with the Grenzebach Dual Setup Station — EOS Edition, the dual setup and powder-handling workflow supporting this installation.
While a completed build cools and is unpacked, the next prepared job can start automatically. This separates printing from work that would otherwise keep the machine waiting between builds.
Delivery timing still depends on the build, material, finishing requirements, and schedule. We'll confirm those details when we quote your part.
Designing for the EOS M 400-4
A successful build starts with the finished part in mind. These considerations help us evaluate your design before production:
Internal Features and Powder Removal
Internal passages need a practical way to remove unfused powder, so include access for cleaning and flag enclosed cavities or difficult-to-reach channels for review.
Tolerances and Finishing
Specify required tolerances, surface finishes, and inspection criteria on your drawing. Machining or other finishing may be needed after printing, especially at sealing surfaces and precision interfaces. We’ll scope those operations as part of the job.
Part Complexity & Design Fit
Use these starting points to decide what to send for review. They describe potential process fit, not a guarantee of printability.
Strong Candidates
Complex components that are difficult to reach with cutting tools, assemblies that could be consolidated into fewer pieces, and functional prototypes that need to be tested in metal.
Needs a Closer Review
Thin walls, substantial overhangs, enclosed passages, and parts approaching the build envelope need a closer look, so include drawings and application details to help us evaluate the full manufacturing plan.
Compare Other Processes
Simple parts made in high quantities may have a stronger business case for machining or casting. We’ll help you compare options based on what the finished part needs to do.
Applications & Example Parts
Potential applications include manifolds with internal flow paths, compact heat exchangers, tooling inserts, lightweight brackets, and functional prototypes. Each requires an application-specific review of geometry, material, and finishing.

Frequently Asked Questions
What is the EOS M 400-4?
The EOS M 400-4 is an industrial metal 3D printer with four lasers, and it uses a laser powder bed fusion process, marketed by EOS as DMLS, to make metal components from digital designs.
What is the largest part you can print?
The nominal build volume is 400 × 400 × 400 mm, including the build platform. Usable part dimensions depend on orientation and supports, so we’ll review your model to confirm fit.
What does the dual powder system do?
The Grenzebach Dual Setup Station automates the exchange between prepared build jobs, allowing printing to continue while the previous job is handled outside the printer. Its purpose is to reduce non-productive time between builds.
Which metals are available?
Material availability is confirmed during quoting. Send us the required alloy, operating conditions, and any material specifications so we can recommend a suitable manufacturing route.
How accurate are metal 3D printed parts?
Achievable tolerances depend on the geometry, material, orientation, and finishing plan. Include your drawing with the CAD model so we can assess critical dimensions and identify any secondary operations.
Can I order prototypes and production parts?
We can review both one-off prototypes and recurring production requirements. Let us know your initial quantity, expected future demand, and testing or inspection needs so we can quote the right scope.
What do you need to quote my project?
Send your CAD model, drawing if available, quantity, required material, critical tolerances, and target delivery date. Include any finishing and documentation requirements. We’ll review the details and follow up with questions before finalizing the quote.
Have a Metal Part in Mind?
Let's find the right way to make it. Send us your design and we'll review it for the EOS M 400-4, confirm material and finishing requirements, and provide a quote with a project-specific timeline.
