Eternal M1 Industrial Resin 3D Printer
A 13.6-inch 7K LCD resin 3D printing system for engineering prototypes, product development, large resin parts, jigs and fixtures, multi-part builds and suitable low-volume production workflows.
298 × 165 × 370 mmBuild volume
13.6-inch · 7KMonochrome LCD exposure screen
46 μmXY pixel size / display accuracy
405 nm UVLight wavelength
XY pixel size and display resolution describe the exposure system. They do not define a universal finished-part dimensional accuracy.
Application Fit
Use the M1 when the part and workflow fit the system.
Build volume matters, but it is only one selection factor. The practical decision also depends on geometry, critical interfaces, resin requirements, build orientation, quantity, post-processing and the inspection method used on the finished part.

Build Around the Part
Start with what the finished part must prove.
A useful equipment decision begins with the model and acceptance question, not a resolution label. Share the actual part where possible, then define the printer, resin and workflow around it.
- Part envelopeOverall dimensions plus the oriented geometry, supports and practical removal space.
- Critical geometryHoles, slots, thin walls, ribs, interfaces, flat spans, recesses and support-sensitive faces.
- Material requirementRigidity, toughness, appearance, flexibility or other application-specific behavior that must be validated.
- Quantity & layoutOne prototype, multiple related parts or a repeatable batch with planned spacing and support strategy.
- Surface & assemblyAppearance surfaces, mating faces, clearances and areas that need direct inspection after finishing.
- Final useAppearance review, fit check, engineering validation, temporary production aid or another clearly defined task.
Key System Features
Published equipment characteristics, separated from finished-part claims.
The specifications below describe the M1 printing system. Actual printed results still depend on the resin, geometry, orientation, layer thickness, supports, exposure settings, environment, washing, drying, UV post-curing and inspection conditions.
298 × 165 × 370 mm build volume
Use the full oriented model, support footprint and downstream handling requirements when deciding whether the build envelope is appropriate.
46 μm XY pixel size
XY pixel size describes the nominal pixel pitch at the exposure plane. Finished dimensions require project-specific validation after the complete process.
405 nm UV parallel-light architecture
The wavelength and light-source architecture guide resin compatibility and process setup; they do not by themselves establish surface finish or dimensional performance.
0.02–0.10 mm published layer thickness range
Layer thickness affects the build strategy and process time. Appropriate settings depend on the resin, geometry and validation requirement.
Enclosed industrial cabinet with front control interface
The supplied M1 reference sheet shows an enclosed cabinet architecture intended for a professional resin-printing workspace. Installation planning should use the latest formal product documentation.
Industrial Applications
Evaluate the M1 against the actual engineering task.
The same printer can support different workflows, but each one needs its own material, build preparation, post-processing and inspection plan.

Engineering Prototypes
Dimensional geometry, interfaces, housings, brackets and other physical engineering models.
Product Development
Appearance, fit, assembly and selected geometry-led functional checks during iteration.
Large Models & Housings
Prototype shells and larger resin parts where orientation, supports, drainage and post-processing remain practical.
Assembly & Fit Validation
Mating features, holes, slots, interfaces and clearances reviewed against CAD or real components.
Jigs & Fixtures
Positioning tools, checking fixtures and production aids evaluated for their actual load and service conditions.
Multi-Part Builds
Planned arrangements of related parts with attention to spacing, support strategy and downstream handling.
Suitable Low-Volume Production
Controlled batches when geometry, resin, workflow capacity, inspection criteria and economics align.
Representative Sample Validation
Test the geometry that matters before locking in the process.
A generic demo part can show that a machine prints. A representative project model is more useful for checking the dimensions, interfaces, surfaces, resin handling and post-processing conditions that affect the real decision.
- Submit the model and requirementShare overall size, critical features, material direction, quantity, surface expectations and intended use.
- Match printer and resinChoose a practical equipment and material direction for the actual part rather than a generic profile.
- Prepare the buildPlan orientation, supports, drainage, critical faces and multi-part layout around the validation task.
- Complete the full processPrint, wash, completely dry, UV post-cure and finish as required before evaluation.
- Inspect the finished partMeasure and assemble against project-specific criteria instead of converting a screen specification into a tolerance.
Complete Resin Workflow
The part is not finished when the build stops.
For engineering decisions, evaluate the part after the complete resin workflow. Washing, complete drying and UV post-curing can influence the state in which the part is finally measured, assembled and reviewed.

Materials & Post-Processing
Confirm the material and the finished-part workflow together.
Do not assume universal resin compatibility. Confirm current resin compatibility for the intended application, then validate printing, washing, complete drying, UV post-curing and inspection as one connected workflow.
Resin Materials
Choose material direction according to the part's required behavior, appearance, geometry, printer compatibility and post-processing needs. Use technical documentation and representative testing before committing to a production workflow.

FAQ
Questions to answer before choosing Eternal M1
Is M1 suitable for my part size?
Start with the fully oriented model and planned support footprint, not only the CAD bounding box. M1 has a published 298 × 165 × 370 mm build volume, but practical fit also depends on orientation, supports, drainage, removal, washing, post-curing and inspection access.
What affects finished-part dimensional accuracy?
Finished dimensions can be influenced by resin, geometry, orientation, layer thickness, support strategy, exposure settings, environmental conditions, washing, complete drying, UV post-curing, finishing and the measurement method. The 46 μm XY pixel size is an exposure-system specification, not a guaranteed finished-part tolerance.
Which resin should I use with the M1?
Select resin according to the part behavior, geometry, surface requirements, post-processing method and intended use. Confirm current M1 compatibility for the specific resin and application, then validate a representative part before committing to the workflow.
Can I submit my own model for testing?
Yes. Use the current Request a Quote / Submit Your Model page and share the representative model together with overall dimensions, critical features, material requirements, quantity, surface expectations and intended application.
Can M1 be evaluated for low-volume production?
Yes, where the geometry, resin, multi-part layout, post-processing capacity, inspection criteria and economics are appropriate. A representative batch is more useful than a single ideal sample when the real question is repeatable output.
What information is needed for a quotation?
Provide the model or key dimensions, intended application, material or part-behavior requirement, quantity, critical features, surface or fit requirements, destination and any relevant post-processing or documentation needs.
