Choose the Right Printing Process

Match the process to geometry, material, accuracy, appearance, load, quantity, and the intended use of the part.

FDM / FFF

Thermoplastic filament printing for economical concept models, fixtures, and functional prototypes.

Review layer direction, infill, supports, bed adhesion, and visible layer lines.

SLA / DLP

Photopolymer printing for fine detail, smooth surfaces, and presentation or functional trials.

Supports, washing, and resin-specific curing influence final size and material behavior.

SLS

Polymer powder-bed printing for complex nylon parts and low-volume functional assemblies.

Surrounding powder supports the build; powder removal, access, and thermal distortion still need review.

금속 분말 베드 용융법

Metal printing for reviewed complex structures, lightweight geometry, and consolidated components.

Confirm alloy availability, orientation, supports, heat treatment, distortion, and feature finishing.

3D Printing Capability References

These planning figures are reviewed for the selected process and machine. Part dimensions, orientation, supports, material, and finishing determine the accepted requirement.

Drawing-Based Parameters

Build-size referenceUp to 750 × 550 × 550 mm*Platform-specific; this envelope is not available for every process or material. Supports and build clearance also affect usable size.
Typical dimensional reference±0.10–0.30 mm*Subject to process, feature size, material, orientation, geometry, and inspection condition.
주요 정밀도 사양Down to ±0.05 mm*Accepted only after feature-specific review; the finishing and measurement route is agreed before production.
Minimum-wall referencesSLA: 0.3 mm / FDM: 0.8 mm*Local design references, dependent on material, supported height, span, orientation, and function.
Hole-size referenceAbout 1.5 mm before finishing*Review axis, depth, shape, cleaning access, and any required drilling or reaming.
Layer-height reference0.05–0.30 mm*Selected platform settings. Layer height is not the same as dimensional accuracy or guaranteed surface roughness.

통제된 생산 공정

1. Model and Job Review

Confirm revision, units, geometry, process, material, orientation, critical features, and acceptance criteria.

2. Build Control

Manage material condition, approved machine settings, support strategy, and the planned build.

3. Finishing and Inspection

3D Printing Project Questions

Which file formats should I send?

STEP is preferred for engineering review. STL, 3MF, and OBJ files can be reviewed with clear units, scale, and suitable mesh quality. Add a dimensioned PDF for tolerances, datums, and features that need inspection.

Does a smaller layer height guarantee tighter tolerances?

No. Layer height affects build resolution and surface stepping, but dimensional results also depend on the machine, material, geometry, orientation, calibration, thermal behavior, and post-processing.

보이는 레이어 선을 어떻게 줄일 수 있을까요?

Choose a suitable process and orientation, then review layer settings and compatible finishing. Sanding, polishing, blasting, or coating may alter dimensions. Resin curing establishes properties but does not by itself remove visible stepping.

What causes warping?

Uneven thermal conditions, shrinkage, moisture, support or bed-adhesion problems, and unbalanced geometry can contribute. Controls are selected for the process rather than applying one method to all printing technologies.

3D 프린팅으로 제작된 부품의 강도는 어느 정도인가요?

Strength depends on grade, process, orientation, infill where applicable, layer bonding, defects, and post-processing. Review the actual loading and test condition instead of treating bulk-material data as guaranteed printed performance.

When should another manufacturing process be considered?

Machining or molding may be more suitable when stock-material properties, tight fits, surface requirements, or repeat-volume economics are the priority. Compare the full production and finishing route.
