Friendly Reminder from DT
I. The Metal 3D Printing Materials commonly used for SLM in DT
- アルミニウム合金 (AlSi10Mg)
- ステンレス鋼 (347, 316L, 304L, 17-4 and more)
- Die Steel (CX, 1.2709)
- チタン合金 (TC4)
II. Printing Precautions from DT
- DT Industrial 3D Printers: The power is 500W (dual-laser).
- Printing Layer Thickness: 0.03mm, 0.06mm, 0.09mm.
- Natural Surface Features: Pitting (surface roughness: approx. Ra 16).
- Placement Direction: Generally, flat placement or 45° inclined placement delivers the best print quality.
- Printing Tolerance: For products with a size of 50mm or less, the printing tolerance is approximately ±0.2mm. For larger products, the printing tolerance will be determined based on the drawings.
- Note: Wall thickness, groove width, groove depth, structural clearance, and font size that are less than 0.5mm cannot be guaranteed to be printable.
- Note: The hole diameter should not be less than 0.8mm. Generally, the hole diameter will shrink by approximately 0.2mm after printing.
- Note: For threads (including internal and external threads), tapping is recommended rather than direct printing.
- Post-processing of Metal 3D Printing Materials: Similar to traditional materials, these materials can undergo further processing.
- For Assembled Parts: Please be reminded to provide the assembly drawings. The parts will be assembled before delivery. If no such reminder is provided, we will not be responsible for assembly.
- Note: For products with assembly clearance positions, a unilateral allowance of 0.15mm must be reserved.
- Note: For parts with high-precision local assembly requirements (such as bearing holes, diameters, or flat assembly positions), machining allowances must be reserved in advance, and the parts should then be matched through secondary finishing.
- Note: After high-temperature sintering in metal 3D printing, some slender parts, thin-walled parts, and shell-like structures may deform. The advantage of metal 3D printing lies in manufacturing parts with complex structures, while its accuracy and surface finish are inferior to those of CNC machining.
- Note: For products requiring secondary processing, we must confirm with the customer whether the 3D drawing has included allowances. If allowances have not been included, we must communicate with the engineering department or make a note on the production order: Appropriate allowances for secondary processing must be reserved before printing.
