Sand blasting (improved appearance and feel)
Used to reduce metal printing surface roughness and powder sintering marks to obtain a more uniform matte appearance; more friendly to non-sealed appearance surfaces.
Nickel-Based Superalloy
Nickel-Based Superalloy is a metal 3D-printing option for high-temperature parts that require strength, reliability, and complex internal geometry.
Quote checklist: Upload your 3D model and, when available, a 2D drawing. Identify the required process, material, quantity, critical dimensions, finish, appearance standard, and target delivery date.
Key Material and Manufacturing Parameters
Engineering note: Values below are typical reference ranges. Final manufacturability, tolerances, material condition, surface finish, cost, and lead time depend on the drawing, geometry, quantity, and selected process.
Upload CAD files and mark critical features for an engineering review before production.
| Process | SLM metal 3D printing (nickel-based superalloys) |
|---|---|
| Material system | Nickel-based high-temperature alloy (high temperature resistance is preferred; suitable for one-piece molding of complex structures) |
| Dimensional tolerance | ±0.20 mm (common reference; it is recommended to mark tolerances and reserve finishing allowance for key mating surfaces) |
| Minimum wall thickness | ≥ 1.0 mm (Thin-walled/long cantilevers are recommended to be reinforced and optimally placed to avoid the risk of deformation and cracking) |
| Minimum aperture | Recommended ≥ 2.0–3.0 mm (deep holes/internal cavities need to be evaluated for cleaning; it is recommended to leave a margin for assembly holes before tapping/reaming) |
| Layer thickness | Commonly used 0.03–0.06 mm (equipment/parameter dependent; thinner layer thickness usually improves detail but increases cost) |
| Service temperature | 650℃ (please note the maximum temperature, duration and medium for high temperature working conditions) |
| Tensile strength | 900–1300 MPa (related to heat treatment status/build direction) |
| Density | 8.2 g/cm³ |
| Surface roughness | The formed surface is relatively rough; sandblasting can improve the appearance and feel, and finishing is recommended for sealing/mating surfaces. |
| Heat treatment/performance criteria | Heat treatment and stress relief can be evaluated according to working conditions; if you need to benchmark the criteria of a standard grade, please specify it in the remarks. |
| Assembly and threading | support Tapping; Please indicate the thread specification (such as M3/M4/M5, etc.), quantity and location. It is recommended to provide 2D annotations and fit requirements for critical assembly holes. |
| Finishing | Sand blasting and tapping |
| Typical lead time | Related to size, quantity, placement, whether heat treatment and finishing are required; clear delivery and expedited options will be given after uploading the file |
Finishing
Tapping (assembly interface)
Suitable for screw connections and assembly verification. Please provide thread specifications, number of holes and key hole matching requirements in the remarks; under high temperature conditions, it is recommended to clarify the assembly method and force direction.
Why Choose Nickel-Based Superalloys (SLM)
More stable under high temperature conditions
Facing the hot-end environment and high-temperature functional validation requirements, it is easier to maintain structural performance and reliability at higher temperatures.
Complex structure integration
Suitable for complex internal flow channels, topology optimization and integrated structures, reducing welding/assembly and shortening iteration cycles.
Controllable strength and size
Through placement optimization, heat treatment and key surface finishing, more controllable assembly accuracy and strength can be achieved.
Finishing straight to assembly
support Sand blasting + tapping Quickly enter assembly verification; secondary processing strategies can be combined with key hole locations to improve consistency.
Recommended Applications
- High temperature resistance functional validation: Structure/assembly/thermal impact verification in high temperature environment
- Complex internal cavities/internal channels: Structures that are difficult to achieve or extremely costly to process with traditional methods
- Integrated replacement of multi-piece assembly: Reduce welding and assembly errors and shorten lead time
- Requires thread assembly: The assembly interface can be obtained through tapping
It is not recommended to use it directly (it is recommended to change materials/processes)
- Simple structure and cost sensitive: It can be evaluated that CNC machining is more economical
- Sealing/mating surface requirements are extremely high: It is recommended to reserve finishing allowance and clarify tolerances
- Ultra-thin long cantilever without reinforcement: The risk of deformation/cracking is high, and structural optimization needs to be done first
- The inner cavity cannot be cleaned: Closed flow channels or ultra-thin channels need to be reviewed for manufacturability first.
Design and DFM Guidelines
- Reserve finishing allowance on key surfaces: It is recommended to reserve machining allowance for the sealing surface/fitting surface/positioning datum, and clarify the tolerance and datum system in the 2D mark.
- Thin wall and thermal deformation control: For thin-walled (close to the minimum wall thickness) and long cantilever structures, it is recommended to reinforce and make rounded transitions, and to reduce thermal stress concentration through placement.
- Powder cleaning and discharge of inner cavity/internal flow channel: Leave an outlet and path for the cleaning powder to avoid "closed cavity + thin channel"; if necessary, add a cleaning window or split the structure.
- Hole location and thread strategy: It is recommended to "reserve for printing + secondary processing/tapping" for assembly holes; please clarify the thread specifications and number of holes. It is recommended to provide 2D markings for key holes.
- Support and surface requirements: The appearance surface/key surface should avoid support contact as much as possible; sandblasting can be used to unify the texture for appearance consistency, and finishing is still recommended for key surfaces.
