TENGHUI provides SLM metal printing with material selection, post-processing, and inspection support. We review your CAD model and drawing to plan the steps needed for the finished component.
• Tolerances & Lead Time: Printing tolerances, minimum features, and production lead time are confirmed for your design upon engineering review.
• Drawing Requirements: Please include a 2D drawing for critical dimensions, datums, surface roughness, and documentation requirements.
Selective laser melting (SLM) is a laser powder bed fusion process that builds metal parts directly from CAD data. A high-precision laser selectively melts metal powder layer by layer to create dense, fully metallic components.
SLM is particularly useful for complex internal channels, lightweight lattice structures, and consolidated designs that combine multiple components into a single part. After printing, parts undergo support removal, stress-relief heat treatment, CNC post-machining, and custom surface finishing tailored to their intended end use.
Choose a material based on weight, strength, corrosion resistance, and operating temperature. Specific alloy grades and heat treatment specifications are confirmed during quotation.
Suitable for lightweight prototypes, housings, brackets, and thermal-management components. The selected alloy matches your mechanical, temperature, and finishing requirements.
Suitable for corrosion-resistant prototypes, housings, and complex industrial components. Specify the service environment and required material condition when requesting a quotation.
Suitable for selected tooling, mold inserts, and components with internal cooling channels. Required hardness, wear resistance, and heat treatment should be defined before production.
Suitable for components where low weight, high strength, and corrosion resistance are critical. Provide your required alloy grade, mechanical properties, and inspection criteria.
Need guidance on alloy selection or heat treatment? Share your application conditions and load requirements for tailored engineering support.
Consult an EngineerSeamlessly bridge the gap between additive manufacturing freedom and subtractive precision machining. Here is how our comprehensive SLM engineering workflow supports your critical parts:
Produce internal channels, hollow sections, and intricate shapes that are difficult to manufacture using conventional methods. Suitable designs can also combine multiple components to reduce assembly steps.
Combine the design flexibility of metal printing with in-house CNC machining for critical interfaces. Planning both processes together helps address machining access, locating features, and final dimensional requirements.
We review material requirements, thin walls, support access, and powder removal paths to identify manufacturing issues before printing, ensuring optimal laser build parameters.
Parts are checked against agreed dimensional and appearance requirements. Inspection reports and material documentation can be specified during quotation, with availability confirmed before production.

Get a QuotePost-processing prepares printed parts for their intended use. Specify the required material condition, dimensions, surface roughness, and appearance when requesting a quotation.
Remove accessible supports and clean up contact areas before further processing. Removal access and witness mark criteria are fully evaluated during initial build planning.
Create a more uniform matte appearance on accessible surfaces. Helps blend micro-steps and remove light oxidation, though some native printed texture may remain.
Improve accessible external surfaces for tactile handling or aesthetic display. Finished quality depends directly on the selected metal alloy, geometry, and starting surface condition.
Finish critical mating surfaces, bearing seats, precision holes, and threads to agreed 2D drawing requirements. Machining stock allowances and fixturing datums are planned prior to printing.
Apply furnace stress relief, annealing, or solution aging to eliminate internal residual thermal stress and optimize tensile or hardness properties tailored to your alloy and application.
Anodizing (for aluminum), chemical passivation, electroplating, and other compatible treatments can be reviewed for enhanced corrosion protection, wear resistance, or appearance.
Engineering Note: The processing sequence and achievable surface finish are confirmed during quotation based on part orientation and critical tolerances.
Optimize your CAD models for direct metal laser melting. Incorporating these design considerations ensures build stability, prevents thermal distortion, and streamlines post-machining.
Overhangs may require supports depending on geometry and build orientation. Avoid designs that leave supports trapped inside inaccessible features.
Hollow sections and internal channels need suitable openings for removing loose powder. Channel size, length, bends, and cleaning access should be reviewed together.
Mark tolerances, datums, threads, and surface roughness on a 2D drawing. Identify which dimensions apply after machining or coating so the manufacturing and inspection plan can be defined correctly.
Thin walls, large flat sections, and abrupt changes in thickness may be prone to distortion. Wall thickness, build orientation, supports, and heat treatment should be considered before production.
Need a Design Review? Our engineering team checks your CAD models for support placement, thermal stress, and post-machining datums before quoting.
Metal printing is worth considering for internal channels, lightweight structures, and complex geometry that is difficult to machine. CNC machining may be more economical for simpler shapes or parts dominated by precision features.
TENGHUI can review your design and recommend printing, machining, or a combination of both.
Maximum part size varies by alloy, equipment, geometry, and build orientation. Send your CAD files so we can confirm feasibility for the required material.
As-printed accuracy depends on material, part size, geometry, and orientation. Critical features may require CNC post-machining.
Provide a dimensioned drawing so we can confirm achievable tolerances before production.
As-printed surfaces have a textured appearance and may show support contact marks. Blasting, polishing, or machining can improve selected areas.
Specify visible surfaces, roughness values, and sealing requirements during quotation.
Mechanical performance depends on the alloy, printing conditions, orientation, heat treatment, and surface condition.
For specified strength or fatigue requirements, material condition, testing, and acceptance criteria must be agreed before production.
Specify the documents, material traceability, and inspection scope you need when requesting a quotation. Availability and any additional cost will be confirmed before production.
Production lead time depends on material availability, part size, quantity, post-processing, and inspection requirements. Your quotation confirms the schedule. Shipping time is additional.
If you have any questions or would like to book a session please contact us.
Once we receive your design files, our senior manufacturing engineers will manually perform a comprehensive DFM review and deliver an accurate, optimized quote within 24 hours.
