Tenghui and our manufacturing network support a wide range of advanced technologies. Here is how we help you move faster, reduce engineering costs, and achieve consistent, production-grade results:
Upload your 3D CAD files to receive a professional quotation within 24 hours. From single functional prototypes to active production runs of complex parts, our flexible manufacturing setup ensures high consistency and competitive pricing, helping you accelerate your product development cycle without unnecessary delays.
Tenghui offers a seamless transition from one-off engineering prototypes to scalable low-volume production. Whether you need 10 or 1,000 units, our industrial 3D printing solutions provide production-level quality without the high initial costs and long lead times of traditional tooling, keeping your project agile.
Small teams often lack in-house manufacturing experts. Our engineering specialists provide complimentary Design for Manufacturability (DFM) feedback on every project, covering part orientation, material selection, and tolerance analysis to ensure your 3D printed parts are optimized for performance and cost.
We are proud to maintain a rigorous quality management system that governs every individual stage of our 3D printing workflow. From incoming material verification to final multi-dimensional verification, our control process includes advanced coordinate measuring machine (CMM) analysis and detailed first-article inspection reports.
Enhance the durability, corrosion resistance, and cosmetic appearance of your 3D printed parts with our comprehensive post-processing treatments.
Removes layer lines, build steps, and tool marks to produce a uniform, tactilely smooth surface. Suitable for appearance models, clear resins, and high-end mirror finishes.
Applied to metal 3D printed components (such as SLM aluminum). Electrochemical oxidation forms a hard, corrosion-resistant oxide layer available in clear, black, or custom vibrant colors.
Deposits a real metallic shell (chrome, nickel, copper, or gold) onto resin or polymer surfaces. Delivers superior wear resistance, EMI shielding, and authentic metallic luster.
Applies automotive-grade polyurethane paints or protective clear coats. Matches precise Pantone and RAL references with custom matte, satin, or high-gloss sheen options.
Engineering Note: Surface finishing may add or remove micro-thickness (0.02 – 0.1 mm). Please indicate critical mating features, hole diameters, and masked areas on your drawings.
TENGHUI offers SLA, SLS, HP Multi Jet Fusion (MJF), metal 3D printing, and ceramic 3D printing through our manufacturing capabilities and qualified production partners. Our engineers recommend a suitable process based on your material, geometry, functional requirements, quantity, and budget.
SLA is suitable for detailed appearance models and prototypes requiring smooth surfaces. SLS and MJF are commonly used for functional nylon parts and low-volume production. Metal 3D printing supports complex metal components, while ceramic printing serves applications requiring specific thermal, wear, or electrical properties.
The final recommendation depends on your design and intended operating conditions.
Available options include photopolymer resins, PA11 and PA12 nylon, selected reinforced polymers, TPU, stainless steel, aluminum alloys, titanium alloys, and technical ceramics.
Material availability depends on the printing process. Please specify your requirements for strength, flexibility, temperature resistance, chemical exposure, or appearance so we can recommend an appropriate grade.
Achievable tolerances depend on the process, material, part size, build orientation, geometry, and post-processing. Layer thickness describes the printing increment and should not be treated as the finished part’s dimensional tolerance.
Please identify critical dimensions and inspection requirements on your 2D drawing. We will confirm achievable tolerances during quotation and may recommend secondary machining for precision interfaces.
Build size and minimum wall thickness vary by process, material, and equipment. Thin walls, unsupported features, large flat surfaces, and enclosed cavities require additional review.
Send your CAD model for a project-specific assessment. We will confirm build feasibility, wall thickness, support requirements, and whether splitting the part is advisable.
Yes. Depending on the material and application, we can evaluate printed threads, tapped holes, captive nuts, or threaded inserts.
Heat-set inserts may be suitable for compatible thermoplastics such as selected SLS or MJF nylons. SLA resins are thermosets and generally require alternative methods, such as bonded or suitable press-in inserts. Functional connections should be reviewed for assembly torque and retention requirements.
Depending on the material and process, options may include support removal, cleaning, curing, sanding, bead blasting, painting, dyeing, polishing, CNC machining, and heat treatment.
Metal-specific treatments, such as anodizing or hot isostatic pressing (HIP), are evaluated according to the alloy and application. Finishing can affect dimensions, so critical surfaces and final tolerances should be specified before quotation.
Lead time depends on the selected process, material availability, part size, quantity, post-processing, and inspection requirements.
We confirm a project-specific production schedule with your quotation. Please provide your required delivery date and destination so production time and shipping time can be evaluated separately.
Yes, when the selected material, manufacturing process, and part design meet the application’s requirements. Performance may vary with build orientation, environmental exposure, post-processing, and loading conditions.
Medical, food-contact, pressure-containing, or other demanding applications require specific material documentation, testing, and validation. These requirements should be defined before production.
Please provide a STEP/STP or STL model, together with a dimensioned PDF drawing where tolerances or inspection requirements apply.
Include the material or required properties, quantity, units, surface finish, intended use, critical dimensions, and target delivery date. For STL files, specify the model units and provide a sufficiently detailed, watertight mesh.
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.
