Technical Service Overview Reviewed by APJ 3D Engineering Desk • Updated September 2026

What is SLA 3D Printing Services Chennai?

Industrial 3D Printing (Additive Manufacturing) is the tool-less, layer-by-layer fabrication of physical parts directly from 3D CAD data using industrial technologies including HP Multi Jet Fusion (MJF), Selective Laser Sintering (SLS), Stereolithography (SLA), Fused Deposition Modeling (FDM), and Direct Metal Laser Sintering (DMLS).

When to Select This Service

Choose industrial 3D printing when rapid prototypes are required in 24–48 hours, for low-volume bridge production (50 to 5,000 units) without tooling CapEx, or for complex internal channels and lattice lightweighting impossible to machine conventionally.

FAQ

Frequently Asked Questions

Which 3D printing process is right for my application?

For functional, airtight plastic assemblies and batch runs (50–5,000 parts), HP MJF with PA12 or PA11 is optimal. For high-detail visual prototypes and master patterns, SLA is best. For end-use aerospace or medical metal brackets, Metal DMLS (AlSi10Mg / 316L) is recommended.

How does 3D printing cost compare to injection moulding?

3D printing has $0 tooling cost and low setup time, making it significantly cheaper for quantities between 1 and 5,000 parts. Injection moulding requires expensive upfront tooling ($3,000–$25,000) and 4–8 weeks lead time, only becoming economical above 10,000 units.

What CAD file formats are accepted for 3D printing quotes?

We accept standard 3D solid formats including STEP (.step, .stp), Parasolid (.x_t), IGES (.igs), and STL (.stl). Native CAD files from SolidWorks, NX, and CATIA are also supported.

What is the typical turnaround time for orders in India?

Standard functional prototypes are dispatched within 24 to 48 hours. Batch production runs of 100 to 5,000 parts deliver within 3 to 5 business days with pan-India express courier delivery.

Can 3D printed parts be tapped with threads or post-machined?

Yes. We offer secondary CNC machining, brass threaded heat-stake inserts, reaming, tapping, vapor smoothing, and painting to meet end-use assembly specifications.
