Amsol's Position
3D Printing Is Not a Replacement.
3D Printing Is Not a Replacement.
It Is the Bridge.
Casting, forging, and machining remain the right processes for production. But between drawing approval and first production casting — there is a gap that costs weeks. 3D printing closes that gap. Amsol positions additive manufacturing as the bridge between design and tooling commitment — not as a substitute for either.

The most expensive mistake in manufacturing is committing to production tooling before the design is proven. A casting tool costs ₹3–15 lakhs and takes 6–10 weeks. A 3D printed prototype costs a fraction and arrives in 48 hours.
Amsol uses 3D printing to validate designs before tooling, supply bridge quantities while tooling is made, test fit and function before serial production begins, and provide customer approval samples with no lead time. Then — once the design is proven — we move to the right production process.
Five Processes Explained
Which Process. Which Application. Which Material.
Five additive manufacturing processes at Amsol — each right for a different application. Understanding which to use prevents over-specifying and over-spending on prototypes.
🖨️ FDM — Fused Deposition
Concept Model in 24 Hours. Zero Cost to Change.
FDM deposits molten thermoplastic filament layer by layer — the fastest and lowest-cost additive process. Best for concept models, fit-check prototypes, jigs and fixtures, and any application where visual or spatial verification matters more than surface finish or mechanical properties. PLA, ABS, PETG, and engineering-grade ASA or Nylon available.

💡 SLA + ⬜ SLS / MJF
SLA: Ra 0.8 Surface. SLS/MJF: No Supports, Complex Geometry.
SLA (Stereolithography) cures photopolymer resin with a UV laser — producing Ra 0.8 µm surface finish and ±0.1mm accuracy that far exceeds FDM. Used for optical components, dental models, jewellery casting patterns, and any application requiring visible surface quality. SLS and MJF sinter nylon powder — no support material, meaning any geometry is achievable including internal lattices, inter-locking parts, and complex internal channels.

Metal 3D Printing
DMLS — The Most Technically Capable Additive Process.
DMLS (Direct Metal Laser Sintering) produces fully dense metal parts with mechanical properties comparable to wrought material — in any geometry, regardless of undercuts, internal passages, or re-entrant features impossible in casting or machining.
DMLS / SLM — Direct Metal Laser Sintering
A high-powered laser selectively fuses metal powder layer by layer. The build chamber is inert-gas purged to prevent oxidation. The result: fully dense metal parts with 99.9% density, tensile properties matching or exceeding cast equivalents, and geometric freedom that conventional manufacturing cannot achieve.

Where DMLS adds value over casting
✓Complex internal cooling channels impossible in casting
✓No draft angles — walls can be truly vertical or re-entrant
✓Topology-optimised structures — minimum weight maximum strength
✓Bridge production: parts while casting tooling is being made
Decision Guide
Which Process for Which Application
The right additive process depends on what you need it for. Use this guide — or share your drawing and Amsol will recommend.
Use FDM or SLA When
Visual verification and customer approval samples — speed and low cost matter most, mechanical properties secondary.
Concept model for customer or internal review
Fit check before production tooling commitment
Assembly jigs and inspection fixtures
Lost wax casting patterns (SLA)
Typical turnaround: 24–48 hours · Lowest cost
Use SLS / MJF When
Functional nylon parts with complex geometry — internal channels, interlocking features, assemblies that cannot be made in any other process without tooling.
Complex internal geometry — no support marks
Functional snap-fit assemblies
Low-volume production of nylon components
Bridge production while injection tooling is made
Typical turnaround: 3–5 days · Medium cost
Use DMLS When
Functional metal parts with full mechanical properties — where casting lead time is too long, tooling cost is not justified, or geometry is impossible by conventional means.
Functional prototype while casting tooling is made
Complex internal cooling channels or passages
Topology-optimised aerospace/defence components
Bridge production: 1–50 metal parts quickly
Typical turnaround: 48–72 hours · Higher cost
