Rapid Prototyping:
We offers a variety of Rapid Prototyping techniques which may differ greatly in terms of the range of materials, build envelop, dimensional accuracy surface finish and other factors. Rapid prototyping technology makes it possible to hold a physical model in hand the day after concept design
The Rapid Prototyping techniques we offer include
1) Stereo-Lithography (SLA):
Principle and process:
- This is based on selective polymerization of a photosensitive resin using ultraviolet light.
- In this system, an ultraviolet laser beam is focused on the top layer of photo sensitive resin contained in a vat.
- The beam is positions and moved in horizontal X and Y directions to polymerize the resin within the boundary a particular cross-section.
- The cured layer of polymer is lowered by a platform attached to it, so that a fresh layer of liquid resin covers the cured layer.
Advantages:
- Achieving accuracy in industries.
- Market shares and industry presence.
- Capable of high detail and thin walls.
- Good surface finish.
Limitations:
- Requires post-curing.
- Some war page, shrinkage and curl due to phase change.
- Limited materials (Photo polymers).
- Support structures always needed. Removal of support structures can be difficult.
2) Selective Laser Sintering (SLS):
Principle and process:
- In this process a high power laser beam selectively melts and fuses powdered material spread on a layer.
- The powder is metered in precise amounts and is spread by a counter-rotating roller on the table.
- A laser beam is used to fuse the powder within the section boundary through a cross-hatching motion.
- The table is lowered through a distance corresponding to the layer thickness (usually 0.01 mm) before the roller spreads the next layer of powder on the previously built layer.
- The uninsured powder serves as the support for overhanging portions, if any in the subsequent layers.
Advantages:
- The main advantage is that the fabricated prototypes are porous (typically 60 percent of the density of molded parts), thus impairing their strength and surface finish.
- Variety of materials.
- No post curing required.
- Fast build times.
- Limited use of support structures.
- Mechanical properties of Nylon & Polycarbonate parts.
Limitations
- Rough surface finish.
- Mechanical properties below those achieved in injection molding process for same material.
- Many build variables, complex operation.
- Material changeover difficult compared to FDM and SLA.
- Some post-processing / finishing required.
3) Fused Deposition Modeling (FDM)
Principle and process:
- The FDM technique relies on melting and selectively depositing a thin filament of thermoplastic polymer (ABS - engineering and medical grade - plastic, Polycarbonate and investment casting wax) in a cross-hatching fashion to form each layer of the part.
- The material is in the form of a wire supplied in sealed spools which is mounted on the machine and the wire is threaded through the FDM head.
- The head is moved in the horizontal X and Y directions for producing each layer through zigzag movements.
- The supporting table moves in the vertical direction and is lowered after the completion of each layer.
Advantages:
- No post curing
- Variety of materials
- Easy material changeover
- Office environment friendly
- Low end, economical machines
Limitations:
- Not good for small features, details and thin walls
- Surface finish
- Supports required on some materials / geometries
- Support design / integration / removal is difficult
- Weak Z-axis
- Slow on large / dense parts
