When the number of quantities are less, opting for tooling is not a viable option. We understand the continuous need of on-demand manufacturing and hence Chizel offers three different manufacturing processes, which can be used to manufacture small batches in short lead times.
Please note, it is unreasonable to expect all the Batch production material properties to simulate with those of injection moulded parts as the technology and material properties differ. We help you prioritize your need and we recommend you the best material that may perform close to your final production parts.
Chizel is India’s leader in 3D printing batch production runs. We use Selective Laser Sintering (SLS) process to manufacture low volume products. Our design engineers optimise your design and stack it through out the build volume to achieve consistent precision. For low volume runs, we recommend smaller and intricate parts over bigger and simpler geometries to achieve cost benefits over conventional manufacturing.
Ideal batch size depends on the overall size of the component. We can print anywhere from 10-1000 parts depending on the geometry.
All the parts can be manufactured in less than 15 days including finishing processes. If you choose to go without finishing, we can deliver within unbelievable timelines.
We achieve tolerance under +/- 0.2 mm for critical features to ensure proper assembly and fitment.
We use ABS, Nylon and PC-like materials for batch production. Technology and finishing varies across materials. Click here to read about materials.
As their is no fixed cost of tooling, the prices shall be slightly discounted against single piece through 3D printing. Discounted pricing depends on volume. However, get in contact with us to see what can be done for your exact quantity.

Vacuum casting process refers to the production of parts under vacuum using silicon molds. In this technology, a master pattern is made from 3D Printed StereoLithography (SLA) process. A silicon mold is then made from this pattern. The casting medium (molten Plastic or rubber) is then poured in the silicon mold under vacuum. Parts produced using vacuum casting process are dimensionally accurate, and precise replicas of the original pattern with profiles & textures being truly replicated.
No of moulds made out of each pattern can vary from 1-3. For better accuracy, we follow 1 pattern – 1 mould. Each mould is capable of producing 15 components max., before losing its dimensional accuracy.
Vacuum Casting is a slower process than 3D printing. Average lead time for delivery varies from 7-21 working days.
Controlling tolerance in vacuum casting depends on skills of the artist fabricating the product. We achieve tolerance under +/- 0.3 mm for critical features to ensure proper assembly and fitment. Critical features can later be machined / finished manually to achieve tolerance of +/- 0.2 mm or less.
Advantage / Disadvantage
Best process for large plastic parts used for packaging and low stress. VC is highly skilled based process. It is not suitable for highly complex geometries. Also finishing on VC parts is the most time consuming process.

PolyJet 3D printed injection molds are a superior option to evaluate part design and performance. The mold is prepared from Polyjet Technology. These molds are then mounted onto the Injection Molding Machine. The advantage of using Polyjet mold is that, the actual end-use production grade thermoplastic materials can be injected into it. This way organizations can test and evaluate the component which has the actual material properties, as desired, before routing the parts for Mass Production. Parts Manufactured from Polyjet Molds have high resolution and impart good, smooth surface finish.
The process is under development and validation at Chizel House. Stay tuned for further updates.
