Our proficiency in 3D modeling enables us to use all sorts of rapid prototyping technologies to deliver your desired level of accuracy from study models to consumer testing mock-ups to final prototypes - in either rigid or soft materials.
If you want to know more about the different rapid prototype processes please feel free to read through these short explanations:
CNC block models:
CNC Milling used for machining complex parts and shapes hard to machine with conventional machines. The cutter path is generated directly from the CAD model, which is transferred to machine controller in the form of numerical data. This data is used to move the machine table and tool to create the high precision jobs.
Use when mechanical properties can not be compromised with any additive RP process.
FDM, also known as Fused Deposition Modeling is layered manufacturing process. FDM offers functional prototypes with ABS, and other materials. A thin bead of molten plastic is extruded through the computer controlled nozzle, which is deposited on a layer-by-layer basis to construct a prototype directly from 3D CAD data. The technology is commonly applied to form, fit and function analysis and concept visualisation. In addition, FDM can be used for pattern generation and rapid manufacturing.
Good combination of strength and surface finish at affordable price and lead time.
SLA, also known as Stereolithography, provides the greatest accuracy with an excellent surface finish. Process works by curing liquid photopolymers when exposed to ultraviolet light. SLA is limited in its range of applicable materials but still widely used for conceptual designs, Product verification, Pattern making, Form/Fit analysis and light functional testing.
Excellent surface finish suitable for presentation, master models and light functional testing.
SLS also known as Selective Laser Sintering, primarily used to quickly produce three dimensional parts, layer by layer, from powdered materials. The CO2 Laser provides a concentrated heating which welds (sinters) the powder within a precisely controlled chamber. SLS has distinctive advantage of having wide variety of materials that can be suitable for functional analysis.
Range of materials available, soft like rubber to strong like metal. SLS Nylon suitable for snap and living hinge features
Objet's PolyJet technology works by jetting state of the art photopolymer materials in ultra-thin layers of 16 µm or 30 µm onto a build tray layer by layer until the part is complete.
The high resolution of the print head and the small layer thickness enable the creation of models that meet a wide range of form, fit, and function requirements utilizing a wide variety of both rigid and flexible materials.
3DP also known as 3D printing works on FDM principle as a layered manufacturing process. 3DP offers prototypes with thermoplastic Polyester material. A thin bead of molten plastic is extruded through the computer controlled nozzle, which is deposited on a layer-by-layer basis to construct a prototype directly from 3D CAD data. The technology is commonly applied to initial conceptual design. In addition, parts can be used for form fit and light testing purpose.
Suitable for general purpose parts for initial design stage with a quick delivery.
VC (Vacuum Casting) is widely used process in rapid prototyping industry, typically used for making 20 to 40 pieces of functional prototypes out of broad range of polyurethanes and other polymers available. The process starts with creation of an accurate and highly finished master model which can be created using various RP techniques e.g. SLA, FDM, SLS, CNC or existing part. This model is carefully placed in a mold box and liquid silicon rubber is poured over the master. After curing the silicon, mould is cut as per split line established and master model is removed, leaving an accurately formed cavities. Now these mould cavities are used to cast large variety of polyurethane or epoxy materials available. This allows fast production of high quality parts in a short lead time. A broad range of polyurethanes with various physical properties enable the production of prototypes to more closely mimic the functional properties of engineering thermoplastics.
