    Vacuum Casting provides high-quality parts production at low- to mid-volumes without the cost and time of hard tooling, using 3D printed masters and silicone moulds that defy traditional production timelines.

    Key Features: Wide range of polyurethane materials, smooth surfaces, colours available with RAL or Pantone number.

    From product development models and prototypes to low-volume production runs, this rapid prototyping process allows us to produce parts that accurately mimic the colour, texture, feel and physical properties of injection moulded parts.

    • Accurately mimic production colours and textures
    • Large material selection – rigid, flexible, durable, transparent and high-temp
    • Offers similar physical properties to injection moulded parts
    • Used for pre-production runs
    • Parts made for marketing samples and test prototypes
    • Low-volume manufacturing

    Cast Urethane parts can be completed and delivered in days after completing SRM tooling (Silicone Rubber Molds). Short runs of several hundred pieces can be delivered within weeks in most instances.

    One of the most significant benefits of the Cast Urethane process is the ability to over-mould existing parts or hardware with a second material.

    Fused Deposition Modeling

    CNC Machining

    Build parts in final production materials

    CNC refers to cutting material with a computer numerical control machine. The CNC machining process interprets your 3D CAD model and translates data to CNC machines. The main benefit of the process is that CNC will produce parts that can replace the additive manufactured prototypes with production grade materials. This method allows you to build your parts in the featured material that you intend for use in production. CNC machining is the best choice for rapid prototyping of high-quality metal and plastic parts requiring the highest degree of dimensional accuracy, critical surface finishes, material-specific properties.

    Whether for rapid prototypes or production parts, we have the right CNC machining options for your metal and plastic part needs.

    • Wide range of materials
    • Ability to hold tight tolerances
    • Parts machined directly from 3D CAD models
    • Standard delivery time of 1-2 weeks based on an order
    • Shorter lead time (2-5 business days) available per open capacity

    Tolerances for feature size:

    • Standard +/- .005
    • Minimum +/- .002 for metal and +/- .003 for plastic

    Tolerances for hole diameter:

    • Standard +/- .005
    • Minimum +/- .001 for metal and +/- .002 for plastic

    Tolerances for Flatness, Run Out, Cylindricity, Perpendicularity, and other Geometry:

    • Standard +/- .005
    • Minimum +/- .001 is possible per geometry dependent

    The tolerances above will not apply when machining a weldment, or a plate below 1/4″ thick at length above 20″ or 1/8″ thickness at length exceeding 10″ long. In that case the tolerances need to be reviewed by the MFG team.

    Investment Casting Patterns

    Accelerate your casting production timelines with high quality, fast prototype and production casting patterns with 3D Technology On Demand Manufacturing services

    Investment casting, often known as lost-wax casting, is a manufacturing methodology that has been around for thousands of years. While there has been some degree of automation in the foundry industry, the need for the pattern around which to make the cast shape remains a constant – and waiting for tooling to create the patterns can take weeks or months, costing tens to hundreds of thousands of dollars.

    3D printed casting patterns offer a tool-free, fast, reliable and accurate alternative to patterns created using tooling, reducing the costs of creating a pattern by as much as 90%, and produced in one-tenth of the time. With two key 3D printing materials – SLA plastic and wax – that are fully industry-tested, your casting patterns can be completed in days or a couple of weeks, with little to no restriction on the size of the casted part.

    3D Technology On-Demand Manufacturing offers rapid production of casting patterns from its partner production facilities in the UK. With expert teams who have been producing investment casting patterns for more than 20 years, using additive platforms and materials that are being continually refined and updated to meet ever more rigorous standards, On Demand Manufacturing can meet your needs for prototype and production-grade casting patterns.

    3D printed patterns can be created quickly, and deliver more complex parts than injection moulded wax patterns. We use both a plastic process and a wax process depending on the needs and applications of our customers.

    SLA Cast Patterns

    The SLA Cast build style consists of a hollow SLA pattern with an internal hexagonal support structure that adds strength to the pattern, allows for easy drainage, and facilitates collapse of the pattern during thermal expansion to help avoid shell cracking. SLA Cast patterns offer invaluable shrink and gating information before hard tooling, large pattern size, smooth surfaces, and accelerated timelines over tooling to create wax patterns.

    • Hollow build style reduces the amount of material to burn out
    • Commonly used by the casting industry
    • Capable of producing large assemblies
    • Highly stable CastPro™ resins developed specifically for foundry applications
    • Rapid production compared to traditional tooling
    • Provides invaluable shrink and gating information before hard tooling
    • Low moisture absorption and expansion of the pattern
