Review the process and model
We establish the tooling purpose, dimensions, allowances, parting lines, draft, tolerances and surface requirements.
Industrial tooling
3D-printed and CNC-machined master patterns
We print a large near-net blank with machining allowance, then CNC-machine it to the agreed geometry. The master is used to make moulds, tools and production patterns.

A master pattern, mould and production tool are different stages
A master pattern reproduces the original positive geometry. A working negative mould or tool is then made from it for casting or forming. Printing builds the large volume quickly; machining establishes interfaces and the required surface.
In some processes the printed part can be used directly as tooling, but only after engineering review. Temperature, vacuum, pressure, chemical compatibility, cycle count and surface requirements determine the material, structure and finishing route.
From a digital model to a production master
Print a near-net blank
Large-format pellet FGF printing creates a shape close to final geometry with a controlled machining allowance.
CNC-machine the surface
We remove the allowance, establish datum surfaces and machine the geometry to the parameters agreed before production.
Prepare the next production stage
The master is ready for the sealing, coating and mould-making steps defined by the project. The exact scope is stated in the quotation.
Processes supported by master patterns
These are typical routes. For every project we first review the working medium, temperature, pressure, release method and required tool life.
Rigid and flexible PU foam
Masters for moulds used to cast rigid or flexible polyurethane foam, accounting for expansion, venting, parting and demoulding.
Glass- and carbon-fibre composites
Master patterns and moulds for hand lay-up, vacuum infusion and other agreed processes. Vacuum and cure temperature must be specified in the brief.
Rubber-crumb products
Masters for production moulds for tiles, landscape elements and other products. Pressure, heat, release system and planned cycle count are reviewed in advance.
Concrete and architectural castings
Patterns for flexible or composite moulds used for panels, reliefs, décor and small architectural concrete forms.
Plaster and cast stone
Master patterns for moulds used to make plaster décor, panels, three-dimensional elements and short production runs.
Vacuum forming
Positive tools and masters for thermoforming plastic sheet. Draft, working temperature and vacuum channels or perforation must be engineered.
Epoxy systems
Tooling and masters for epoxy casting, with the exotherm, casting thickness, sealing and release system checked for each project.
Silicone moulds and parts
A master can be used to make a silicone mould. Casting silicone parts requires a separately designed rigid tool and parting system.
Moulded fibre and papier-mâché
Patterns for moulded-fibre and papier-mâché products. Production tooling for moulded pulp needs a separate screen, drainage and vacuum design.
Further applications to assess
These uses are technically related to hybrid printing and machining, but are accepted only after reviewing the production requirements.
Foundry patterns
Large patterns and segments for sand moulds, allowing for foundry draft, machining allowance and the customer's material shrinkage.
Templates and factory tooling
Assembly, inspection and trimming templates, nests and complex holding fixtures for production environments.
Direct printed tooling
Low-temperature moulds and vacuum tools without an intermediate master, subject to material, sealing and load validation.
What we need to quote
The better the downstream production process is defined, the more reliably we can choose the blank structure, machining allowance and CNC scope.
- A 3D model or drawing of the original part
- Dimensions, datum surfaces and parting lines
- Tolerances, surface requirement and final coating
- What will be made from the master and by which process
- Temperature, pressure, vacuum and working chemicals
- Planned quantity and required mould cycle count
Scope agreed before production
A printed master pattern is not automatically a production-ready mould. The quotation separately states the material, machining allowance, machined sides, tolerances, sealing, coating and responsibility for the final mould.
Send us your tooling brief
Describe the end product and the process that needs the master. Attach a 3D model, drawing or reference and include dimensions, mould material, temperature and planned quantity when known.
Projects start at RUB 50,000.
Timing and scope are confirmed after reviewing the geometry and tooling requirements.
