Five Parts. Five Manufacturing Problems. One Platform.

Seals and gaskets sample kit by Inkbit, is shipped with five physical parts. Each one addresses a specific failure mode in conventional sealing component manufacturing.

Tooling introduces draft angles that alter cross-sectional geometry in the sealing zone. Overmolding requires secondary bonding operations that add variance. Multi-material requirements get resolved by splitting a single component into an assembly, which introduces tolerance stacking at every interface. The design team knows what the part needs to do. The manufacturing process determines what the part actually does.

That gap between what the design requires and what the process allows is where product performance gets negotiated away. Most teams accept it. They shouldn't have to.

Vision-Controlled Jetting does not use tooling. Material is deposited voxel by voxel under closed-loop machine vision feedback, which means geometry is held to the CAD file regardless of whether a feature is structural, sealing, or both. The sample kit was built to demonstrate that difference on five specific problems.

Intake Duct

Integrated Sealing Features in Complex Geometry

Standard practice for ducting assemblies: manufacture the duct, add a sealing element at each interface.

Intake Duct, printed using TEPU™ 50A an Inkbit elastomer material. The flexible TEPU duct with integrated ridges for airtight sealing in complex, custom fluidic geometries.

The Intake Duct in the kit eliminates the sealing element entirely. Sealing ridges are integrated directly into the duct wall, printed in TEPU 50A as part of the geometry. There is no secondary component. There is no bonding step. There is no interface to misalign.

The implication for multi-interface fluidic assemblies is direct. Every junction that currently requires its own gasket, its own alignment, and its own inspection step can be consolidated into the duct geometry. The sealing performance is determined by the CAD. Not the assembly.

Edge Seal

Custom Profiles Without Custom Tooling

Standard elastomeric profiles are defined by what tooling can produce. O-rings, D-rings, square section seals. The catalog exists because those geometries are manufacturable at scale, not because they are optimal for any given application.

Edge Seal, printed using TEPU 50A an Inkbit elastomer material. Custom cavities and tight radii for specialized sealing beyond traditional extrusion limits.

The Edge Seal in the kit is a continuous elastomeric profile with a geometry tuned to its sealing interface. It is printed in TEPU 50A. There is no tooling. There is no minimum order. The profile can be modified between iterations without capital expenditure.

For applications where the sealing geometry should be derived from the interface requirement rather than the tooling constraint, this changes the design process significantly.

Port Cover

Multi-Material in a Single Part

A component with a rigid mounting structure and a compliant sealing face has two material requirements. Conventional manufacturing resolves this by producing two components and joining them. The joining step introduces its own tolerance, its own bond strength variability, and its own failure mode.

Port Cover, printed using TEPU 50A + Titan Tough 85. Elastomer + rigid multi-material door port delivering structural strength with integrated airtight sealing for exposed environments.

The Port Cover is a single printed part. Titan Tough 85 provides the rigid substrate. TEPU 50A provides the compliant sealing face. Material transition is defined in the print. There is no adhesive. There is no secondary assembly operation. There is no bond to test.

The geometry in this kit includes an automotive charge port application. The principle applies to any cover or cap where the mounting interface requires rigidity and the sealing face requires compliance.

"The pattern holds across all five parts. What used to require two components, a joining operation, and an inspection step gets resolved in the print. The Gasket section is where that argument is hardest to make with conventional tooling."

Gasket

Functional Geometry Without Overmolding

Overmolded gaskets require the elastomeric material to bond chemically or mechanically to the substrate during the overmold cycle. The bond is the failure point. Bond strength varies with surface preparation, cycle parameters, and material lot. The gasket geometry is also constrained by what the tool can fill and eject.

Gasket printed in Titan Tough 85 and TEPU 50A elastomer. A multi-material gasket combining rigid internals and TEPU overmold for durable sealing with soft-touch interface.

The Gasket in the kit is printed as a single-pour multi-material part. Titan Tough 85 provides the structural carrier. TEPU 50A provides the elastomeric sealing surface. There is no bond. The material interface is defined by the print. Sealing geometry, including channels, variable section profiles, and integrated retention features, is not constrained by a tool.

For gaskets that currently fail at the bond interface, or that require a geometry the overmold tool cannot produce, this is the relevant comparison.

K-Cube

Print-in-Place Mechanism

The K-Cube is not a sealing component. It is a fully articulated mechanism printed as a single part with no assembly.

Inkbit’s famous multi-material fidget cube showing unique capabilities. The part including it’s moving elements printed as a single piece.

It is in the kit because the underlying capability is directly relevant to sealing system design. Any mechanism that currently requires assembly to function, a valve, a pressure relief element, a latch on an access cover, accumulates tolerance at every assembled interface. Print-in-place eliminates that accumulation. The mechanism tolerances are set in the print file.

The K-Cube demonstrates that a moving element inside a closed housing can be produced without assembly. The application in a sealing system is whatever the design requires.
