ST Dispenser: Home recycling of soap products
CT3D partnered with ST Dispenser to transform a patent-pending idea into a high-fidelity demonstration unit. The goal: show investors and licensees how a wall-mounted or free-standing appliance could recycle bar-soap remnants into fresh liquid soap. The key difference between CT3D and other product development companies is that with CT3D, you are in the driver’s seat. Take a look at our process:
Concept Design
When the project started, all the customer had was a patent application drawing of the core features of the device. CT3D kicked off the project by using AI-generated concept art to explore exterior form factors quickly. Instead of jumping straight into CAD, we mocked up multiple wall-mounted and countertop silhouettes, UI layouts, and color treatments. This gave ST Dispenser’s team a set of “what-if” visuals to react to before anyone spent hours modeling.
Rapid Prototype & Customer Feedback
Once the look/feel was narrowed down, we moved into CAD and physical prototyping. CT3D’s workflows let us iterate quickly: we split the housing into modules, 3D printed shell revisions, and reviewed them with the client via in-person sessions, virtual meetings, and sectioned renderings. Each cycle refined user ergonomics, soap-handling subsystems, and manufacturing feasibility.
Internal Module Architecture
We engineered the interior exactly like a functional unit: hopper and grinding mechanism for bar soap remnants, reservoirs for additives, metered plumbing, mixing chambers, heating element, and a holding tank for finished liquid soap. Even though the deliverable was a non-functional showpiece, every subsystem was represented physically so investors and licensees could understand the process flow instantly.
Finished Demonstration Prototype
With the internal layout locked-in, we focused on the exterior surfaces. The final model featured a high-fidelity outer shell, tactile controls, indicator lighting, and detachable panels to expose the internal modules. We delivered the assembled showpiece alongside high-resolution photography, sectional CAD renders, and a complete drawing package so ST Dispenser could use it for marketing, demos, and future manufacturing conversations.
In the end, ST Dispenser walked away with more than a showpiece—they gained a tangible proof of concept, a manufacturing-ready CAD package, and a visual story to anchor investor conversations. By blending AI-driven ideation, hands-on prototyping, and thoughtful interior architecture, CT3D turned a complex soap-recycling concept into a compelling physical product that’s ready for its next stage of commercialization.
