Wire-based steel printing
Steel wire is melted and deposited layer by layer to form near-net-shape parts. The approach suits medium to large components, uses material efficiently and removes the need for heavy tooling.
AI-Powered Digital Twin Steel Printing
Steel additive manufacturing,
engineered by intelligence.
Joyest pairs wire-based metal 3D printing with a live digital twin and AI, so every layer is simulated, monitored and optimized before and while it is built.
- Wire-fed steel deposition
- Physics-based digital twin
- Closed-loop AI control
Who we are
A new way to make large steel parts: faster to plan, smarter to build.
Joyest is a Vietnam-based deep-tech startup applying artificial intelligence and digital twin technology to wire-based steel additive manufacturing. We turn a CAD model into a verified, high-quality metal part by predicting how the process will behave, then guiding the printer in real time.
Our goal is to make metal 3D printing predictable, repeatable and economical for industries that depend on large, durable steel components.
Technology
Three technologies, one intelligent workflow
Each part of the stack strengthens the others, from the wire feedstock to the data that improves the next build.
Digital twin
A virtual replica of the part, process and machine predicts heat build-up, distortion and defects before printing starts, then stays synchronized with the real build as it happens.
AI process optimization
Machine-learning models tune deposition parameters and toolpaths for quality, speed and cost, and learn from every build to make the next one better.
How it works
From CAD file to certified part, in a closed loop
Our workflow keeps the digital and physical worlds connected at every step.
- 01
Model & simulate
Import the CAD design and simulate thermal history, distortion and toolpaths inside the digital twin.
- 02
Optimize with AI
AI tunes current, wire feed, travel speed and interpass temperature, and plans the best deposition strategy.
- 03
Print under control
Sensors stream melt-pool, temperature and geometry data. The twin compares it with predictions and corrects in real time.
- 04
Verify & learn
As-built results are compared with the design. Every build becomes training data for the next.
Real-time process monitoring
Sensing the melt pool layer by layer keeps the physical build aligned with its digital twin.
Why Joyest
Built for quality, speed and design freedom
- Predict before you print. Virtual build trials reduce failed prints and costly trial and error.
- Repeatable quality. Closed-loop control keeps each build consistent from part to part.
- Less material, shorter lead time. Near-net-shape parts need less machining and no dedicated tooling.
- Design freedom. Produce complex, optimized geometries that are hard to cast or forge.
- Continuous improvement. Every build adds data that improves the AI models.
Where data meets molten steel.
Joyest turns process data into better metal parts, connecting simulation, sensing and control into a single intelligent manufacturing loop.
