The complex world of watches has been digitally transformed: 3D printing tourbillon breakthrough
For centuries, mechanical watches have symbolized human creativity. At its peak, the tourbillon was a fascinating complication of Abraham-Louis Breguet’s invention in 1795. This rotating cage counteracts the impact of gravity on watch escape and enhances the accuracy of the pocket watch. However, making traditional tourbillons requires unparalleled skills. It took hundreds of hours to arduously assemble up to 100 micro-assemblies, each group requiring submicron accuracy. result? Beautiful timepiece, but usually with five or six figure price tags and limited accessibility.
Input Additive Manufacturing – A revolution quietly transforms impossible designs into tangible reality. In a landmark leap, Huangbilon successfully printed 3D printing, removing decades of manufacturing restrictions. This is not a conceptual prototype. This is through Metal additive manufacturing. meaning? How we conceive, create and democratize the earthquake transitions of mechanical miracles.
Breakthrough: How 3D printing reshapes the wingspan
The core of this innovation is Selective laser melting (SLM). Unlike subtraction methods such as CNC milling, SLM builds components layer by layer from metal powder and fuses with precise laser accuracy. For Tourbillons, this means:
-
No compromise on complexity:
Traditional approaches relate to the nested geometry of the tourbillon – think about the rotating cage inside the cage, ultra-thin gears and hollow bearings. SLM prints them as a single, unified structure or pre-assembled subunit, eliminating assembly errors and material stress. -
Material flexibility:
From aviation-grade titanium to biocompatible stainless steel or nickel superalloys, the SLM can accommodate metals that are impossible to drive on a regular basis. These materials provide excellent strength-to-weight ratios, reduce inertia and improve timing stability. -
Large-scale accuracy:
With resolutions reaching 20-30 microns, SLM achieves a crucial ±5 micron tolerance. Iterative prototyping (not possible with traditional tools) allows for rapid optimization of weight distribution and aerodynamics. - Integrated Driver Design:
Engineers embed features such as lubrication channels or weight-reducing lattices directly into the assembly. A groundbreaking example? A 3D printed tourbillon cage with gyro-stabilized fins optimizes rotation efficiency without manual modification.

FAQ: 3D printed tourbillon and metal additive manufacturing
Q1: Can 3D printed Tourbillons match the accuracy of traditional tourbillons?
Absolutely. When optimized by SLM and post-processed, they can achieve timing accuracy (±4 seconds/day). Reduced printed parts quality often enhances rotational stability.
Q2: Which metals are suitable for 3D printing tourbillons?
Titanium alloy (TI64), 316 liters of stainless steel and cobalt powder are popular for strength/weight balance. Greatlight also provides support for extreme environments and custom Maraging Steels.
Q3: How does SLM compare to SLS or DML of metal parts?
SLMs fully melt the powder by laser to form denser (>99.5%), stronger parts are ideal for dynamic mechanisms. SLS/DMLS sintered particles, leaving microscopic pores, and are not suitable for high pressure components such as Escapements.
Q4: Do 3D printing metal parts really require post-processing steps?
Critical. Supports removal, stress relief annealing and surface finishes (e.g. polishing, coating) ensure dimensional accuracy and prevent corrosion. Greatlight’s integrated services ensure production-ready quality.
Question 5: Can I order a custom flash prototype without my tabulation expertise?
Yes. Greatlight collaborates at each stage: CAD optimization, material selection, printing and completion. Share your concept; their engineers deal with the rest.
Question 6: What tolerances can be achieved for micro components?
SLM printing can hold ±0.02–0.05mm. After being combined, they can achieve key interfaces such as jewellery bearings such as ±0.005mm (±5 microns).
Question 7: How cost-effective is the production of complex parts in small batches through SLM?
Unlike the tool weight method, SLM has no upfront mold costs. Each set is priced significantly lower at ~50+ units, making it ideal for limited editions or feature prototypes.
