When the Stratasys Korea team showed him
the benchmark, Park was surprised and pleased
at their solution. The team designed a sample
actuator housing printed with VeroClear™, a
transparent material that simulates hard acrylic. It
offers strength, stiffness, elongation and impact
resistance, and the ability to blend with other
materials for a range of opacities, hues and
hardness. Because of its transparency, VeroClear
enables visualization of internal components and
Conventional manufacturing methods use opaque
materials like metal to make prototypes, including
the housing. This presented a dilemma for the
engineering team at i-Tork: the only way to see
the interior was to cut open the part, rendering the
prototype non-functional. “With VeroClear, we can
see the gear in action, and this would be of great
help to our product development,” Park said.
To solve its manufacturing constraints, i-Tork
introduced a Stratasys 3D printer to its workshop.
The company selected the Objet30 Pro™, which is
ideal for creating high-end prototypes and realistic
models with specialized properties. A desktopfriendly system, the Objet30 Pro provides material
versatility and high accuracy for even the smallest
parts. The roomy tray size made it perfect for
printing large parts for i-Tork’s actuator prototypes.
Its success rate was also much higher than that
of the previous entry-level 3D printer. There was
no more stressing over the need to repeat a job:
operators could start the machine when they left
work and return to a completed part the next
Efficiency Brings Savings
With its high accuracy, the Objet30 Pro greatly simplified the prototyping process. Without the need to communicate with vendors, i-Tork successfully reduced the process from one month to only one week. This meant that engineers and designers had more time to revise and perfect their designs, guaranteeing the high standards that i-Tork consistently seeks. Furthermore, because of the high success rate, the company achieved significant savings in terms of materials and human labor. “In general, it costs approximately KRW 1.5 million ($1,240) to outsource the production of a gearbox prototype. With the Stratasys Objet30 Pro, the maximum cost is KRW 400,000 ($330),” Park said.
