Subtractive rapid prototyping with high speed CNC milling machines from DATRON that fature a 60,000 RPM spindle for fast cycle times and superior surface finish.

Rapid Prototyping


With additive manufacturing and 3D printers being such a hot topic these days, it's important to remember why subtractive processes like machining are still incredibly important to rapid prototyping. First, subtractive rapid prototyping provides the ability to prototype in end-use materials. Since milling or machining removes material from a larger piece of material, the finished part is comprised of a solid piece rather than in layers typical to additive rapid prototyping with 3D printers. This delivers a higher structural integrity which is critical if the prototype part is to be used in product or market testing. Subtractive rapid prototyping processes like milling also offer a wider range of surface finishes for the finish prototype as opposed to the standard "stepped finish" often achieved in additive rapid prototyping with a 3D printer. Subtractive rapid prototyping with a high speed CNC milling machine produces prototype parts with a repeatability suitable for end-use manufacture. Here are some DATRON high speed machining center features that benefit the subtractive rapid prototyping process:


  • High Speed Spindles (up to 60,000 RPM) - The high spindle speed reduces the chip load which reduces the forces between the tool and the material. High-speed/low-force machining yields less heat, reduces tool deflection, and allows machining of thinner walled work pieces. This all results in cooler machining, superior surface quality and better accuracy.
  • Spray-Mist Coolant System - The spray-mist coolant system minimizes the time consuming and expensive maintenance issues associated with flood-type coolant systems. It is a highly-effective method of cooling and can reduce or even eliminate degreasing and disposal costs.
  • Probing / Surface Scanning - scans surface, recognizes irregular work-piece topography and compensates for it dynamically
  • Automatic Tool Changer - up to 45 tool stations depending on machine model, includes tool-length and breakage detection
  • Vacuum Table Workholding - vacuum tables from 12" x 18" up to 24" x 36" provide quick setup of sheet material
  • Pneumatic Clamping Systems - pneumatic, shortstroke clamps that minimize setup times for redundant processes
  • 5-Axis Capability - integrated trunnion-style rotary axis for multisided milling of aluminum (watch video)

Milling Machines for Rapid Prototyping:
While all DATRON milling machines are designed for use in rapid prototyping as well as production environments, there are some differentiators that may help you to narrow your search. The M8Cube offers an ample 40" x 32" work area for milling prototypes. Using our PerfectCut filter this machine will produce prototypes with exceptional surface finish.

For milling prototypes that are a bit larger or require the highest quality surface finish, the M10Pro is best suited. This is our fastest and most precise CNC machining center. It features a 41" x 35" bed with high position accuracy. Its solid granite machining table adds rigidity and accuracy. HSK-25E tool holders yield less than 1 micron runout. All of this adds up to mirror-like surface finishes.

Now, if an extremely large work area is required, as is the case when milling a batch of prototype parts or a very large prototype part, the MLCube features a 60" x 40" work area. This can also benefit manufacturers who wish to batch machine production runs once the prototype is prove out. Due to features like automatic tool change, batch machining can be run unattended or during lights-out production as a means of cost reduction.
