Roland DGA Unveils Its First 3D Printer, New Milling Machine

Roland DGA Corp. has released its first additive 3D printer and a new subtractive milling machine in a product line it calls the monoFab series, the ARM-10 and the SRM-20, respectively. These standalone yet complementary desktop rapid prototyping machines, says Roland DGA, can provide design professionals “the unique ability to combine parts produced by each device for prototypes that integrate the best capabilities of both 3D printing and 3D milling.” The ARM-10 and the SRM-20 are sold separately, according to a company spokesperson.

Roland DGA describes the ARM-10 3D printer as being ideal for design validation in the initial stages of prototyping or modeling. It uses a stereolithography process with a proprietary UV-LED projection system to build models by sequentially curing layers of liquid photopolymer resin. Designers can build complex parts that previously required multi-axis milling, such as hollowing or undercuts, quickly and easily with ARM-10, reports the company.

The ARM-10’s build area is 5.11 (130 mm) W x 2.75 (70 mm) D x 2.75 in. (70 mm) H. X,Y resolution is 0.00079 in. (0.2 mm) and Z-axis resolution is 0.0004 in. (0.01 mm).

The supplied monoFab Player AM (additive manufacturing) software, says Roland DGA, supports 3D printing from STL files and offers a user-friendly interface. Software features include automatic support building, healing and mesh simplification, simulation of resin volume, a preview layer functionality and such controls as change scale, duplicate and rotate. The ARM-10 requires a 1GB workstation running Windows 7 or 8.x operating systems.

The SRM-20 subtractive milling machine can work with a variety of materials, including ABS (acrylonitrile butadiene styrene), acrylic, chemical wood, foam, modeling wax, PC board and polyacetate. Features include a fully-enclosed cabinet, a side window that facilitates viewing milling progress and Z-axis depth, a Y-axis belt drive resistant to the effects of milling debris, and an independent collet system chuck that enables users to replace the collet chuck to match the shank diameter for fast setting of the Z-axis base point as well as quick tool changes.

The SRM-20’s VPanel computer controller panel provides a simple interface for adjusting the tool position and setting the starting point for milling. It also has functionality for controlling feed rates and spindle speed overrides, pause and resume operation as well as tracking X,Y,Z motions. Its numeric readout can display millimeters or inches.

Bundled software with the SRM-20 includes MODELA Player 4 for processing STL files produced by such CAD programs as Autodesk Inventor, Rhino and SolidWorks; iModela Creator for creating and milling shapes, holes, textures and patterns; Virtual MODELA for quick previews of the entire milling operation, including simulation of finished shapes and estimates of production time; and ClickMill, which enables direct control of the SRM-20 for surfacing, drilling holes, cutting pockets and other finishing processes.

The SRM-20 interprets both Roland RML code as well as industry-standard NC code (G-code). It supports a USB interface and runs under Windows operating systems. X, Y, and Z operation strokes are 8 (X) x 6 (Y) x 2.38 (Z) inches – 203.2 (X) x 152.4 (Y) x 60.5 (Z) mm. Work piece table size is 9.14 (X) x 6.17 (Y) inches – 232.2 (X) x 156.6 (Y) mm. Mechanical resolution is 0.0000393 in./step (0.000998594 mm/step). The spindle rotation speed is adjustable from 3,000 to 7,000 rpm.

“The monoFab series desktop fabrication tools are the culmination of over 25 years of experience in 3D milling,” said Rachel Hammer, 3D product manager for Roland DGA, in a press statement. “By combining the capabilities of these advanced rapid prototyping machines, users can select the best method for their workflow, from concept to production. Now, designers have greater opportunities to turn their ideas into reality.”

The list price for the ARM-10 desktop 3D printer is $6,995. The SRM-20 subtractive milling machine list price is $4,995. For more information about the monoFab series of rapid prototyping machines, visit Roland DGA.
