Moreover, the OPM250L and the OPM350L come prepared for integration with the Internet of Things (IoT) to allow unmanned and automated production at the manufacturing site. Designed to permit remote operation, the system significantly reduces labor costs by streamlining the production process.
Sodick Group is committed to expanding its core technologies for all processes to offer one-stop solutions, following our tradition of “Creating What We Cannot Find in the World.”

One Stop Solution

Sodick proudly introduces practical one-stop metal 3D printing solutions.

An one-stop solution of
a practicing precision metal 3D printer is proposed.

The OPM Series precision metal 3D printers allow us to offer an industry-leading “onestop solution.”
Sodick provides integrated support for all processes, from design to molding, through its extensive technologies, including wire-cut electrical discharge machines, die-sinker electrical discharge machines, injection molding machines, and machining centers.
Performing laser sintering and high-speed milling on the same machine permits the machining of complex molds with a degree of freedom and high-precision finishing that is simply impossible with conventional cutting tools.


Precision Metal 3D Printer

The OPM Series performs continuous laser machining and high-speed milling in a single machine.A uniform layer of metal powder is melted and solidified through direct metal laser sintering.
Thisis then precision machined by high-speed milling to create a high-quality shape not attainable through additive manufacturing alone.

Injection Molding Machine

Injection Molding Machine

Sodick employs the V-LINE® system that separates the plasticization and injection processes. Adopting the proprietary V-LINE® system allows the development of a zero-backflow system. After weighing, the flowis actively cut off before the injection operation is performed, so that all weighed resin is injected into the mold. The introduction of the V-LINE® system brings about accurate filling volumes for more stable molding.

Machining Center

Machining Center

In addition to our proven linear motor and high-speed milling technologies, the UH Series offers practical machining simulation software and an ergonomic, curved design. Through full linear motor operation, Sodick machining centers achieve high-speed, highprecision, high-quality machining.


Die-Sinker EDM

The new “Arc-less Plus” electrical discharge machining system is installed standard, lowering overall costs and human errors by substantially shortening machining times and reducing the number of electrodes required. Moreover, the SVC circuit rapidly creates high- quality satin or mirror surfaces.

Wire EDM

Wire EDM

Smart Pulse electrical discharge technology and a proprietary direct tension servo mechanism accomplish both high-speed and high-precision machining for unparalleled performance. Additionally, the FJ-AWT high-speed automatic wire threader incorporates a wire straightening function, enabling high wire threading rates.
The result is reduced work hours and long-term, unmanned operation.

High Power Laser High Speed Milling

Additive Manufacturing with Sodick’s precision Metal 3D Printer

The OPM Series is an automated machine that melts and solidifies a uniform layer of metal powder in a process called laser sintering. The machines then engage in high-speed milling for highly accurate finishing. Sodick proudly achieves metal 3D printing through the use of a 500W fiber laser for the melting and solidifying metal powder.

The OPM Series features a 45000 min-1 spindle that achieves high-speed and high-precision machining with Sodick’s non-contact rigid linear motor drives.
An automatic tool changer (ATC) and automatic tool length measuring device are installed to allow continuous automated operation over a long period of time.



After each layer is fully machined, the workspace is recoated with metal powder and the process is repeated.

Linear Motors

Sodick employs high-performance linear motors developed and manufactured by Sodick, replacing ball screw drives with a reliable direct drive system.
These linear motors indefinitely maintain backlash-free, accurate axis movements, which is impossible with conventional ball screw drive systems. A space-saving machine layout design is achieved by arranging the drive axes for high-speed milling and laser machining in a compact structure.

High-Speed Cutting

Sodick has fostered a line of high-speed, high-accuracy cutting technology over the years using high-speed milling center developed in-house. The OPM Series permits stable finishing for a wide range of applications by integrating proven machining expertise with this high-speed milling center.

High-Speed Cutting

Chamber Technology

Sodick is an expert in vacuum chamber design, with over 10 years of production experience.
First designed in 2003, Sodick’s vacuum chamber technology has been tested in the PF00A/PF32A Electron Beam PIKA Finish EBM, with great success. By maintaining a high concentration of inert gas, Sodick’s vacuum chamber achieves stable and accurate laser sintering.

Mold Internet of Things (IoT)

Mold Internet of Things (IoT)

Unmanned and Automated Control, Remote Operation

The expertise of experienced engineers was indispensable for conventional mold manufacturing, which required complex processes, numerous parts, and multiple machine tools. Today, however, the OPM Series may be the only machines that encompasses a full production system to manufacture high-density, finished molds with one-piece construction. With high-quality mold data, the OPM Series allows for unmanned manufacture of highquality molds anywhere. It is easy to create a “Mold Internet of Things” to control production from a remote design department.
The result is automation with reduced lead times, lower costs, and significant labor savings. In this way, the manufacture of uniform quality products in any location can be achieved.

Security Measures

Sodick NC units apply the following security measures to the network connections.

LN4RP power supplies offer :
• System protection with the FBWF (File-Based Write Filter) function
• Prohibited execution of files other than CNC system files;
• Data communication between power supply and external PC using FTP;
• Prohibits connections, except to Sodick-certified USB memory

High-Quality Machining to Create Mold IoT

Mold manufacture requires a high sintered density (99.9% melting ratio) and highly accurate machining. The OPM Series meets both criteria, permitting finishing (SPI-A2 class) not possible with a conventional metal 3D printer.

High-Quality Machining to Create Mold IoT

Test Machining to Check Accuracy

Required precision of ±1/100 mm in maraging steel All shapes were achieved.

OPM Series: Plastic Molding Revolution

Molding Revolution

When plastic products are injection molded, the molding performance is significantly affected by the construction of the mold used.
Temperature control inside the mold is always a critical element in this aspect.The OPM Series can produce molds with 3D cooling channels freely positioned inside, eliminating uneven temperatures within the mold.
It allows an ultra-high cycle rate that was impossible with a conventional mold and permits optimization of the molding shrinkage. As a bonus, these process improvements reduce the lead time by half or more.

Uniform, high-quality production control (mold IoT) from a remote location

High-precision machining of freely configured, one-piece molds

Moldex3D plastic injection molding simulation software (Core Tech System Co., Ltd.) permits the 3D arrangement of cooling channels which can normally be arranged in two dimensions only. It also performs simulation of molded products during injection molding.
Side-by-side comparisons with conventional molds confirm that deformation is lower with the 3D cooling channels.

Conventional mold: 2D cooling channels
  • ●Deformation must be estimated for mold production.
  • ●The estimated deformation may result in a reverse gradient in the direction of product withdrawal.
  • ●A slide mechanism may be required in the mold construction.
OPM mold: 3D cooling channels
  • ●As a 3D arrangement of cooling channels is possible, molds can be produced without estimating the deformation. A one-piece mold can be produced instead of a divided mold.
  • ●Mold production is simple, as no slide mechanism is required in the mold construction.

Reduced total costs

Shorter lead times

Suppresses the deformation of the molded products by allowing conventional split molds to be made as one piece, achieving an optimal cooling channel arrangement that was not possible with conventional machine tools.
