Roland DGA.

Roland DG Corporation's profile lists the founding date as 1 May 1981 and the headquarters as 1-1-2 Shinmiyakoda, Hamana-ku, Hamamatsu, Shizuoka 431-2103, Japan, telephone +81-53-484-1200. The representative on that page is Kohei Tanabe. The corporate timeline says the firm began as AMDEK, a Roland Corporation subsidiary in Osaka, and took the Roland DG name in 1983. A US subsidiary, Roland DGA Corporation, is dated 1990.

The same timeline says the first DWX dental milling machine was released in 2010. In 2017 Roland DG transferred the 3D business to a wholly owned subsidiary, DGSHAPE Corporation, to focus staff on dental and other 3D products. DGSHAPE's about page says Roland DG entered dental milling in 2010 because its XYZ motion-control experience could help laboratories, and that DGSHAPE now sells those mills to laboratories and intends to extend them to clinics.

DGSHAPE describes the current DWX lineup as four dry mills plus one wet mill for glass ceramics. It cites desktop size and open architecture with common CAD software and scanners. An Australian Roland DG timeline names earlier models, including the DWX-30 in 2010, the five-axis DWX-50 in 2011, the DWX-4 in 2013, and the first wet mill, DWX-4W, in 2015. Treat that list as history unless the current DGSHAPE page still shows the model.

The parent company still lists dental milling machines and dental 3D printers among main products on the corporate profile. A dental purchase can therefore be a mill, a printer, or both. They are different devices. The catalog website used on this site is the US Roland DGA address, while the machines' corporate home is Hamamatsu. The corporate profile also lists wide-format inkjet printers and vinyl cutters, which are the company's sign-making business, not dental mills. A dental lab should not receive a sign printer when the purchase order says DWX. ISO 9001 is dated 1999 on the corporate timeline. That certificate is a quality-system mark, not a milling accuracy number. Paid-in capital on the corporate profile is 10 million yen, and the headquarters fax is +81-53-484-1227. Capital is not a measure of how many mills the plant can ship. DGSHAPE's about page says the wet mill is aimed at glass ceramics, a material it says clinics and patients have adopted for hardness and appearance. That is the manufacturer's reason for offering a wet machine.

DGSHAPE suits a laboratory that wants a desktop mill with open CAD software rather than a closed scanner-and-mill bundle. Compare mills on the milling machine guide.

Printers are a separate category. See the dental 3D printer guide.

Roland DG is the Hamamatsu parent, founded in 1981, and still known for wide-format printers and cutters. DGSHAPE is the 2017 subsidiary that holds the dental and 3D milling business. A dental invoice may use either name. The mill manual should say DGSHAPE or Roland DG on the cover.

A 2010 DWX-30 is not the machine in a 2026 quote. Ask for the current dry or wet model number.

Specify dry or wet, the materials, the CAM software, and who installs the mill. The Hamamatsu telephone is +81-53-484-1200. US buyers should also ask Roland DGA which warehouse supports the serial number.

Open architecture still needs a written compatibility list. Do not assume every intraoral scanner drives every DWX.
