Overview
Sindoh is a South Korean office-equipment and 3D-printing company headquartered in Seoul. Established on July 7, 1960, as Sindoh Trading Co., Ltd., it began by developing and manufacturing copying and document-processing equipment for the Korean market. The company changed its name to Sindoh Co., Ltd. in 1969 after entering a partnership with Japan’s Ricoh, a relationship reflected in the company’s former name, Sindoricoh. That partnership helped Sindoh participate in the early development of Korea’s office-machine industry and contributed to the production of several products described by the company as national or market firsts. Sindoh’s historical business has centered on two-dimensional document equipment. Its portfolio has included monochrome and color multifunction printers in A3 and A4 formats, standalone printers, copiers, fax machines, and related consumables such as thermal fax paper. The company’s early milestones included production of the RICOPY555 copier in 1964, the BS-1 electronic copying machine in 1969, the DT1200 plain-paper copier in 1975, and the FAX3300H facsimile machine in 1981. It later developed its own copier technology, including the FT-1000 launched in 1991. In 2008, Sindoh introduced managed printing services intended to help organizations control document-management and equipment-maintenance costs. The company expanded its manufacturing footprint outside South Korea during the 2000s and 2010s. It opened operations at a first Qingdao factory in China in 2003 and a second Qingdao factory in 2006. It subsequently established Sindoh VINA Headquarters in Vietnam as a Southeast Asian production base in 2014, followed by Sindoh VINA Marketing as a regional sales base in 2015 and a second Vietnamese factory in 2017. Its two-dimensional printer business has been associated primarily with South Korea, while the company’s 3D-printer business has pursued international markets, particularly the United States and Europe. Sindoh entered 3D printing under the 3DWOX brand in 2016 with the DP200 and DP201. The DP200 was positioned as an approachable machine for users with limited prior 3D-printing experience. The company subsequently broadened its range with the 3DWOX 2X prosumer printer, 3DWOX 1 and 1X models, and the large-format 3DWOX 7X. Sindoh also worked with Dassault Systèmes SolidWorks on software integration that allowed users to print from a CAD environment without relying on a separate slicer workflow, and participated in the Apps for Kids initiative to make cloud-enabled 3D printing more accessible to children. Its additive-manufacturing portfolio later extended beyond fused-filament fabrication. Sindoh introduced the A1 and A1+ SLA machines in 2019, the S100 selective laser sintering system in 2020, and the A1SD masked stereolithography and LCD printer in 2021. In 2022, it introduced the fabWeaver type A530, a newer FFF platform. Across its businesses, Sindoh presents itself as a technology-focused supplier spanning office document workflows and additive manufacturing rather than as a consumer lifestyle brand. The company renewed its corporate identity in 2013 as part of an effort to strengthen the Sindoh name.
History
Sindoh was founded on July 7, 1960, under the name Sindoh Trading Co., Ltd. Its early development took place during the formation of South Korea’s domestic office-equipment industry. In 1964, the company produced the RICOPY555, identified in reference material as Korea’s first copier. In 1969, it entered a partnership with Japan’s Ricoh and changed its name to Sindoh Co., Ltd.; the company was also known for the former Sindoricoh name. In the same year, it produced the BS-1, described as Korea’s first electronic copying machine. Sindoh expanded its physical and technical infrastructure during the 1970s and 1980s. Its Seoul head-office construction in Seongsu-dong was completed in 1971. In 1975, it produced the DT1200, described as Korea’s first plain-paper copier. The company followed with the FAX3300H facsimile machine in 1981 and began producing thermal paper for fax applications in 1982. It completed construction of an Asan factory in 1983 and developed high-sensitivity thermal fax paper in 1990. In 1991, Sindoh launched the FT-1000 copier using its own technology, marking a further move toward internally developed products. The company began building an overseas manufacturing network in the 2000s. Operations at its first Qingdao factory in China began in 2003, followed by a second Qingdao factory in 2006. Sindoh also broadened its service proposition beyond hardware. In 2008, it introduced managed printing services designed to optimize corporate printing environments and reduce document-management and maintenance costs. In 2013, it renewed its corporate identity to reinforce the Sindoh brand. During the 2010s, Sindoh established a stronger Southeast Asian presence. Sindoh VINA Headquarters began operating in 2014 as a production base, while Sindoh VINA Marketing began operating in 2015 as a regional sales base. A second Vietnamese factory followed in 2017. The company also started communicating more directly with international audiences, launching an official international YouTube channel in 2017. A major strategic development was Sindoh’s move into additive manufacturing. It launched the 3DWOX DP200 and DP201 in 2016, with the DP200 intended to make 3D printing approachable for inexperienced users. In collaboration with SolidWorks, Sindoh introduced software enabling users to send models to a 3D printer from a CAD program without a separate slicer workflow. In 2017, the companies also developed an Apps for Kids program intended to make cloud-based 3D printing easier for children. Sindoh launched the 3DWOX 2X that year as a prosumer product. The range continued to expand. Sindoh introduced the 3DWOX 1 in 2018, the 3DWOX 1X and the A1/A1+ SLA printers in 2019, and the large-output 3DWOX 7X in the same year. It launched the S100, described as its first SLS printer, in 2020 and the A1SD, an MSLA and LCD machine, in 2021. In 2022, it introduced the fabWeaver type A530, a newer FFF platform. Sindoh therefore developed from a Korean copier and fax-equipment producer into a broader office-imaging and 3D-printing manufacturer with Korean, Chinese, Vietnamese, and international market operations.
