COSL Issues Tender for Metal 3D Printing SLM Systems — Industrial-Grade AM Procurement for Downhole Tool R&D

2026-08-05 · Impact score: 28

On August 4, 2026, China Oilfield Services Limited (COSL, Oilfield Production Division) issued a procurement tender for metal 3D printing system equipment (Project No.: 26-CNCCC-HW-GK-3123), intended for the R&D of key completion tools for SAGD balanced injection-production in heavy oil thermal recovery — specifically the fabrication of critical tools such as FCD valves with complex flow channels. The tender requires laser powder bed fusion (SLM) technology, with a delivery lead time of 180 days. Only direct bids from manufacturers are accepted (agents and traders are not eligible). Bidders must hold ISO9001, ISO14001, and ISO45001 certifications and have at least one supply track record of metal 3D printing systems since 2023. Background: Chinese oil majors have previously ventured into additive manufacturing — PetroChina successfully trial-produced an ultra-large SLM logging tool probe in 2021, and in 2026, PetroChina's Kunlun Capital made a sole multi-hundred-million-yuan equity investment in Zhongke Yuchen to bolster AM capabilities. COSL's dedicated industrial-grade metal SLM tender for production-oriented R&D remains rare among petroleum central enterprises, signaling the substantive penetration of additive manufacturing from aerospace/medical into the oil & gas drilling and completion sector. Industry significance: The oil & gas sector represents a blue ocean market for AM. Downhole tools operate under extreme conditions (high temperature, high pressure, corrosive media), and conventional manufacturing struggles with complex flow channels — SLM is a natural fit. As the largest oilfield services provider under CNOOC, COSL's pioneering procurement carries strong supply-chain demonstration effects, and oilfield services subsidiaries under PetroChina and Sinopec may follow suit. Value for powder suppliers: Oil & gas completion tools open a new downstream market for IN718, IN625, and 17-4PH powders. Powder demand in the oil & gas industry features concentrated grades (dominated by nickel-based alloys), large volumes, but lengthy certification cycles — suppliers that complete oilfield service customer certifications early will secure a first-mover advantage.

中海油服发布金属3D打印SLM系统招标——工业级AM专项采购用于井下工具研发

2026年8月4日，中海油田服务股份有限公司（油生事业部）发布金属3D打印系统设备采购招标（项目编号：26-CNCCC-HW-GK-3123），用于稠油热采SAGD均衡注采关键完井工具研制科研项目——制造复杂流道FCD阀等关键工具。要求金属粉末激光选区熔融（SLM）工艺，交货期180天，仅接受制造商直投（不接受代理商/贸易商），投标人需具备ISO9001/ISO14001/ISO45001三体系认证及2023年以来至少1个金属3D打印系统供货业绩。背景：石油央企此前已有AM布局——中石油2021年成功试制SLM超大尺寸测井仪探头，2026年中石油昆仑资本独家直投数亿元入股中科煜宸布局增材制造。中海油服此次以工业级金属SLM系统专项招标用于生产型科研项目，在石油央企中仍属少见，标志着增材制造从航空/医疗向油气钻完井领域的实质性渗透。行业意义：油气行业是增材制造的蓝海市场。井下工具工况极端（高温高压+腐蚀介质），传统制造复杂流道困难，SLM工艺天然适配。中海油服作为中海油旗下最大油田服务商带头采购，具有强烈的产业链示范效应，后续中石油、中石化旗下油服公司可能跟进。对粉末采购商的价值：油气完井工具打开了IN718/IN625/17-4PH粉末的新下游。油气行业粉末需求特点是牌号集中（镍基合金为主）、量大但认证周期长，率先完成油服客户认证的粉末供应商将获得先发壁垒。

NAMI Secures GAMI Military Manufacturing License in Saudi Arabia, Signaling the Start of the Middle East AM Powder Market

On August 3, 2026, NAMI (National Additive Manufacturing & Innovation), a joint venture between 3D Systems and Saudi Dussur, received certification from Saudi Arabia's General Authority for Military Industries (GAMI), becoming the first AM company in the country qualified for military manufacturing. NAMI will produce 3D-printed military components locally, directly supporting the defense localization goals of Vision 2030. 3D Systems' metal AM business posted double-digit growth in Q2, and the GAMI certification further unlocks the Middle Eastern defense market. This marks the region's first step from zero to one in military AM, driving regional demand for aerospace-grade powders such as Ti64, IN718, and CoCrMo. Saudi Vision 2030 targets over 50% localization of military manufacturing, and NAMI, as 3D Systems' exclusive JV in the region, is poised to become a major consumer of AM powders in the Middle East. Industry significance: The Middle East is one of the largest arms procurement markets globally, yet AM powder demand has been nearly nonexistent. NAMI's GAMI certification signals the region's official entry into metal AM-based defense manufacturing. Dussur, backed by Saudi sovereign wealth, provides long-term capital and order security, creating a bipolar landscape alongside the U.S. military AM ecosystem. For powder buyers, the Middle Eastern defense powder market is starting from scratch, offering first-mover suppliers the chance to secure exclusive supply agreements. Ti64 and IN718 are the preferred grades for defense applications, and suppliers with AS9100/NADCAP certifications will benefit the most.

Hiroshima University Develops Hot-Wire Laser WC-Co Tungsten Carbide Coating with Hardness Exceeding 1400 HV

On August 1, 2026, a research team at Hiroshima University unveiled a hot-wire laser cladding technology for depositing WC-Co tungsten carbide coatings, achieving a hardness exceeding 1400 HV—comparable to conventional cemented carbides and significantly higher than standard laser-clad WC-Co coatings (around 1100 HV)—while also delivering more uniform WC particle distribution. The approach combines a heated wire (which preheats the substrate to reduce residual stress) with laser cladding (for precise energy control), addressing the long-standing issue of cracking in WC-Co deposition. WC-Co coatings are essential wear-resistant materials for molds, cutting tools, and mining machinery, representing a multi-billion-dollar global market. Industry significance: surpassing 1400 HV in WC-Co coating hardness marks the first time AM-produced coatings have matched the performance of traditional sintered cemented carbides. The hot-wire-assisted method resolves the persistent cracking problem in laser cladding of hard materials, opening a viable technical pathway for transitioning WC-Co from sintering to additive manufacturing. For powder buyers, if this technology scales from lab to production, it would generate new demand for spherical WC-Co powder (used in LPBF). While the current WC-Co powder market is niche, its high unit price ($80–150/kg) means that a technological breakthrough could substantially drive demand growth.

Lohia Aerospace Signs MoU with Israel's Massivit, Invests $8-10M to Build Large-Format Composite 3D Printing Facility in India

On August 4, 2026, India's Lohia Aerospace Systems signed a Memorandum of Understanding (MoU) with Israel's Massivit 3D Printing Technologies to establish a joint manufacturing alliance, bringing large-format additive manufacturing technology to India for the first time. Lohia plans to invest US$8-10 million to deploy 8-10 Massivit RapidWings printers at a new 250,000-square-foot facility in Kanpur. Massivit's Cast-In-Motion (CIM) technology enables the production of aerospace composite molds within days—compared to weeks with traditional methods—cutting lead times by up to 90% and reducing costs by up to 50%. Each mold costs approximately US$10,000-20,000, and each printer can produce 1-2 complete molds per day. Lohia holds exclusive rights for the Indian aerospace and defense sectors, covering UAVs and manned aircraft, with the strategic goal of achieving 100% import substitution for molds, in line with India's Make in India and Atmanirbhar Bharat initiatives. Industry significance: India's aerospace AM market has long relied on imported tooling. The Lohia-Massivit partnership marks a shift from part-level to tooling- and mold-level domestic aerospace additive manufacturing. Although large-format composite AM is not within the metal powder segment, the localization of aerospace tooling will indirectly drive overall capacity expansion in India's aerospace manufacturing sector, creating a market foundation for future metal AM powder demand. Value for powder buyers: This project involves composite AM and does not directly drive metal powder demand. However, as the world's fifth-largest economy, India's accelerated aerospace manufacturing autonomy implies potential medium-to-long-term growth in demand for metal AM powders (titanium and nickel-based alloys). Lohia holds AS9100D and NADCAP certifications, and should it enter the metal AM space, it would become a significant buyer in the Indian market.
