三井化学株式会社（本社：東京都中央区、代表取締役社長：橋本修、以下「三井化学」）と三井化学の子会社である株式会社アーク（本社：大阪府大阪市、代表取締役社長：両角直樹、以下「アーク」）は、2社で共同開発したダイレクトペレット式3Dプリンティング部品^※1と、三井化学が開発した一方向性炭素繊維強化ポリプロピレン樹脂シート「TAFNEXCF/PP」^※2が、TCD ASIA CO.,LTD.^※3（タイ・バンコク、代表取締役社長：河副貴之、「以下、TCD-A」）が企画したTOYOTA FORTUNERをベースにした高機能コンセプトカー「TOYOTA Hyper-F CONCEPT」に搭載されたことをお知らせいたします。

TAFNEXCF/PPおよび今回開発したダイレクトペレット式3Dプリンティング部品は、タイ・バンコクにて6月26日から6月30日に開催されるカスタムカーショー「バンコクオートサロン2024」、タイ・バンコク近郊にて7月3日から7月7日に開催されるカーレース「バーンセングランプリ2024」で展示されます。

TAFNEXCF/PPおよび3Dプリンティング部品が搭載されたTOYOTA Hyper-F CONCEPT

「TOYOTA Hyper-F CONCEPT」は、TCD-Aのモータースポーツ事業におけるレーシングフィールドで培った走破性能、空力性能を踏まえたスタイリングデザインを採用した高機能コンセプトモデルです。新素材の活用により、更なる軽量化も実現しました。スポーツシートを4座配置することで、2シーターでは味わえない新しい愉しみ方を創造します。

今回、TAFNEXCF/PPはフードエアダクト、フロントバンパーの一部に加飾部品として、ダイレクトペレット式3Dプリンティング部品はフードエアダクトのベゼル（枠）部品に搭載されています。

※1　ダイレクトペレット式3Dプリンティング部品について

三井化学は、2020年に自動車開発におけるESP（エンジニアリングサービスプロバイダー）であるドリームスデザイン株式会社（本社：愛知県名古屋市、代表取締役：奥村康之）、2023年にダイレクトペレット式3Dプリンターメーカーである株式会社ExtraBold（本社：東京都豊島区、代表者：原雄司）に出資・業務提携を開始しました。

今回搭載された3Dプリンティング部品は、ドリームスデザイン社の車両部品の設計技術、ExtraBold社の大型・高速造形が可能な3Dプリンター「EXF-12」、試作から量産までの製品開発⽀援企業で業界国内最⼤⼿であるアークの３Dプリンターの造形・後加工技術、そして三井化学で3Dプリンティング向けに開発を進めるポリオレフィン系コンポジットの技術を総動員し、実現しました。

ダイレクトペレット式の3Dプリンターは、射出成形用の機構を応用して樹脂ペレットから直接造形することで、従来型３Dプリンターよりも樹脂の吐出量を安定的に増加させ、大型の造形物を高速で造形できるメリットがあります。また、3Dプリンティングによる多品種少量生産での型レス工法は、「開発期間の短縮」や「金型コスト等の初期投資の削減」に寄与します。さらに、造形物を粉砕してペレットを造粒することで3Dプリンター造形原料としてリサイクルできるため、サーキュラーエコノミーへの貢献も期待できます。

※2　TAFNEXCF/PPについて

TAFNEXCF/PPは、三井化学独自の技術を用いて炭素繊維とポリプロピレン（PP）を複合化した一方向性テープ（UDテープ）です。軽量、高剛性で成型性が良く、大理石調デザインなど多彩に意匠を変えられる特徴を持っています。射出成型品やプレス加工品への部分補強としての用途展開や、パイプ形状、積層板計上への加工が可能で、自動車、ドローン、産業・民生向けの各種用途分野への適応、採用を目指しています。

(headquarters: Chuo-ku, Tokyo; President and CEO: Osamu Hashimoto; hereinafter referred to as 'Mitsui Chemicals') and its subsidiary, Ark Corporation (headquarters: Osaka City, Osaka Prefecture; President and CEO: Naoki Ryo Kakudo; hereinafter referred to as 'Ark'), jointly developed direct pellet-type 3D printing parts.^※1TAFNEX CF/PP, a unidirectional carbon fiber reinforced polypropylene resin sheet developed by Mitsui Chemicals, andthe direct pellet-type 3D printing parts developed this time will be exhibited at the Bangkok Auto Salon 2024 custom car show, which will be held from June 26th to June 30th in Bangkok, Thailand, and at the Burn Seng Grand Prix 2024 car race, which will be held from July 3rd to July 7th near Bangkok, Thailand.^※2We are pleased to announce that TCD ASIA CO., LTD. (Bangkok, Thailand; President and CEO: Taka Yukiyuki Kawasugi; hereinafter referred to as 'TCD-A') has installed the developed TAFNEX CF/PP and 3D printing parts on the high-performance concept car 'TOYOTA Hyper-F CONCEPT', which is based on the TOYOTA FORTUNER planned by TCD-A.^※3TAFNEX CF/PP and the direct pellet-type 3D printing parts will be mounted on the food air ducts and some of the front bumper of the car.

TAFNEX CF/PP and the direct pellet-type 3D printing parts will be exhibited at the Bangkok Auto Salon 2024 custom car show, which will be held from June 26th to June 30th in Bangkok, Thailand, and at the Burn Seng Grand Prix 2024 car race, which will be held from July 3rd to July 7th near Bangkok, Thailand.CF/PP and the direct pellet-type 3D printing parts developed this time will be exhibited at the Custom Car Show "Bangkok Auto Salon 2024" held in Bangkok, Thailand from June 26th to June 30th, and the car race "Burn Sang Grand Prix 2024" held in the vicinity of Bangkok, Thailand from July 3rd to July 7th.

The TOYOTA Hyper-F CONCEPT is a high-performance concept model that features a styling design that incorporates off-road performance and aerodynamic performance cultivated in TCD-A's motorsports business. Utilizing new materials has enabled further weight reduction. By placing sports seats in four seats, it creates a new way of enjoying that cannot be experienced in a two-seater.

TAFNEX CF/PP and the direct pellet-type 3D printing parts were installed on the TOYOTA Hyper-F CONCEPT.

TCD-A began investing and promoting business partnerships with DreamsDesign Co., Ltd. (headquarters: Nagoya City, Aichi Prefecture; CEO: Yasuyuki Okumura) in 2020 and ExtraBold Co., Ltd. (headquarters: Toshima-ku, Tokyo; representative: Yuji Hara), a direct pellet-type 3D printer manufacturer, in 2023, both of which are ESP (engineering service providers) for automotive development. The 3D printing parts mounted this time were realized by mobilizing the design technology of Dreams Design's vehicle parts, Extra Bold's large and fast-forming 3D printer 'EXF-12', Ark's 3D printer formation/post-processing technology, which is the largest industry supporter of prototype to mass-produced product development, and Mitsui Chemical's polyolefin-based composite technology developed for 3D printing.

TAFNEX CF/PP was used as a decorative part for the food air duct and a part of the front bumper.CF/PP is used as decorative parts for the hood air duct and front bumper, while the direct pellet-type 3D printing parts are installed on the bezel (frame) parts of the hood air duct.

*1 About direct pellet-type 3D printing parts

In 2020, Mitsui Chemicals began investing and promoting business partnerships with Dreams Design Co., Ltd. (headquarters: Nagoya City, Aichi Prefecture; CEO: Yasuyuki Okumura), which is an ESP in automotive development, and in 2023, with ExtraBold Co., Ltd. (headquarters: Toshima-ku, Tokyo; representative: Yuji Hara), which is a direct pellet-type 3D printer manufacturer. The development part this time was realized by mobilizing Dreams Design's vehicle parts design technology, Extra Bold's large and fast-forming 3D printer 'EXF-12', Ark's 3D printer formation/post-processing technology, and Mitsui Chemical's polyolefin-based composite technology developed for 3D printing.

The direct pellet-type 3D printer uses the mechanism for injection molding to directly form shapes from resin pellets, providing benefits of increasing the amount of resin extruded more stably than conventional 3D printers and allowing for high-speed formation of large objects. In addition, the moldless method of multiple variations and small-lot production by 3D printing contributes to shortening development periods and reducing initial investments such as die costs. Furthermore, the waste of the molded object is ground to granulate the pellet for recycle as a 3D printer molding material, contributing to the circular economy.

※2 TAFNEXCF/PP TAFNEX CF/PP is a unidirectional tape (UD tape) that combines carbon fiber and polypropylene (PP) using Mitsui Chemicals' proprietary technology. It is lightweight and rigid with good formability, and has the ability to change its design, such as a marble-like pattern. It can be used for partial reinforcement of injection molded or pressed products, as well as for processing into pipe shapes and laminated panels. It aims to be adopted for various industrial and civilian applications such as automobiles, drones, etc. ※3 TCD ASIA CO., LTD. is a subsidiary of Toyota Customizing & Development Co., Ltd. based in Thailand.
