Abstract(J)これまでSKD61ダイス鋼粉末での造形は割れやすく実用化が困難だといわれてきた、3D 造形用に成分を調整したSKD61 系粉末を使用して世界初,密度99.996~8 で造形できる割れない造形条件を確立した。本稿では、MAMS造形の応用例として、ハイブリッド造形ダイカスト金型部品での量産適用を行った事例や、ダイカスト金型における金属3D プリンティング技術活用の取組みを紹介する。

Abstract(E)The typical problems in the aluminum die-casting process, such as reduced cycle times and mold seizing, can be solved by modern additive manufacturing techniques that is able to add intricate cooling channels to locate proximity of the mold surface. That can also enable the reduction of environmental impact by anti-seizing compounds. This article reports the successful development of diecasting mold manufacturing by AM with using one of the most common die-casting steels in Japan called SKD61.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
