To provide an additive-manufactured product assembly which can be manufactured at a low cost while enjoying advantages of additive manufacturing technology.SOLUTION: A heat exchanger T comprises: a heat exchange part 10 being an additive-manufactured product formed by additive manufacturing that fuses deposited metal powder; and an upstream-side gas conduit 21 being a non-additive-manufactured product made of metal formed by a method different from additive manufacturing. The heat exchanger is structured by assembling the heat exchange part 10 and the upstream-side gas conduit 21. The heat exchanger T comprises an abutment part 40A at which the heat exchange part 10 and the upstream-side gas conduit 21 abut on each other, and a fixing part 50A at which the heat exchange part 10 and the upstream-side gas conduit 21 are fixed to each other at the same position as the abutment part 40A. In the abutment part 40A, a thickness of the heat exchange part 10 as an additive-manufactured product is smaller than a thickness of the upstream-side gas conduit 21 as a non-additive-manufactured product.SELECTED DRAWING: Figure 2 【課題】積層造形技術の利点を享受しつつ、低コストで製造することができる積層造形物組立体を提供する。【解決手段】熱交換器Ｔは、積層した金属粉末を溶融する積層造形によって形成された積層造形物である熱交換部１０と、積層造形とは異なる方法で形成された金属製の非積層造形物である上流側ガス管路２１と、を備え、熱交換部１０と上流側ガス管路２１とを組み立てることで構成される。熱交換器Ｔは、熱交換部１０と上流側ガス管路２１とが当接する当接部４０Ａと、当接部４０Ａと同じ位置で熱交換部１０と上流側ガス管路２１とが固定される固定部５０Ａと、を備える。当接部４０Ａにおいて、積層造形物である熱交換部１０の厚さは、非積層造形物である上流側ガス管路２１の厚さよりも薄い。【選択図】図２
