テーブルトップRPG（TTRPG）の世界で今、3Dプリントされたミニチュアフィギュアが爆発的に売れているんです。D&Dを筆頭に、Warhammer・Pathfinderなどのプレイヤー人口が世界規模で増えている中、「自分だけのキャラクターフィギュア」への需要が供給を大きく上回っているとのこと。

Redditの「r/PrintedMinis」（登録者20万人超）では、光造形（レジン）プリンターで出力したミニチュアの完成度の高さに驚く投稿が日常的に話題になっています。

In the world of tabletop RPGs (TTRPGs), 3D-printed miniature figures are experiencing an explosive boom. With the global player base for D&D, Warhammer, Pathfinder, and other games growing, the demand for "my own character figure" far exceeds the supply.

On Reddit's r/PrintedMinis (over 200,000 subscribers), posts showcasing the astonishing quality of miniatures produced with resin (SLA) printers routinely go viral.

Kickstarterで1億円を集めたケース

スペインのクリエイターチーム「Loot Studios」は、月額制のSTLファイル配信サービスをKickstarterで立ち上げ、初回キャンペーンで約80万ドル（約1.2億円）を達成したんです。毎月テーマに沿ったミニチュアのデータが届いて、自分でプリントして使う仕組みなんです。

STLデータを売る形式なら在庫を抱えるリスクがないし、プリント品質はユーザー側の機材次第。作る側にとって理にかなったビジネスモデルなんですよ。

光造形プリンターが主役

ミニチュアフィギュアにはFDMより光造形（SLA/MSLA）プリンターが向いています。細部の再現性が段違いで、髪の毛や装備の彫り込みまで出てくるんです。Elegoo MarsやAnycubic Photonなら3〜5万円台から始められます。

A Case That Raised 100 Million Yen on Kickstarter

The Spanish creator team "Loot Studios" launched a monthly STL file subscription service on Kickstarter, achieving approximately $800,000 (about 120 million yen) in their initial campaign. They deliver themed 3D data sets of miniatures every month, with participation starting from $10 per month. They boast an impressive retention rate with a churn rate of only 8%.

What makes this model clever is that it holds no physical inventory whatsoever. Since it's purely digital data distribution, the marginal cost is almost zero. It can scale infinitely.

How Individual Creators Can Enter the Market

The classic route is to sculpt character models using ZBrush or Blender and sell them on MyMiniFactory (a marketplace specializing in miniatures) or Gumroad. The price range for a single STL file is $3 to $8. For sets (10-figure packs), the market price is typically $20 to $40.

Of course, even those who "can't model" can enter as a print-on-demand service. They can purchase STL data, print it with an Elegoo Mars 4 Ultra or Anycubic Photon Mono M7, paint it, and sell it as a finished product. The market price for a single painted miniature is $15 to $50. While it's labor-intensive, the high unit price makes it viable even with small quantities.

Potential in the Japanese Market

While the TTRPG population in Japan is still small, the Warhammer community is rapidly growing. Furthermore, there's a huge adjacent market of diorama enthusiasts and figure collectors. Custom parts for 1/35 military figures and 1/12 dollhouses represent a strong, unique demand in Japan.
