麻将在美国走红：华人3D打印工厂在加州Ontario量产整条麻将周边产品线
Ontario——麻将正在美国各地走红，牌桌上用的不少牌具仍靠海运从中国工厂运来；而在加州圣贝纳迪诺县 Ontario 市的一座厂房里，一家由华人经营的 3D 打印公司，把整条美国麻将周边产品线搬上了本地的打印机阵列。这家名为 3D Print Joy 的公司，用 3D 打印生产美国麻将的旅行套装、练习板、推牌板、牌架、骰子盘等近 50 款产品，设计、打印、发货全部在南加州完成。
这条线索来自 GSM 的读者社群。11 月 2 日，GSM 报道美国麻将走红的消息后，美国深圳联合会会员联谊群里一位群友主动现身：他经营的公司正是美国麻将 3D 打印产品的出品方。这位负责人是美国深圳联合会会员，微信昵称就叫「洛杉矶3D打印超级工厂」。他说，这个细分市场「华人基本没人触摸」，没想到 GSM 的文章会「关注到」。
公开资料显示，3D Print Joy 的运营主体为 3D PRINT JOY LLC，对外品牌包括 PlayJoy3D 与工厂品牌 R PLAY FAB，总部与工厂位于 Ontario 市 1990 S Vintage Ave。公司官网介绍，厂房配备工业级 FDM 打印机阵列、24 小时不间断生产，主打无模具、无最低起订量、按单生产，常规订单 3 至 5 个工作日发货；公司同时是拓竹（Bambu Lab）、Polymaker 等 3D 打印品牌的授权合作伙伴。据其在 Thomasnet 的企业页介绍，公司在售产品型号（SKU）超过 800 个，并在美国东西两岸设有仓库；其阿里巴巴供应商页面自称「目前美国最大的 3D 打印超级工厂」，称拥有 10 条以上生产线。
麻将产品是这家公司增长最显眼的品类之一。其 Etsy 官方店铺 3DPrintJoyLTD 共上架 121 件商品，其中美国麻将相关约 47 款：旅行麻将套装、单人练习板、可刻名的推牌板、牌架收纳袋、龙纹骰子盘、洗牌铲等，全部为 3D 打印、从加州发货，店铺累计获得 250 多条买家评价、评分 4.5 星。其阿里巴巴批发页上，麻将练习板以自有品牌「3D NOVA PRINT」出售。据该负责人自述，公司已为原创产品设计申请了 11 项著作权，GSM 此处按其自述呈现。
这轮美国麻将热有数据可查。Yelp 的数据显示，2024 年 9 月至 2025 年 8 月，美国用户搜索「麻将俱乐部」的次数同比增长 4467%，搜索「麻将课程」的次数增长 819%。美国全国公共广播电台（NPR）今年 10 月的报道则追踪到供应链的另一端：一副麻将在江苏泰兴工厂的生产成本约 30 美元，在美国售价可达 300 至 400 美元，畅销款订单排起长队。与泰兴的大批量海运模式不同，Ontario 这家华人公司走的是本地设计、本地打印的柔性生产：改一处设计，当天改完，次日就能打出新的一批。
从牌桌上的热度，到本地工厂里的打印机阵列，这条小供应链的变化，是美国麻将热中一个华人创业的切面。

Mahjong Booms in America: Chinese-Run 3D Print Factory in Ontario, California, Prints a Full Line of American Mahjong Gear
ONTARIO, California — Mahjong is booming across the United States, and most of the gear on American tables still arrives by sea from factories in China. In an industrial unit in Ontario, San Bernardino County, a Chinese-run 3D printing company has put the entire American mahjong accessory line onto its own local printer fleet. The company, 3D Print Joy, 3D-prints nearly 50 American mahjong products — travel sets, practice boards, push boards, racks and dice trays — designing, printing and shipping all of them from Southern California.
The lead came from GSM's own reader community. On November 2, after GSM reported on mahjong's surge in the United States, a member of a U.S. Shenzhen Federation social group stepped forward: his company, he said, is the maker behind a line of 3D-printed American mahjong products. The owner, a member of the U.S. Shenzhen Federation, uses the online handle "Los Angeles 3D Printing Super Factory." This niche, he said, is one that "almost no Chinese makers have touched," and he had not expected GSM's story to notice it.
Public materials identify the business as 3D PRINT JOY LLC, operating under the brands PlayJoy3D and R PLAY FAB, with its headquarters and factory at 1990 S Vintage Ave in Ontario. Its website says the plant runs an industrial FDM printer fleet around the clock, built around no tooling, no minimum order quantities and print-to-order production, with most orders shipping in three to five business days; the company is also an authorized partner and distributor for printer brands including Bambu Lab and Polymaker. Its Thomasnet profile lists more than 800 SKUs in its catalog and warehousing on both U.S. coasts, and its Alibaba supplier page describes it — in its own words — as "currently the largest 3D printing super factory in the United States," with more than 10 production lines.
Mahjong has become one of its most visible product categories. Its official Etsy shop, 3DPrintJoyLTD, lists 121 items, about 47 of them American mahjong products: travel mahjong sets, solo practice boards, personalized push boards, rack storage bags, dragon dice trays and tile shuffling shovels — all 3D printed and shipped from California, with more than 250 buyer reviews averaging 4.5 stars. On Alibaba, its mahjong practice board is sold wholesale under its own brand, 3D NOVA PRINT. The owner says the company has applied for 11 copyrights covering its original product designs; GSM presents that figure here as the company's own account.
The American mahjong boom is measurable. Yelp data shows that from September 2024 to August 2025, U.S. searches for "mahjong clubs" rose 4,467% year over year, while searches for mahjong lessons rose 819%. An NPR report in October traced the other end of the supply chain: a mahjong set that costs about $30 to produce in Taixing, Jiangsu, can sell for $300 to $400 in the United States, with best sellers back-ordered. Against Taixing's high-volume, ocean-freight model, the Ontario company runs on local design and local printing — change a design today, and a new batch can be printed tomorrow.
From the heat around American game tables to the printer arrays in a local factory, the shift along this small supply chain is one Chinese entrepreneur's slice of the American mahjong boom.
