How Museum-Grade Dinosaur Skeleton Replicas Are Made

It begins with a reference, not a mould

A replica is only as faithful as its reference. Production starts with measured scans or a licensed cast of the original specimen, plus photographs and published descriptions that fix proportions. Skipping this step produces a skeleton that looks plausible and is anatomically wrong, which museums notice immediately.

Mould making is the hidden cost

Each bone needs a mould that releases cleanly and survives repeated pulls. Large elements are split into sections with registration keys so the seams disappear after assembly. Mould quality decides how much finishing work is needed later, and finishing is where most of the labour sits.

Casting material follows the job

Resin casts hold fine surface detail and suit study or handling collections. Fiberglass is lighter and stronger for large mounted elements, which matters when a skeleton is suspended or travels. Many projects mix the two: resin for teeth and small bones, fiberglass for long limb elements and ribs.

Finishing decides the read

Colour is a decision, not a default. A study cast often keeps a neutral, readable tone, while a display cast may be patinated to suggest age. Either way, the finish should be consistent across bones, because variation between pieces reads as damage rather than character.

Assembly and documentation

The last stage is the one most often skipped: a bone map, an assembly sequence and a record of which elements are replicas. Institutions need that documentation for conservation and for future repair. A good supplier hands it over without being asked.

DinoCG produces skeleton replicas for museum and touring exhibitions, and matches the casting method to whether the piece will be studied, displayed or shipped.

从参考开始，而不是从模具开始

复制品的保真度取决于参考。生产从原始标本的测量扫描或授权翻模开始，再加上照片和已发表的形态描述来固定比例。跳过这一步，会得到一副看着合理、解剖却错误的骨架，博物馆一眼就能看出来。

模具是隐形成本

每块骨骼都需要一副能顺利脱模、可重复翻制的模具。大型构件要分段并做定位键，拼接后接缝才能消失。模具质量决定后道修整的工作量，而修整正是人工最集中的环节。

材料跟着用途走

树脂能保留细腻表面，适合研究用或可上手接触的藏品。玻璃钢更轻更强，适合大型悬挂或需要运输的装架构件。很多项目会把两者混用：牙齿和小骨用树脂，长骨和肋骨用玻璃钢。

表面处理决定观感

颜色是决策，不是默认值。研究用复制品通常保持中性、易读的色调，展陈用复制品可能做旧以暗示年代。无论哪种，各骨骼之间的表面处理必须一致，否则差异会被读成破损而不是质感。

装配与文档

最后一步最常被忽略：骨骼图谱、装配顺序，以及哪些构件是复制品的记录。机构需要这些资料用于保护和日后维修。可靠的供应方会主动交付，不需要追问。

DinoCG 为博物馆和巡展项目生产骨架复制品，并按用途是研究、展陈还是运输来匹配翻制方式。
