Much of the design study was concerned with a simple, flexible chemical system for processing lunar regolith, and the differences between the ratio of elements needed by the replicator, and the ratios available in regolith.  The limiting element was Chlorine, an essential element to process regolith for Aluminium.  Chlorine is very rare in lunar regolith, and a substantially faster rate of reproduction could be assured by importing modest amounts.

大部分的设计研究都是关于一个简单、灵活的化学系统来处理月球表面的风化层,以及复制因子所需要的元素比率和风化层中可用的比率之间的差异。限制元素是氯,一个必不可少的元素处理风化层的铝。氯在月球的风化层中非常罕见,通过进口适量的氯,可以保证更快的生殖速度。

A "casting robot" would use a robotic arm with a few sculpting tools to make plaster molds.  Plaster molds are easy to make, and make precise parts with good surface finishes.  The robot would then cast most of the parts either from non-conductive molten rock (basalt) or purified metals.  An electric oven melted the materials.

These systems are substantially simpler than autotrophic systems, because they are provided with purified feedstocks and energy.  They do not have to reproduce them. This distinction is at the root of some of the controversy about whether molecular manufacturing is possible or not.  Many authorities who find it impossible are clearly citing sources for complex autotrophic self-replicating systems.  Many of the authorities who find it possible are clearly citing sources for much simpler self-assembling systems, which have been demonstrated.  In the meantime, a Lego-built autonomous robot able to follow a pre-set track and assemble an exact copy of itself, starting from four externally provided components, was demonstrated experimentally in 2003 [http://www.MolecularAssembler.com/KSRM/3.23.4.htm].

这些系统比自养系统简单得多,因为它们提供了纯化的原料和能源。他们不需要复制它们。这种区别是关于分子制造是否可行的一些争论的根源。许多当局认为这是不可能的,他们明确地引用了复杂的自养自我复制系统的资源。许多发现这种可能性的权威人士显然是在引用已经证明的更简单的自组装系统的资料。与此同时,2003年的一项实验展示了一个乐高积木自主机器人,它能够按照预先设定的轨道,从外部提供的4个组件开始,精确地组装出自己的副本。 Molecularassembler.com/ksrm/3.23.4.htm.

In 2011, New York University scientists have developed artificial structures that can self-replicate, a process that has the potential to yield new types of materials.  They have demonstrated that it is possible to replicate not just molecules like cellular DNA or RNA, but discrete structures that could in principle assume many different shapes, have many different functional features, and be associated with many different types of chemical species.
