ISO 27547-1:2010规定了使用无模技术制备试样的一般原则。有时，这些技术被称为“无工具”方法。所有这些技术的共同点是，样本是逐层制作的。试样的形状和尺寸通过使用CAD技术的数值描述来定义。通过合适的软件将样本的计算机模型“切片”成层。然后，试样制备过程使用计算机模型和合适的计算机控制激光烧结机，逐层自动构建试样。所使用的三个软件系统（用于CAD、将样本切片成层和机器控制）可以是与机器单独连接的独立系统，也可以与机器集成。ISO 27547的这一部分还规定了通过激光烧结制备热塑性材料试样时应遵循的一般原则。激光烧结工艺用于通过使用激光束的能量烧结热塑性粉末的颗粒来逐层制备样品。ISO 27547的这一部分为建立可重复的烧结条件提供了基础。其目的是促进描述烧结过程主要参数的一致性，并建立报告烧结条件的统一做法。

ISO 27547-1:2010 specifies the general principles of test specimen preparation using mouldless techniques. Sometimes, these techniques are called “tool-less” methods. Common to all these techniques is the fact that the specimens are produced layer by layer. The shape and dimensions of the specimens are defined in terms of a numerical description using CAD techniques. This computer model of the specimen is “sliced” into layers by means of suitable software. The specimen-preparation process then builds up the specimens automatically, layer by layer, using the computer model and a suitable computer-controlled laser-sintering machine. The three software systems used (for CAD, slicing the specimen into layers and machine control) may be independent systems interfacing separately with the machine or they may be integrated with the machine.This part of ISO 27547 also specifies the general principles to be followed when test specimens of thermoplastic materials are prepared by laser sintering. The laser-sintering process is used to prepare specimens layer-wise by sintering the particles of a thermoplastic powder using the energy of a laser beam.This part of ISO 27547 provides a basis for establishing reproducible sintering conditions. Its purpose is to promote uniformity in describing the main parameters of the sintering process and also to establish uniform practice in reporting sintering conditions.
