【分析】
做完形填空需先通读全文把握主旨（本文围绕3D打印机这一发明展开，介绍其原理、发展及用途），再逐题结合上下文语境、词义辨析、固定搭配等逐一分析选项，排除不符合逻辑的答案，最终确定正确选项。
【解析】
21. 选A。根据后文“Many great inventions”可知，此处指“小发明”，invention符合语境；story（故事）、lesson（课程）不符合。
22. 选B。后文多次提到“printer”，结合3D打印常识，此处指3D打印机，printer正确；radio（收音机）、camera（相机）与3D打印无关。
23. 选A。句意为“你可能认为它很难用”，suppose（认为）符合；promise（承诺）、forget（忘记）不符合句意。
24. 选B。句意为“文件被发送给打印机”，send的过去分词sent符合被动语态结构；cut（切割）、draw（画）不符合语境。
25. 选A。3D打印常用塑料作为材料，plastic（塑料）正确；frozen（冷冻的）、sticky（粘性的）不符合3D打印材料常识。
26. 选B。句意为“如果设计合适，你几乎能制作任何东西”，suitable（合适的）符合；lively（活泼的）、funny（有趣的）不符合句意。
27. 选A。根据后文“现在越来越多家庭拥有”可知，其发展迅速，rapid（迅速的）正确；slow（慢的）、quiet（安静的）不符合。
28. 选A。句意为“它能在很短时间内完成模型制作的工作”，complete（完成）符合；break（打破）、lose（失去）不符合。
29. 选B。根据后文“普通人负担不起”可知，过去太贵，expensive（昂贵的）正确；heavy（重的）、light（轻的）不符合。
30. 选A。前文说过去贵，现在更便宜，cheaper（更便宜的）符合；higher（更高的）、harder（更难的）不符合。
31. 选B。固定搭配“both...and...”表示“两者都”，此处指家庭和工厂，both正确；neither（两者都不）、all（三者及以上都）不符合搭配。
32. 选B。此处指代“this great invention”，用its（它的）修饰own door，its正确；their（他们的）、our（我们的）不符合指代。
33. 选A。固定搭配“in many fields”表示“在许多领域”，in正确；on、at不符合搭配。
34. 选B。前文讲3D打印机的用途，后文补充医疗领域的应用，besides（此外）符合逻辑；however（然而，表转折）、instead（反而）不符合。
35. 选C。句意为“我们真的相信未来会有更多惊人的发明”，truly（真正地）符合；hardly（几乎不）、nearly（几乎）不符合句意。
