The Design and Rapid Prototyping Instrumentation Project for Technology Teacher Education at Ball State University puts high-tech design equipment in the hands of tomorrow's technology teachers. As technology education evolves from industrial arts, there is an increasing emphasis on teaching secondary school students about technological design. Unfortunately, technology students and teachers often have experiences only with outdated and inefficient hardware and software design tools. The objective of this project is to give undergraduates in technology education experiences with advanced tools for technological design. These teachers of tomorrow will then be better equipped to help their students achieve in this area. Undergraduates in Ball State's Technology Teacher Education Program have added experiences from this project in both two- and three-dimensional design at two different stations. At Station 1, they input an existing design with a page scanner, from a file, or using design or drafting software. The design is then manipulated as needed. One of the output devices at this station is a laser cutting machine, where students cut out these designs from appropriate materials, such as 1/4-inch acrylic and wood. At a Station 2, the students use a three-dimensional laser scanner to input the surface coordinates of existing objects. They then manipulate this design data to suit the needs of their project. The output can be an illustration, or files that could be used with an existing numerically controlled milling machine or an existing fused deposition modeling machine to create a prototype.

波尔州立大学的技术教师教育设计和快速原型仪器项目将高科技设计设备交到未来的技术教师手中。随着技术教育从工艺艺术演变而来，越来越重视对中学生的技术设计教学。不幸的是，技术专业的学生和教师通常只有过时和低效的硬件和软件设计工具的经验。本计画的目的，是让科技教育的本科生，在科技设计方面有先进的工具。这些未来的教师将更好地帮助他们的学生在这方面取得成就。波尔州立大学技术教师教育项目的本科生从这个项目中获得了在两个不同的站点进行二维和三维设计的经验。在第1站，他们用网页扫描器、从文件或使用设计或绘图软件输入现有的设计。然后根据需要对设计进行操作。这个工作站的输出设备之一是激光切割机，学生们可以从合适的材料上切割出这些设计，比如1/4英寸的丙烯酸和木材。在第二站，学生们使用三维激光扫描仪输入现有物体的表面坐标。然后他们操纵这些设计数据以适应他们项目的需要。输出可以是插图，也可以是文件，可以与现有的数控铣床或现有的熔融沉积成型机一起使用，以创建原型。
