raw material. Several cases of rough surface of FDM products have been documented. Figure 3(a) shows that the slanted (or curved) surfaces of FDM products can be ragged due to the size of plastic filament that forms the layers. Figure 3(b) shows a different problem. The component of an air filtration system (senior design, fall 2011), which should be perfectly circular, came out with small edges that affected the airflow. It was caused by a low resolution setting when the students translated the CAD model into STL format (commonly used by RP machines). The STL format uses triangular mesh to approximate 3D designs. With a low resolution, the STL file is compact, but the approximation of curvatures can be

, materials, printer set up, pre- and post-processing of the following technologies were covered. a. Stereolithography (SLA) process involves curing or solidifying a photosensitive polymer resin in a vet by light beam (ultraviolet laser). The 3D model is built up layer by layer as the cured layer in the bed recedes down into the vet and new resin covers the previously cured layer. The resin covering the previous layer can now be cured by the ultraviolet laser to the previous layer, thus building the next layer of the part. Only the liquid polymers could be used in this process, and the product’s surface finish is better. b. In FDM, a thin filament

The ABET [6] recently updated the "student outcomes"related to hands-on labs and/or design projects, such as outcome (3): “communicate effectivelywith a range of audiences” and outcome (6): "develop and conduct appropriate experimentation,analyze and interpret data, and use engineering judgement to draw conclusions". Outcome (6)creates a new requirement for engineering educators, when compared with old outcomes (b) and(k), to assess students’ use of engineering judgement and their ability to conclude the outcomesof the labs and/or projects.This poses following research question for engineering educators looking to address the newaddition in ABET assessment: In the context of two junior-level engineering courses, how

The integration of these components yields varying levels of manufacturingtool cost, reliability and accuracy.2.1.1 Mechanical HardwareMulti-axis CNC motion can be generated using one of four methods: (1) moving gan-try/stationary bed Figure 2-1 (A & B); (2) moving gantry/moving bed Figure 2-1 (C & D); (3)stationary tool/moving bed Figure 2-2 (E & F); and (4) delta machine Figure 2-2 (G & H). Thecharacteristics and benefits of each are listed in Figure 2-1.The strategy differences in generating linear motion can be neglected in larger commercial CNCmachinery as they have been developed to compensate for loses. For example, a moving bed sys-tem

The intended use of the coupler is to connect two other metal parts.A 1018 mild steel with a diameter of 3” and a length of 10” is turned down to a diameter of 2.25”in three passes for a length of 7” on a manual engine lathe. Then, a 2” deep and 1.75” diameterhole is drilled on the uncut side of the
objects with wireless controllers.To study the problem-solving of engineering students, we invited them to complete someassembly tasks. Assembly tasks given to students involved the assembly of car toys according toa set of customer requirements as shown in Figure 3. Students needed to minimize the total costof car toy assembly while satisfying customer requirements. Hence, the assembly task consists offour main functions: design, sourcing, manufacturing, and inspection.Figure 2.

Trace around the motor and cut holes in the foam board for theservos. Make the holes for the servos a bit undersized so that the servos fit tight into the baseboard. You can experiment with different motor spacings and disk diameters to get the size/scaleof drawing you would like. If the motors are too close together, the scissor arms may reach toofar and the pen may run off the edge of the paper.

very good directional solidification back toward the gate and riser. Critical fractionsolid time results are shown. On the right is an optional mold layout and riser design analyzed bythe students.In the result shown in Figure 10, the initial result was good as far as solidification and would befine for a one-of-a-kind part made in lab. SolidCast™ has an easy feature to determine amount ofmetal going to part and riser. In the initial layout design, the part alone weighs 0.041 lbs. whilethe total for part, gate and riser is 0.161 lbs., which is a yield of 25%. This is relatively poormold efficiency. The version on the right has several changes: a) the riser has been changed fromcylindrical to rectangular, b) the overall riser volume is

commonformats are A-scan, B-scan and C-scan presentations. Each presentation provides differentinformation and interpretation for the evaluation of the inspected material. A-scan is a simplepresentation of ultrasonic signal as a function of time. The vertical axis represents the amount ofreceived ultrasonic energy and the horizontal axis displays the elapsed time. The size of thediscontinuity can be estimated by comparing the amplitude of the signal obtained from andunknown reflector to that from a known reflector. The depth of the reflector can be determined byobserving the signal position on the horizontal axis. B-scan is an image showing the cross-sectionalprofile of the test piece. In the B-scan the travel time of the sound energy is showed on the
