The students must possess basic knowledge of modeling and creating lineups of the individual parts. We created the model in Autodesk Inventor software. It is necessary to know and understand the sketch environment, including the knowledge of dimensioning, bonds, etc. Further on, functions such as ejection, rotation, spiral, field, and more. When dealing with lineups, bonds, restrictions of bonds, animation of bonds, and collision controls are used. Further on, it is necessary to be able to export the model as an STL and to be able to prepare the program for the 3D printer in Prusaslicer software and be able to use and control the printer. Lastly, it is necessary to use a screwdriver to assemble the individual parts.
The goal objective of this project was to design, 3D print, and assemble a workbench vice. The students had to construct a vice of a suitable size and dimensions for a mini-workshop mentioned above. The main objective was to deepen the knowledge and skills acquired in previous lessons. The students had to create 3D models of individual parts with emphasis on simple 3D printing, preferably without the necessity for support. Then it was necessary to assemble a virtual lineup from the individual parts, verify their assemble ability, check for possible collisions between individual parts, etc. The next objective was to introduce the Prusaslicer software to the students in detail and to teach them how to prepare G-code for 3D printers and, of course, the 3D printing process itself. The students then verified their performance by printing and assembling the lineup.
-usual IT classroom equipment -common workshop tools – PZ screwdriver, cutter knife, event. sandpaper -3D printer – engineering tables - fasteners: - screw 3,5x30 6 pcs(jaws) - screw 3,5x701 pcs (beam + threaded rod) - screw 3,5x50 6 pcs (nut + vice body) - screws 3,5x60 7 pcs (movable jaw + thread case) It would be better to optimize individual parts so screws of the same length can be used for assembling all parts. A problem could occur when assembling the jaws with the body of the vice as there is not enough room for longer screws.
Before starting the project, you need to get the necessary material, in this case it is only screws to connect the individual parts. Work on the modeling itself can last between 6-8 teaching hours, depending on the skill of the students and their ability to work independently in the modeling software. After printing, there is no need to adjust the individual parts in any way, just remove possible stringing and minor imperfections. Assembly should be done in 1 hour. The total printing time of one vise is therefore approximately 110 hours.
