If you'd like more information or to see more of this project, watch this video: https://youtu.be/K3qXHZA-2Pk. This week's design is a World War II-era Welrod silenced pistol. I created this model for my dad because we used to play Medal of Honor Rising Sun together when I was younger. So I thought it would be a fun gift. I made this model in Fusion 360 by importing an image and tracing it with sketches. I then extruded the handle and most details, using the rotate tool to create the barrel. Next, I printed it out on my Robo 3D R1 using Hatchbox white PLA. Print settings are listed below. It took about 5 hours to print in three easy-to-print sections. Here's a step-by-step guide for post-processing: Step 1: Sand or file any rough spots. Step 2: Glue the three pieces together. No keys this time, but it's pretty clear which pieces attach to what and how they're oriented. Step 3: We applied some Contour Putty to help fill in the seams between parts. Spread it out evenly and sand it down if necessary. Step 4: We applied some XTC-3D epoxy to improve the surface finish and hide some print lines. Step 5: Apply plastic primer. Give it a few coats, letting it dry completely in between. Step 6: Apply Hammered Metal spray paint. Step 7: Apply black spray paint. Step 8: Scuff the finish strategically with sandpaper and a metal pick for scratching it. This gives a nice weathered effect. Leave the handle alone to give it a distinct appearance. Print settings: Layer Height: 0.3mm Infill: 20% Supports: Yes (under the trigger) Raft: No
