week 17. Wildcard Week

This Week i wanted to make something interesting with fabric and 3D- Printing. I lasercut a top, printed scales which are embedded onto mesh and combined everything at the end. What i did was some kind of Scale-Armor for Larp/Festivals.

The Process of infusing 3D-Prints with an additional Material like meshes was not coverd in any of the previous assignments.

3D-Printing

First thing i did was to 3d Print scales. I made two versions. The First version was the start, which has a row of different scales at the top added

404

The second is the same without the top row

Slicing with pause

I sliced the files for our BambuLab A1 with the Standard Settings in 0.2mm layer height and with the standard PLA settings.

404

After Slicing, i added a Pause. For this I slided the slider on the right side to the 2nd layer, rigth clicked and selected add Pause. After that, i rescliced the file again

404

Now you see after showing all Layers again the hint pause on the right side.

404

actual Printing

Actual Printing was straigth forward. I printed, till the second layer was finished and the printer stopped there

404

I then layed the mesh, in my case Insect Net, onto the Bed over the print and stretched it with magnets. I used 16 2x2 round neodym magnets.

404

After the print was done i removed it and thats the result.

404

Painting

To get to the right esthetics, I first primed the prints.

404

After 30min, I tested, which i colour i liked the best. I tryed Bronze and Silver. But went with Silver at the end.

404

2h after the Main color was applied, I applied a clearcoat and let it dry over night.

404

Fabricwork

For the Armor i made a simple "TankTop" Pattern, I lasercut later.

404

Ironing

Befor Lasercutting the Fabric, I needed to iron it first, to get it as even as possible.

404

Lasercutting (like in Week 3)

Testing the Cutting settings was the first part. I tested 3 Settings for Vector Cutting on our Epilog Fusion. First was 100% Speed and 50% Power(left Cut) which cut like a dashed line. With the 2nd test(center cut) i increased the Power to 75% which was significant better, but left some single strands uncut. The Final test cut(right) with Power set to 80 was the final setting, i used for the final cuts.

404

I stretched the Fabric onto a piece of MDF, which held the fabric in place and prevents moving while Cutting. I just taped the sides to the Wood.

404

I cut the Pattern two times

404

In the End i also cut two rectangles with the dimensions 550mmx90mm, which acts as filler pieces at the sides

Sewing

For sewing the parts together, i started by pining everything together.

404

I then started at the straps with a honeycombstitch with 4mm width and 2.2mm length. I used the stich to prevent fraying in the future

404
404

After the HoneyComb stich, i added a straigth stich with the same length as the actual stitch.

404

Every part was sawn togther

404

I also added a Border with a zigzag stitch

404

Combining everything

For Combining everything i glued edge scales of every panel and added some stitches by hand in between some scales of a panel. I also stitched the panels together that way. Of course, I needed to trim the mesh, so that the leftover overlapp with the leftovers another panel but not the scales of them.
