3D print for patterns

Recommended Posts

Just wondered if anyone had considered making patterns using 3D printers instead of acrilic patterns

My thinking is that they could be made as a base with a thin raised edge for the actual pattern and being used to press onto a damp leather to leave the design with a cutting line just like craftaid, this would enable more detailed patterns and save the tracing errors that may occure with acrilic patterns

The problem is time, expense and refinement.  Most printers leave subtle lines on the surface of the finished item and those would transfer to the leather.  Acrylic is cheaper.

What @immiketoo said is true but on the other hand many tools and machines I use every day I have been told would or could not work. That is what I love to hear caus it often means if I can make it work I am one step ahead of the rest, until I share it here of course.

That is the question of course. I would start by making the lines higher than normal and allow that the lines may need to be smoothed out. You can smooth pla with a warm iron and it can be painted to smooth as well. Also consider the raised shapes possible that can be done in the moulding as well from the back side. Do you have a 3D printer yet?

Hi

Thanks, no printer at present but considering getting a basic one to learn, but trying to think of practical things to make and possibly sell

That thought never entered my head, I just decided I wanted one and felt that it was about time I learned something about them.  I actually had no idea whether it would be useful when I bought it. :lol:

The possibilities are endless. I make ring boxes from pla which I cover in leather and printed the tools to help me assemble them as well. There is room for a lot of different shape boxes and such, bangles to cover, pouch covers to mould and endless tool improvements.Just need imagination........ My latest tool improvement is to give one of my edging machines a way of adjusting the edging thickness in a more incremental way.

1st pic shows how the thickness adjustment was done previously.This is done by pulling in and out from the knurled roller by hand. Note that the silly brush wiper it came with is now an aluminium piece now. That was an earlier improvement.

This second pic shows what I printed to allow me to adjust the thickness now by even a mm fraction.

After drawing the parts(about 20 minutes after some measurements) I decided to print it in 2 parts but so that it could all be done at the same time.

A bit of super glue ...it works great on pla.

I can only say that I wish I had one of these 20 years ago as the amount of molds and jigs and so on would have saved me a fortune in time. Where I once spent hours making moulds out of wood on my bandsaw and sander for say my lipstick cases I can now print as many as I want whenever I need more and still keep working. That is the same now for many of my products as shown in a couple below

This week if time allows a local MC club want a stack of belts with 1" letters stamped in a long string of words so.... A block will need to be printed to saddle a 1+1/2" belt with spacings for the letter set and I will bet a few here would like something like that. I repeat..." The possibilities are endless"
