Another way to print frames using the TKS Frame as an example.
Back in the summer of 2021 I tested diffrent ways of printing micro frames.
The goal was to print a micro frame that was as strong and stable as possible with ordinary filaments. In my opinion nylon, carbonx filaments and stuff like that have the problem that they are expensive and/or difficult to print. So I thought about whether I could combine the filament properties of PLA, PETG with TPU or Soft PLA. And it works.

how is it done?

1. Choose a 3d print frame
2. Choose the filaments combination you want
   • Filament: What is working? My test have shown that following combinations works fine : Petg or asa on tpu or SOFTPLA on PLA or Pla on Softpla. Sandwich prints are difficult. Most of the time there is no good adhesion of TPU on PETG. But the adhesion of PETG on TPU is very good. only softpla-pla-softpla works as a "sandwich" print in my tests.
3. In the slicer program, choose a layer for color changes in which you change the filament.
   • You can decide for example how much TPU should be printed in relation to PETG.
   • How many layers you print in one filament also depends on your print resolution. Therefore, no precise statement is possible here. In the PETG-TPU example, I like a ratio of around 5-15% TPU.

4. The key is before the filament change takes place : rise the nozzle and bed temperatures abnormally high.
   example: PETG (Prusa) on TPU(Sainsmart):
   start with TPU
   65 degree bed
   220 degree nozzle
   2 Layers before filament change:
   Increase bed temperature to 100
   increase nozzle temperature to 220-240
   After tpu is printed:
   quick switch to PETG
   start printing PETG around 250-260 degrees (first layers hot as possible)
   Bed temperature still at 100 and leave it there
   print slowly with 10-30 mm / s

   I think MIXED PRINTS are a cool thing to try and experiment.

I created a video in German. The subtitles were lost. I will add the subtitles next days.
