Preparing models for 3D printing: Checklist

Here we are, we have a 3d printer and the models to print: what we have to do is prepare the models, here is a Checklist to follow! We have said it several times, the files must go through the slicing program.
If then, like me, you do not have a profile ready for each material, but vary materials so often that it would be useless to have a fixed profile, so go and change the slicer every time you may happen to forget something. A little forgetfulness can cost you a print! So how do you do it? 
To avoid forgetting when preparing the model for printing, I have built a very short checklist to follow.

It’s extremely trivial and schematic, after some use you will be automatically and then you have printed it on your head!

These are 5 simple adjustments, 5 fast controls to avoid returning and find a peace of mind in place of the model chosen! You just need to tick what you have checked, and just like a pilot before takeoff you will soon be ready to go. In some cases, the printer’s lit fans are reminiscent of the turbojet engines of commercial aircraft!


Let’s start:

  1. Checklist – ADJUST PERIMETERS: Set the number of perimeters according to the object, and how much resistance it should have. Same reasoning for the above and below, with a minimum setting of 6/8 layers.

    – Aesthetic only object: 0,8 mm (2 perimeters)
    – Object to be handled, e.g. clip, handgrip: 1,2 mm (3 perimeters)
    – Object subject to stress, e.g. nutcracker: 2 mm (5 perimeters)
  2. Checklist – TEMPERATURE: depends on the material you want to print, the temperatures are indicative, always follow the instructions of the manufacturers, the important thing is to remember to check them!

    – ABS –  Nozzle: 255° Plate: 90°+
    – PLA –  Nozzle: 200° Plate: OFF/max 60°
    – Nylon –  Nozzle: 255° Plate: 90+
    – ASA –  Nozzle: 255° Plate: 90+
    – PETG –  Nozzle: 240° Plate: 80° (for the first layer, then OFF).
  3. Checklist – INFILL: Exactly as for the perimeters, with one difference, if the print has a very large “roof” having a thicker infill can help to get a smoother surface and no holes.

    – Aesthetic only object: 10% infill
    – Object to be handled, e.g. clip, handgrip: 15%/25%
    – Object subject to stress, e.g. nutcracker: 35%/45% (45% only in extreme cases)
  4. Checklist – COOLING: to be modified according to the material 

    – ABS: OFF
    – PLA: 100%
    – Nylon: OFF
    – ASA: OFF
    – PETG: 25%/40%
  5. Checklist – SUPPORTS: only when really necessary. You can only set them attached to the dish and only from a certain degree up. It ‘s always good to turn them off if our figure does not need it because they may turn on in unsuitable places and ruin the press. How could they serve and not be active!

This simple test will allow you to continue to use a single profile for the slicer and only check the settings that really make a difference and are to be changed according to the model and material used!

Act as a community member!

You can also copy this checklist on a word file, and print it. So everytime you starting a print you can check every step. 
If you think this checklist miss something please add your comment, so all reader can profit of your idea!
