On Thingiverse I’ve found this cute hand. I thought it might be fun to scale this to “life size” and then print it, without infill, except in the fingertips, to get a real smooth top.
The bottom was not completely flat to drop on the printbed. So I would need supports and/or raft. I wanted to print without those and have created a base plate in Slic3r PE, to create good bed adhesion and get better stabilty after printing for the finished model.
So for starters:
- scaled the model to “life size” (185 mm tall)
- layer: 0.15 (1st layer: 0.2)
- infill: 0%
- bottom layers: 4
- top layers: 6
- perimeters: 3
- nozzle temp: 203° C (1st layer 210°C)
- bed temp: 55°C (1st layer: 60°C)
- speed 50 mm/s
- filament: Kaisertech PLA White (review here)
The end result needed to become something like this:
The fingertips I wanted smooth. The bottom needed to be flat for adhesion and stability.
How to achieve this? By using “blocks”, also called “generic part” or “generic modifier”.
In Slic3r PE, you double click the item you want to adjust. (In this case, there’s only 1 item on the printbed: the hand).
A new window pops open:
When clicking “load generic”, you can insert a new item. This is called”lambda”.
Then you can add the dimensions you want (in millimeter).
In my case, I have created 6 blocks.
The first item is the original stl, then 5 green boxes containing each a fingertip. The last one is the base plate (yellow).
On the bottom, you can slide each item untill it has reached the desired position. If necessary, you can manual input a value too.
The base plate is an “object” (part), I’ve added infill options to it. You can do this by clicking on the green +-sign and chose the option you desire. This way, you overrule the standard settings from the slicer.
The other 5 blocks, I positioned in such a way that they contain the fingertips completely.
These are “modifiers”. They adjust the chosen object on the inside of the lambda-box. Everthying from the lambda-box that falls OUT of the model, is NOT being printed.
The result gives me:
In other slicers, you need to adjust complete layers. In this case, you only change the settings for a “block”. You can put more then 1 block on the same height, each with their own, different settings.
This way, you reduce printtime, use less filamnet and it should result in better print quality mooier resultaat.
