OK – so I thought I was done with the What’s New in Simplify3D Version 4 series …. seems not! When I made that series I skipped over one of the new features, “Improved Mesh Reduction”, simply stating I don’t use Simplify3D for mesh reduction. That was a bit of a cop out and I was asked to do a video of the feature. So here it is!
The previous video was supposed to cover both Starting and Ending G Code but it was getting a bit long, so I decided to cover the Ending G Code in a separate video – this is that video! In the first video I covered some G Code basics and where to set the starting and ending G Code in Slic3r, Simplify3D and Cura. So if you want those details see the previous video here.
I have come to the end of the new features in Simplify3D Version 4! The last feature I will be covering is called “External Fill Customization” and allows you to specify the angle at which top & bottom layers’ infill are printed.
This is useful if, for aesthetic purposes, you want all the external surfaces of your print to have a uniform or specific direction of filament, even when those surfaces are at differing heights. It could also be argued that you could increase the strength of a part by dictating the direction of the filament on the external layers. Simplify3D allowed you to set the internal infill layer directions in previous versions, so this new feature brings you the option to do that with the surface layers too.
Simplify3D Version 4 has brought some decent changes to the way it handles bridging. Some of these are changes that take effect with all bridges and some others come through as additional options you can set in the profile settings.
In the video above I go through the changes that have been made since Version 3 and see what effects they have, both in a theoretical preview and in real-world prints.
In this video I try out what Simplify3D refer to on their website as “Strong Foundations”. What this actually means is that in version 4 they have added a couple of new settings to improve the bed adhesion and overall strength of support material.
I look at what these new settings do and what that could mean for support structures – especially if you have ever had issues with the supports lifting off the printer bed.
In the fourth video showing the changes in Simplify3D I look at two new features that both rely on one main change – the ability for Simplify3D to attempt varying the extrusion width dynamically.
The first feature, “Variable Extrusion Sizing”, permits you to attempt to print features that might otherwise just not print at all, where the total feature size is very small. I demonstrate that this works to very good effect.
The second feature, “Dynamic Gap Fill”, comes in very handy where you have features that in the past left gaps between perimeters and infill, or between two perimeters on very small features. It fills in these gaps with filament which is extruded at a smaller width that your general settings allow.
The third video in my series on the changes in Version 4 of Simplify3D runs through the added functionality to use multiple processes on multiple parts when printing them one after the other, sequentially.
This feature will greatly assist those that sequentially print multiple parts that need their own individual split processes.
I also show the new feature in Version 4 which allows you to simply drag and drop the order in which the split processes are printed. If you got this wrong in previous versions it meant having to delete them all, starting again and creating them in a certain order. This too is a great time saver.
This features aims to remove any artifacts, or Z scars, from a print at the point of transition between two processes.
Before version 4 Simplify3D would insert solid layers between two different print settings in the same print, which could be visible in the resulting part.
I have a look at the theory and print out some tests in both version 3 and 4 to see what improvements are seen.
I had quite a fun time trying to get any differences to show up in photographs even though I used quite a high quality macro lens, nevertheless the photographs showing the difference between version 3 & 4 are below.
