Slicer Compare

This repository contains a small comparison of slicer software. All tests were done with an Anet A8 without modifications beside new electronics (RAMPS 1.4 board). This is not a full blown test of each software, but a quick test of the different slicers including a small test print.

Software

The following slicers were tested:

Test Content

I printed a Benchy scaled to 63%. I did the scaling to speed up the print time and to intense the challenge for my printer and the slicer software. Furthermore I tested the performance of the slicers in the following categories (three times each):

Opening a STL
Slicing
Saving the G-Code

I added some comments to each slicer in none particular order or relevance. Just things which I think are worth mentioning.

Profile Settings

General Settings

Layer Height: 0.2mm
Nozzle Diameter: 0.4mm
Wall Thickness: 1.2mm
Top / Bottom Layers: 3
Infill Density: 20%
Material: FilamentPM PETG 220°C - Heatbed 75°C
Fan Speed: 80% - Switched off for the first three layers
Skirt: 3 Lines

Speed Settings

Default Speed: 60mm/s
Travel Speed: 100mm/s
First Layer Speed: 25%
Perimeters / Top / Bottom Speed: 50%
Infill Speed: 125%
Retraction Length/Speed: 3mm - 60mm/s

Everything else remained at default. Differences in print time are possible due to automatic slow downs by some of the slicers.

Results

Cura 3.1

Cura

Times

The time to open a STL and the first slice time are measured together, because Cura makes the first slice instantly after adding a STL.

Open + Slice: 11.01s / 10.67s / 10.67s
Save: Instant

Good choice for beginners. Doesn’t expose to many settings in the beginning, but an experienced user is able to add/view advanced settings/properties. All settings are saved into a single profile. Cura does not differentiate between settings for materials or other types of properties. Relatively fast performance and easy to use UI. Time estimates can be way off, if you don’t use a Ultimaker.

ideaMaker 2.6

Model viewer was a bit laggy. Manual support structures possible. All settings are saved into a single profile. ideaMaker does not differentiate between settings for materials or other types of properties, but the profile management is solved quite good.

Great for beginners. Every setting is explained with a description and a small animation. Manual support structures possible. Easy to use UI and great slice preview.

IceSL 2.1.10

icesl

Times

The time for slice and save are measured together, because IceSL saves the GCode directly after slicing. The slicing time depends on your created profile scripts.

Open: Instant
Slice+Save: 1.68s / 1.62s / 1.61s

Not for beginners or even experienced users without programming knowledge. The UI is very simple, but many of the settings are done in LUA scripting files which is not something every user wants to do. If you know how, IceSL has a very nice profile management. I think it is one of the best. IceSL comes with a feature called adaptive layering. For example it is easily possible to print a model with different layer heights or speed.

If you know how to use it, IceSL is really great!

KISSlicer 1.6.2

KISSlicer just exposes the most common and important settings and uses default values for the remaining. UI and performance was not the best in this matchup.

Many options could confuse beginners, but are great for experienced users. Users are able to create profiles for materials, printers and print settings.

Many options could confuse beginners, but are great for experienced users. Users are able to create profiles for materials, printers and print settings. Provides a feature similar to IceSLs ‘adaptive layering’. Better performance than the “original” Slic3r.

Very good performance. Manual supports possible, nice handlig of different settings for different models or layers in you print - called processes. Only non-free slicer on this list. I think it is a bit pricey. The other slicers are also able to produce very good results and they are free!
