    Real World 3D Printer Comparison

    Well this idea started out in another thread and I want to thank Roberts_Clif for this idea. So basically I made a comment about 32 bit boards being better and this person challenged me with printing something out in a given time. He posted up a .stl file and some settings and then I tried to print the same with my printer. In this forum where there are so many threads asking which is better and everybody posting up there ideas and opinions here is a chance to generate some real world results and comparisons. So Roberts_Clif can print this part in 1hr 38 min on his 8 bit board. After my comment based on the given understanding about the 32 bit boards and their advantages when I tried I was able to print at 1hr and 51min. From here I have gone further and re printed the same part raising the print speed to 120 and then 130% and I got close to this person's time.. Just a minute over his time but there are imperfections starting to show.. This challenge has revealed truth beyond ideas and opinions. Namely that Roberts_Clif was right and an 8 bit board can drive a printer at good speeds. It let me know that at higher print speeds I need to up my extrusion multiplier or e steps. And it is also a great way for us to compare our different printers. Is a Creality better than a Hictop or a TronXY? Well let's answer some of those questions. Post up a stl file and how long it took you to print it with what specs and on what printer and lets see who can generate the better results. And show us some high quality pictures of how the print came out. Not as a race to a finish line but to identify issues and dig our ways through tuning our stuff to as close to perfection as we can get them on our way to finding out who is really making the better product.

    This is a good thread, wish I would have thought of it.

    I have two 3D Printers "Red is a 12V Hictop 3DP11 " "Blu is a 24V Hictop 3DP12" the Printing is quite similar on Both 3D Printers.
    My 12V 3D Printer can print ABS however it takes longer to get up to temperatures for printing ABS.

    And my 3D Prints are not perfect although I have the benefit of having a 20-20 T-Slot Frame, this is a strong construction.

    On some models where there are mounting holes I get distortion, I just read an article of how to correct this artifacting.
    Now I will have to reprint this model to see how well it clears the actual artifacting.
    I do not know the time required to print this model with the additional settings enabled.

    I do know that the time changes considerable with different slicers and have been playing with Prusaslicer 2.3.0 alpha it has best prints though it also take the longest.

    I have sliced the same models with the following slicers
    Cura 15.04.6 1 hour 21 minutes
    Creality Slicer 1.2.3 1 hour 20 minutes
    Cura 3.6.0 1 hour 32 minutes
    Cura 4.7.0 1 hour 37 minutes
    Prusa 2.3.0 alpha 4 1 hours 57 minutes // Need help getting the Print speed decreased on this slicer please

    All in all not to bad for estimated print speeds of course the actual print is a little longer.

    So lets have some fun. Go get this: Lattice Cube 3D Printer Torture Test (Overhangs and Dual-Extrusion) by Lazerlord - Thingiverse just the first file on the list is what we should do. Just the basic lattice cube. Print it out as best you can for a base time on a good quality print. I will do the same. Then we can compare settings, time, and print quality. And start chasing each others better specs.

    Here is a 1st Print - Have never tried this before and will print again as Cura 3.6.0 did this model no justice.

    Layer .24
    Print speed variable throughout the Model
    No Supports
    Photo taken at 2 hours 39 minutes]
    Final Time was 2 hours 52 minutes.

    Almost embarrassed to show this Print
    Will change slicer an make changes to the slicer profile post again.
