New Minimal 3DP Website

New Website

With my previous website, I put it together with Wordpress. As what typically happens, WordPress was just too cumbersome for me to maintain. Additionally, it seemed like someone was always trying to hack it. It was a pain and I worried about the hacks.

I have used Hugo in the past and I thought I would try to rewrite the site in it. I liked the Docsy theme but I was not sure I could create the Klipper Calibration website. It turns out it was easier that I thought.

Klipper Calibration

One of my main goals for creating this site, is the Klipper Calibration calculators I have put together. I have my Klipper Calibration Spreadsheet but many people are requesting edit access. To simplify things, I thought it would be a good idea to create these online tools. It also gave me the opportunity to do some simple programming. It has been a while.

Because I am using Docsy, there are tools built in to leave comments and post issues on github. I thought this integration would be helpful as I tried to improve and expand the tools. I am looking forward to the feedback. I know that there is room for improvement.

Projects

To many time I do not document my work well enough. I have several different tools for reference and documentation. Because it is several different tools, I never know where to look. With this in mind, I am hoping this site can serve as a repository of knowledge for my work. I sometime wish I had more time. There are so many cool ideas to try. Hopefully, I will have a chance to explore.

Blog

The blog is a minor feature for me. I always have good intentions for keeping it up but I always have trouble finding the time. We will see how this iteration goes. I am thinking that Hugo will make it easy. A lot of content here was done via my iPhone. Working Copy and Textastic are amazing apps and worth every penny.

3D Printing and Max Volumetric Speed

Finding Your 3D Printer’s Sweet Spot - A Guide to Maximizing Print Speed

Have you ever wondered how fast your 3D printer can truly go? When I get a new printer or see a new model released, the first question that pops into my head is always, “How fast can I print with this thing?”

This post will explore how to determine the optimal print speed for your 3D printer, ensuring both speed and quality.

Factors Influencing Print Speed

Print Parameters

• Infill: While not a major time-saver, adjusting infill patterns and density can slightly reduce print time.
• Wall Thickness: Reducing the number of walls can significantly decrease print time, but it can also compromise the model’s strength.
• Layer Height: Increasing layer height generally speeds up printing, but it can also affect print quality and part strength.
• Other Parameters: Factors like print speed, infill density, and layer height also impact the mechanical properties of the printed part, according to research. Finding the balance between speed and strength is crucial.

Extruder Limitations

• Max Flow Rate: Each extruder has a maximum flow rate, which determines how much filament it can push out per second. Exceeding this limit leads to inconsistent extrusion, poor print quality, and weaker parts.

Determining Max Flow Rate

Ellis’s Print Tuning Guide provides valuable information and equations to calculate your extruder’s max flow rate. A simple test involves extruding a known length of filament at increasing speeds until you observe a noticeable drop in extrusion quality.

One of the key points that Ellis’ guide points out is that using approximate values (Table 1) is possible.

Finding the Sweet Spot

Determine Max Flow Rate: Conduct tests as described above to find your extruder’s maximum volumetric flow rate. Set Volumetric Speed: Adjust the volumetric speed setting in your slicer software to match your calculated max flow rate. Optimize Print Profiles: Experiment with different print speed settings for various parts of the model, ensuring that the speeds for visible features do not exceed the calculated safe limit. Test and Iterate: Print test parts and adjust parameters based on the results. Observe print quality, part strength, and overall print time.

Important Considerations

• Model Size: Smaller models may not allow the printer to reach maximum speed due to acceleration and deceleration times.

• Part Complexity: Complex models with intricate details may require slower print speeds to ensure accurate and high-quality results.

By carefully considering these factors and conducting thorough testing, you can optimize your 3D printer’s print speed while maintaining excellent print quality and part strength.

Disclaimer: This information is for general guidance only. Always refer to your printer’s manual and manufacturer’s recommendations for specific instructions and safety guidelines.

I hope this guide helps you unlock your 3D printer’s full potential!

This Week on Minimal 3DP (April 28)

The Week of April 28st 2024

I am currently working on several projects this week. They include:

• Voron 2.4 R2 Pro+ Build
• Orca Slicer Seam Settings
• STEM Outreach

Voron 2.4 R2 Pro+ Build

i recordedcan unboxing video on Sunday and I have begun building the Voron this week. I am working myvway through the assembly manual and wiol drop a vireo of rrame assembly next weekend.

Orca Slicer Tutorials

I am working to add to my Orca Slicer tutorials th ok s week. i want to do a post on ideal settings for support (based on a viewer question) and do a video on my recommendation for seam settings.

STEM Outreach

As part of my job, I sometimes do STEM outreach with local schools. This usually involves taking a 3D printer and talking to kids (and parents) about STEM careers. Before I go to an event, I have gotten into the habit of 3D printing a bunch of print-in-place and flexi animals to give out. This week I am hoping to print 100 animals.

The Week of April 21st 2024

I am currently working on several projects this week. They include:

• Voron 2.4 R2 Pro+ Build
• Belt Driven Ender 3
• STEM Outreach

Voron 2.4 R2 Pro+ Build

I have started getting together my project website for my Voron build. One of the newer ideas I am trying is to create a project website. I am hoping that it makes it easier for me to save references and other links. I typically try to research a project before I begin and it will make it to asier to share my research.

With the Voron build, I have mostly saved basic references from the Voron site. I have also saved doc from the FormBot site. They appear to have some updated instructions for their kits.

Belt Driven Ender 3

I stumbled across this project a while ago. It seemed like an interesting conversion for my Ender 3 v2. This week I am going to work on adding a project website and printing the needed parts. The hardware cost less than $30 USD.

Klipper Calibration Website

Klipper Calibration

A while ago, I create the my Klipper Calibration Spreadsheet to help myself keep track of and remember various Klipper formulas to tune and improve my 3D prints. I decided to share the tools and i have received lots of requests to share the Spreadsheet. Rather than giving everyone access to edit my original sheet, I have recommended to everyone to “Make a Copy” of the sheet for their personal use. In a lot of cases this has caused some confusion. By making a copy, there is no way to any edits or updates I do to the tools.

Because of this (and my desire to do a little programming), I have put together the Klipper Calibration Website. The standalone site gives me an opportunity to create some useful tools and program. It also give me a way to create more detailed documentation and video links.

Another hope is that, because I am using Docsy, I can use the tie-ins with GitHub to allow the community to comment, make suggestions, and give feedback. I could than further refine the tools. It is my hope that this site will continue to evolve over time and include additional tools.
