Jonas – Ideamaker notes:

I used the Linux version on Arch Linux.  There is no Arch Linux version, just an Ubuntu 32 or 64 bit version. Use the AUR (Arch User Repository) program debtap to repack the .deb download file into an Arch Linux installable package. Debtap use article here:

  1. I tried Ideamaker in an effort to repair an OnShape model that was missing parts after importing into Slic3r. The auto fix didn’t work for me. It actually closed an opening on the model that I did want to keep. I was able to add custom supports to my model which was the one feature I could use.
  2. I’ve used Crua, Slic3r and KISSlicer. I did not like the workflow of Ideamaker at all. I didn’t find a pleasant way to save profiles for prints. I’m used to easily saving any changes with a new profile label in Slic3r one of three different areas of print settings (print speed/infill;  temp and extruder width; and hotend/gcode settings). From what I can find, Ideamaker forces you to first start printing, then a window opens to choose a profile. If you don’t already have a profile created(There were no preset profiles in the Linux version I tried), you must clone/duplicate a non-existent profile. If it’s your first time in this window there are no items to duplicate which was confusing. Unintuitively, if you do click the duplicate button (of which there is no selection to duplicate) that’s when a new blank profile option window appears to edit. Unless there is a Advanced/Expert preference button somewhere, the options for the profiles feel less complete than even the basic Cura.
  3. I also could not connect Ideamaker to my octoprint. Definite deal killer! Clicking the button to connect wirelessly to a printer seems to look for one of the approved Ideamaker supported printers. I did not try to connect my machine to the printer directly since I never use my printer that way. I expect that there would be some generic serial connection that would detect the basic gcode type printers everyone has.
  4. I installed Ideamker because it offered the extra features of custom supports which does seem to work a lot like the paid Simplify 3D. It also offers model repairing supposedly like the free meshmaker. Since that didn’t work for me the only feature left I like is the custom support creation. Given the choice of this or Simplify 3D for the features, I would easily choose Simplify 3D. I wouldn’t mind learning a new workflow for better features, but the usability needs more work for me to switch. For now the only use for me is to add custom supports without having to pay for Simplify 3D.

Rocket Battery Charger – or, 3D printing product development from start to finish:

Again, this is the first time I’m doing this, which, on the internet, means I’m an expert, Yay!

Product: USB charge bank in the shape of a rocket.

I’m just about finished with my rocket battery charger project. The idea is to package a USB 5V charger in an interesting case. I saw a battery charger put together in a plain square printed box, but I wanted something a little more interesting.


Business Process:

  1. Feasibility:
    1. Has anyone made something similar?
    2. Can you get parts?
    3. How useful is the product
    4. Do you have any real numbers on the market for the product?
    5. Can you make the product more interesting, better, cheaper at the same or better quality? I have more than one battery pack charger that I use regularly and could always use another one. For myself, my product is feasible because I already own two and could always use another. And, I can make it more interesting than the ones I already own. I expect other people may feel the same.
  2. Design:
    1. Consider creating your own design or modifying an existing model.
    2. Consider printing all one piece or multiple pieces.
    3. How will the part or parts print on the bed. My first idea was to print all in one piece. Printing a rocket vertically means the fins of my rocket would have printed first which means the thin points of the fins, very thin and weak, could not support the print until the body of the rocket printerd. I found it was difficult to get a good print without a lot of supports that would have affected the look. I soon switched to breaking the model into parts. It’s much easier to print the body and then attach the fins later. Side benefit is you can print different color or different materials for an interesting mix and match model.
    4. Think about over hangs when printing. To print without supports, you’ll want to angle your overhangs less than 45 degrees unless you’re willing to print with supports.
    5. Makers Muse talks about tolerance a lot. When you’re 3D printing, you need to leave .2 or .3mm of space between parts that you want to be snug fit. If you’re printing something the accuracy of the print is going to vary a bit. If your printer is perfectly tuned, most cannot really print to .1mm tolerance. .2mm tolerance is for a perfect printer printing slowly. .3 is probably more realistic for printing fast.
  3. Materials: What kind of filament will work for the product?
    1. Does it need to be strong?
    2. Does it need to withstand heat?
    3. Is the product going to be knocked around, or just for display?
    4. Should the model be a certain color
    5. How big does it need to be?
  4. Production: If all things are available and the design is ready
    1. 3D printing things 1) How long does it take to print the parts? 2) Can you print enough before your deadline? 3) For multipart, are your tolerances going to work for real world application.
    2. How long will it take to make one complete product that is ready to sell.
    3. Can you make the product more quickly?
    4. Are there any steps that can be outsourced, like basic assembly or fulfillment?
