3D printed shaving stuff

From a first look I've had, resin is around £32 with free delivery here for the GEM type.

Standard printing is around 7-8gr. total for this piece, right?
But how about resin? Does the weight go upwards considerably, e.g. 20-25gr. or even more, perhaps?

I was debating whether to post this kind of info here or not, but I hope it will help anyone who is not very familiar with 3d printing and is either going to print or is having items printed. While every 3d printer is unique in the form of its hardware and software, some settings (layer height) are fairly universal. Most of my razors are designed with a 0.1 and/or 0.12 layer increment rule in mind. Leaving all technical jargon aside, I've attached two sliced illustrations of the Min-GEM-Razor head for comparison. You can clearly see how much detail is lost when it's printed at 0.2mm layer height vs 0.1mm layer height. At 0.1mm you can see that a very small radius generated six layers on the slicer, whereas the 0.2mm layer only generated one or two, and the small radius isn't well defined. You think you would get at least three layers since 0.2mm is half the resolution of 0.1mm. If it all seems confusing, you can simply stick to the rule that if the part fits in your hand, you should print it at the highest resolution possible. Recommended settings for the Min-GEM-Razor printed on FDM printers are 0.12mm layer height, 3.5 shells, 100% infill, and no raft and/or supports. If printing with SLA printers, you can set the angle on the razor's head 20 to 30 degrees from its original position, and 5 degrees for the handle with supports generated accordingly.

Please do keep posting this kind of stuff.
Not having a 3D printer I have been mostly ignoring the entire slicing malarkey.
Maybe I should get some slicing software for better communication with the print guy.
Anything you can recommend? (Linux or macOS only I'm afraid)

Resins and PLA have almost the same density, with ABS being slightly lighter. Most 3D-printing filaments have similar densities, so controlling the weight by choice of material is limited.
There are some PLA/metal mix materials that have a higher density (double, maybe three times), but you have to find a printer that stocks them.

All the popular slicers work with macOS and Linux. I've only used Cura and Ideamaker on Mint Ulyana and have had a better workflow with Ideamaker. Ideamaker has been my preferred slicer since it's early development. And of course, except for Siplify3D, all the popular slicers are free.

Thanks,
I can see why this kind of software would be available for Linux.
I reckon the percentage of Linux users among 3D printing folk is higher than average.
I have installed slic3r, Cura and Ideamaker and now need to find out what they do :)

Awesome! Your feedback will be much appreciated.
My order has arrived from the printer and I don't have the head magnets for the Slantibartfast with me. Bad planning.
(The magnet hinge works a treat though. :woot:)
So without further ado, I decided to have a shave with your razor.
First of all - the looks:
Love it. The blade sticking out of the back of the head reminds me of the frills of a triceratops.
If I had to name the razor... Well, I don't.
Even the ultra-cheap print I got looks good.
The way the blade is fixed in the head is really neat. Elegant and effective. You slide the blade into the back of the head, similar to an Enders Speed, then give the handle a few turns to fix the blade in place. Nice and simple.
Best of all:
I had a great shave.
The angle goes as shallow or steep as you like. There is good audile feedback and the razor was easily moved around my face. It is manoeuvrable and I could get to difficult areas with ease.
The razor is a bit more aggressive than a 1912 or a Micromatic, but not so much as to worry me.
I ended up with a full-on BBS shave without injury or irritation.

To sum up: You're on to a winner here. If this razor was available in old-fashioned metal, I'd probably buy one.
As it stands I urge everyone to have one printed. It's one cool razor.

Verdict: 👍👍👍👍👍

Well! I think it's safe to say that your feedback puts the finishing touches on this design. I will modify it no more. :)

The original file name for this design was "Minimalist_GEM_SE", but I'm liking the sound Triceratops. Hmmm... Will have to let that float for a while and see where it lands. :)

I'm going to add an SLA file on Thingiverse that includes the razor head and handle at their optimal angles, and with built-in supports. Thanks for the feedback. I'm glad it worked out for you.

I've added another file on Thingiverse for SLA printing. File "Min_GEM_SLA_with_supports.stl" includes razor head and handle at their optimal angles, and with built-in supports.

Here's a printing tip: Printing time on SLA printers is based on the number of layers, not the number of objects on the build plate. If you are using a printing service that charges printing time plus material, you are better off printing multiple parts in one run, assuming they're all the same color. Printing one razor takes just as long as printing twelve in the same run. The only difference is a bit more material.

Please educate me.
What's the advantage of printing it as the leaning handle of Pisa?
What makes the angle optimal?

Did you request layer thickness from the print company?

In SLA printing, the parts are printed upside down and lifted off the resin vat over the exposure screen layer by layer, so the supports are actually hangers. By angling the handle, it minimizes the surface tension on the first few layers (bottom of handle) connected to supports as it is being lifted off the screen. The optimal angle is part dependant, and it's the angle that has the least surface tension and the least required supports combined.
