Welcome to Documentation

This is the big idea.

We communicate directly with hospitals that are most effected by the pandemic. They let us know a ball park figure of how many units are needed.

We then take that information and display it on the home page of relevium.tech.

Donar’s can view which hospital are currently prioritized and can donate funding to the hospital needs by purchasing a job order.

Funds are allocated to the 3D printing production line.

The 3D Printing Nation Wide Production Line:

Every 3D printing vendor has a unique production capacity. For e.g. It could be a friend of mine that has one or two 3D printing units or it can be a 3D printing professional that has 15 gnarly 3d printers that can hack out 100’s of units a week.

To solve this problem. We have integrated a special feature that allows the 3D printer to control its own production capacity.

Simply put. The 3D printer can input a “Stock Quantity” and when donors have purchased the “stock quantity” limit, the 3D printer will then automatically be taken off the production line since he has reached his production capacity. 

We hope that this system ill produce and allocate the resources needed to hospitals in the most efficient way.

The 3D printed Halo pieces and the plastic sheets are sent to relevium HQ for QA evaluation. They are then paired and put into a box to be shipped to the Hospital!

The Hospital Demand Line:

Since hundreds of 3d printers will be at work simultaneously to fill a demand for a hospital and once the donors have purchased enough jobs for the 3d printers to fulfill that hospital need, the 3d printers jobs for that hospital need will be taken off the site for purchase.

The next Hospital in line , Hospital B will be issued the resources next and will be fulfilled by the available 3D printers that are currently not at capacity. This goes on until this is hopefully over some time soon.

Printing Guide - Protective Visor

Brought to you by the kind folks at: 3DVERKSTAN

This is the guide on how to choose your print settings and print the protective visors / face shields. For best quality we strongly recommend that you follow these settings. The settings described below is described with the terminology used in Ultimaker Cura, but they should be possible to enter in any slicer on the market that allows you to change settings.

Quality Checking

Make sure that: - layers adhere properly to each other - walls are completely fused together - surfaces are smooth without gaps - the print has decent flexibility The settings described below is described with the terminology used in Ultimaker Cura, but they should be possible to enter in any slicer on the market that allows you to change settings.



This model is made to print with no infill at all. But it is also made to be printed fully solid. This means that you can set your infill percentage to 0%, as long as you follow the suggested line width and wall number settings below. This will make your print the strongest and fastest to print.

It is important that the print has as few voids as possible, since this will increase the drying time every time it is dipped in disenfectant solution and make it harder to clean.


Since one of the key things in this project is to get the production volume high, if you have the possibility, we suggest you to use a larger than standard nozzle and a larger layer height than you may be used to.

The parts are fully printable with nozzles up to 1.2mm if you choose proper settings, and if you have a high-flow hotend like the Mosquito Magnum or the E3D Supervolcano you should try to use these to your advantage.

What you have to do is to set all your line widths to a multiple of approximately 4mm.

Be aware that Cura hides quite a few of the settings as deafult, so turn the setting visibility to "expert"

Set your number of walls to be equal to ~2.5mm, so with 0.8mm line width you should have at least 3 walls thickness, with 0.4mm it should be at least 5, and with 1.33mm line width only 2 walls is needed.

This means that the optimal line width is:


Since this design has no real overhangs and little need for cooling, the main limiting factor for how fast you can push out these frames will be your hotend flow rate.

The hotend flow rate is the number that determines how much plastic your printer can melt in a certain amount of time.

If you just want to start printing:

Start with our suggested layer thickness and line width for the nozzle you are using, and a print speed of at 40mm/sec. This should work on almost any printer.

Make sure to set all the different print speed settings to the same number, this design caters very well to this.

Ultimaker Cura has quite a few "hidden" print speed settings, but if you turn on "expert" mode you can set all of them.

The only one that should be lower is the "initial layer print speed", since it important for bed adhesion. A good starting value is about 20mm/sec.

If you are a advanced user and want to speed up production:

For a regular E3D V6 this is about 10mm3/sec, wich with a 0.8mm nozzle and 0.3mm layer height is calculated as: 10mm^3/(0.8mm*0.3mm) = ~40mm/sec,

A high-flow hotend like the Mosquito magnum with a 0.8mm nozzle and a 1.0mm line width can on the other hand push more than 30mm3/sec, or 30mm^3/(1.0mm*0.5mm)= ~60mm/sec

A super high flow hotend like the E3D Supervolcano can melt up to 100mm3/sec, and with a 1.2mm nozzle and 1.33mm line width it can push 100mm3^3/(1.33mm*0.6mm) = ~125mm/sec

In practice, it might be hard to reach these numbers for other reasons, and if you see signs of your printer underextruding or wanting to grind, start by lowering your print speed by 5mm/sec and increasing your print temperature by 5 degrees.
