Documentation

Welcome to ZeroG

Welcome

The Zero G documentation will give you a start building your project, learning all about 3D printing and more!

Getting Started

On this website you’ll find all sorts of information, , , , , and more!

Currently we’re working on instructions for two of our projects. Our projects are Mercury One.1 and Hydra.

The documentation is still a work in progress so keep in mind it’s not complete.

Discord

We’re a big advocate! We love using it and building a community. Missing something in the documentation, need assistance, share your adventure, or enjoy a nice community? Join our today!

Step Files!

The step files for Hydra and Mercury One.1 are now available.

Find them in the menu: Manual → OR → Files. There is a section called “Step files”.

License

We’re not using a GPL3 license like most other open source projects. Our work is licensed under a

What does this mean and why did you choose for this instead of GPL3?

What does this mean?

Why did you choose this license?

Printing tips

What material should I use?

ZeroG printers are designed to be printed using ABS or ASA. This means we’ve included tolerances for material shrinkage in our models.

It’s recommended to print your ABS or ASA parts inside of an enclosure, this will greatly increase layer strength.

We find that parts printed in ABS+ are weaker in layer adhesion compared to non ABS+ filaments. Although easier to print, they’re easier to break. We’re aware that not every blend of ABS+ is equal, however it’s what we found with the ABS+ we tested.

Calibration print

Check it out now! You can find it . This test print will assist you in determining the proper fitment of dowel pins, heatsets, and bolts, as well as testing the bridging and overhangs. The printable pages description will provide you with the necessary settings to use.

Analyzing a break

Great! Let's use this moment to check your layer adhesion. We mostly use our Steppers mounts or X Joints to check the adhesion. Below you’ll find a picture of a collection of breaks, on how it should look.

Example 1 - X Joint

Shows a break going across multiple layers. A break on multiple layers indicates good layer adhesion.

Example 2 - Stepper mount break

White stress marks showing on the break but nothing on multiple layers. White stress mark on plastic indicates force was needed to seperate the layers.

Example 3 - x joint

The part has been printed with a .6 nozzle showing a gap between the outer perimeter and the inner perimeters. It’s still a strong part, the break goes across multiple layers.

Filament choices

We've got a few materials that we do recommend, we've also listed some alternatives without a rating (1-5).

Bambulab
LDO ABS
3DO

White - You can, but we don’t recommend it. The pigment shows a ton of flaws and causes weak layer adhesion.

Print settings

We’ve designed our parts to work with the settings displayed below. Make sure to respect these settings, otherwise parts might turn out weak or look weird.

If you’re not happy with the print quality, join our Discord and ask for some help.

Recommended print settings

First layer height: 0.25mm (This is required. Our parts have been designed for this.)
Layer height: 0.2mm
Extrusion width: 0.4mm, forced
Infill percentage: 40%
Infill type: Adaptive Cubic, grid, gyroid, honeycomb, triangle, or cubic
Wall count: 4
Solid top/bottom layers: 5
Seam placement: REAR
- This is important as we have seam relieve features that line up with the seam placement.
Supports: NONE

Importing ZeroG files

Please be aware that the files you receive from us are already optimized for printing; we’ve exported everything as they should be printed. When importing them into your preferred slicer, they should display in the correct orientation. We advise against using the ‘auto rotate’ function in your slicer, as it can negatively impact seam placement and other print details. Improper rotation might also affect how materials shrink, leading to off-centered features and other discrepancies

Clearances you need when printing with ABS/ASA

Guidelines

This page includes the clearances you need when printing with ABS, they have been tested for shrinkage and turn out to be the best “general” settings for everyone to print without any clearance issues.

Quick note This page doesn't contain a 'single bill of materials'. Instead, it has links to sources we found or recommend. Each project will have its own bill of materials linked to sections on this page. This setup makes it easier for us to update. Found any broken URLs or links to the wrong content?

Frame

Blind joints, how do they work?

Learn how to assemble your frame using Blind Joints

The page will be updated with detailed information in the future. We have included the basic details for now to make sure we have some information on the website.

What is a Blind Joint?

A blind joint on an extrusion involves a through hole on the side of the extrusion. This hole will be used to tighten a bolt that will screw together with another piece of extrusion. This other piece most likely has a threaded hole on the end.

This setup secures two extrusions at a right angle without exposing any parts externally, providing a clean look and robust connection.
