Put your 3d printer or CNC on this open source map

Matteo developed this digital fabrication tools open source map. You can put your rent / share   machine of any kind on the map to initiate communication, visibility and more business.

The name of the project is "Attrezzi Digitali" (Digital Tools) since its developer is based in Italy, but the form has English text and you can use it anywhere in the world.

Follow this instructions:

This is a crowdsourced and opendata map of tools that normally should be found in a Makers Space.
The map is to localized tools such as 3d printers, laser cutter etc… A simple way to localize the tools you have around you and to inform the world if you want to rent a tool.
The map is open for everyone: LABs, people, Makers Shops. Is possible to define if the tool is personal, for sell or rent.
If you find some improvements or bugs you can contact me at pratosmart@gmail.com.
All is based on Google Document Form, CSV data (Opendata) and OpenStreetMap.
How does it work? Simple.
  1. Fill form fields to record your tool.
  2. In address field please put at least the city and country of the tool. If you want a best geolocation put also street and number.
  3. Send your data clicking on INVIA button.
  4. On the map actually are present some commands to autolocalize yourself and share the map on socials. With the “New…” on the navigation bar you have access to the data form to add a new tool.
UPDATE: Is possible map the tools also with a geolocated tweet with hashtag #attrezzidigitali, please put a picture of your tool in the tweet and send it, it will be mapped in about 15 minutes!
The hashtag to share the idea is #attrezzidigitali
To integrate map on your site please use this code.

The Map is available here.

Here is the interactive map. The number of points changes detailed level as you zoom in or out. You can get the detailed tool information by clicking the point on the map:

Here is the image of the map at the time of this post, hopefully you will use it and increase the number of points to connect with your wider area:

How to cast pewter metal objects in 3d printed molds

Here are two examples and guides on how to cast pewter metal parts in 3d printed molds.

The first detailed guide is on Instructables and involves Lumi Pocket DLP printed mold:

Detailed guide is at:


Here is a different method presented in video by Ian Garrett who made a powder based mold on z-corp 350 3d printer:

Make your own 3d printed syringe pump for DIY science projects

Syringe pump can be expensive piece of scientific equipment that pumps out or pushes exact amount of content in unit of time from a syringe. With help of Open Sustainability Technology Lab you can now make this tool yourself for much lower cost with 3d printer and Raspberry Pi for control. This DIY syringe pump design is released under open source license.

Some version of this could be used also for medical purposes ...

FULLY 3d printable acoustic guitar that you can make on your home machine

Solstie developed fully functional acoustic guitar that is FULLY 3d printed (body AND neck) and which can be printed in parts on your home FDM 3d printer WITHOUT any supports and then glued. Only non-printed parts are strings and tuning machines.

It is playable and sounds reasonably well for a music instrument that will cost you 30 USD to make.

This is a great step forward for DIY music since most 3d printed guitars until now were electric guitars where acoustic properties of a body material don't matter and were printed on commercial machines. Necks were rarely printed.

All files are available on Thingiverse:


You don't own a 3d printer but you want to 3d print something? Now you can with 3DPrinterOS!

As a part of pre-release promotion and testing the people behind 3DPrinterOS enable everyone to use 3d printer of one of the team members via their software web interface.

From their release:
Prior to the full release of 3DPrinterOS, you can sign up and test out our software.

For those without 3D Printers who want to try 3D Printing, Aaron from our team made this walkthrough for requesting access to his 3D Printer (Makerbot Replicator 2) he has in Brooklyn, NY.
We will be posting some of these prints on our site and our twitter (@3DPrinterOS).
Relevant links:
To sign up: https://cloud.3dprinteros.com/To download current software: http://3dprinteros.com/To request Aaron's printer: aaron (at) secured3d.com

I'm not sure how long will this action last, but I'm sure that 3DPrinterOS will have success in the future.

MM1 modular multimaterial 3d printer by MakerMex

MM1 is a new 3d printer by MakerMex from Mexico. The main feature of MM1 is the modularity of the extruder head that is easily replaceable and could be upgraded in the future. It is a standard "feature" of any DIY 3d printer where you can find many upgrades for your machine, make and install it yourself. I think MM1 aims at users that lack knowledge or time to learn skillset needed to make attachments themselves.
MM1 wants to achieve ability of multiple material printing with their extruder and printbed modules.

MM1 technical specifications:
  • Printer Dimensions: 49 x 37.5 x 49 cm.
  • Weight: 11 Kg
  • Build area: 20x20x20cm 
  • Filament: standard 3mm filaments 
  • Resolution: 20 microns (0.02mm) 
  • Speed: 300mm/s 
  • Supported Materials: ABS, PLA, flexible PLA, conductive material, wood-based filament, nylon, polycarbonate, chocolate, Play-Doh, ceramic, plasticine clay and much more
  • Multiple printer linking abilities using structural connector system
  • Compatible with any Windows, Mac or Linux-based operating system
  • Supports and uses open source software
  • Price: at $1,149 range

MM1 is on Kickstarter now:

The Bug is a new kind of DIY 3d printer that prints with fiber composites

Sebastian Morales developed a new kind of 3d printer inspired by fiber composites found in nature and named it "The Bug".

The printer uses fiber soaked with UV curable resin and then extruded trough toolhead with UV lights.

Sebastian writes:
"Think of this machine as a very friendly sculpting spider."

Here is the extrusion head solidifying the UV resin:

Prints are still a very rough but the concept works and is under development.

Here is Instructables page with much more details on The Bug:
