DIY 3d printed tray for professional pick and place machine




Parker Dillmann needed a custom tray for electronic components to be served to his DP2006-2 Madell pick and place machine, so he designed them and 3d printed them on MakerGear M2 in PLA.
The tray works under realistic conditions.

Static electricity could be a problem on such PLA plastic tray, so solution would be to paint it with some antistatic coating or use different material. Maybe some type of conductive ABS treated with acetone smoothing to reduce fine electronic parts getting caught in the layers.

Similar trays could be probably adapted for different types of pick and place machines and probably all types of electronic components. This would be great opportunity for companies in the field to cut the cost or deliver 3d tray models with their machines or components.

Retro Populator open source kit will turn your 3d printer into pick and place machine for home manufacturing










Retro Populator is an open source project by Eric Boyd that developed a kit for your 3d printer to convert it into pick and place machine suitable for small scale home electronics manufacturing.


Project description from hackaday.io:
A jig and software for allowing a 3D printer to do electronics pick-n-place assembly. It populates boards, by retrofitting a 3D printer, hence Retro Populator.

Motivation: surface mount soldering is great, but the process of placing parts is tedious and requires great manual dexterity as well good vision. Doing a few boards by hand is practical, but doing more than about 20 is hell on earth. Yet it's not practical (read: affordable) to pay industry to do it until about 500 boards - the setup charges just kill you. So there is this huge chasm between what's doable for hobbyists by hand, and where industry can take over, and this volume is commonly desired in the maker community - a small run of 50 to 100 boards is in fact typical. Thus, the desire to build machines that hobbyists can own to do electronics pick-n-place. Our cost-saving idea is to retrofit similar machines that makers already own: 3D printers.

Team:
Rob Gilson
Adam Evenden
Charles Hartlaub
Eric Boyd
There are several versions of Retro Populator being developed:
Version 1.0 : Essentially complete now. CNC milled acrylic base plate, with milled tape holders. Vacuum syringe for picking up parts, vacuum supplied by SMT rework station. Milled nozzle mount which attaches to the side of the existing extruder. Z-axis rezero jig to easily change re-zero height. 3D printed cam-lock parts to holds boards in place on 10mm peg-grid base. Code parses a yml file for board & tape placement info, and then an eagle .brd file directly for part types and locations. It generate a gcode file which goes from pick to place location for all of the parts which can be populated. Support for
multiple boards.

Version 2.0: currently in planning/design. Addition of tape advancement, including plastic cover peeling. Addition of a second nozzle which will do solder paste dispensing. Software will have 'position confirm' feature where it will move to the corner of each board, and the first component on each tape, so that you can verify key locations directly before running the entire job.

Version 3.0: part rotation. Numerous other things we'll learn about as we do V2.0, no doubt...

Maybe we will soon have thousands of small electronics factories in garages competing with corporate sector ...
But first who should be afraid of this competition are companies like Adafruit ... they are in the same market as those "hobbyists" ...

Hacking your 3d printer into home manufacturing solder paste dispenser






"Jake" and "hzeller" developed a project where KiCAD (open source electronics board development software) files are converted into g code to enable solder past dispensing with a DIY 3d printer on electronic boards.

They hacked a Type A machines printer into home manufacturing solder paste dispenser. The dispenser uses solder paste (aka. solder cream) applied trough syringe with air pressure. The team behind the project still has not released hardware specifications and details.

This project is interesting since it could enable anyone to make low cost desktop home manufacturing station and produce series of electronics boards.

The syringe dispenser pressure unit can be done at home workshop, here is a different project for reference:

https://www.sparkyswidgets.com/portfolio-item/diy-solder-paste-dispenser/

Solder paste is heated after dispensing on electronics board surface to melt and fuse the conection closing the electric circuit.


Here is the original code for solder paste dispensing that converts KiCAD files to g-code:

https://github.com/hzeller/rpt2paste

the project is further developed to include pick-and-place capabilities:

Now you can start your own small desktop electronics factory :-)





Airwolf3D releases Wolfbite ABS chemical print surface adhesive




Airwolf 3D released their chemical ABS filament adhesion product that is applied on glass print bed and vastly improves its ABS "stickiness". My impression was that the technology is moving away from adhesives in juice, glue or spray form and towards more high tech print surface materials. Still, there must be a market niche for this even in the future.


From video description:
Airwolf 3D is proud to announce a new solution for adhering ABS straight to the glass on the bed of most 3D printers. No more warped, cracked or peeling parts. Apply one thin coat to the glass and it will last several prints. Water soluble, so cleaning is easy. Use Wolfbite to get better adhesion to the glass with ABS, and also to easier release parts from the glass when done printing
There is no information on the composition or ingredients of the Wolfbite.

It is priced at $19.95

iBox Nano SLA 3d printer is best in EVERYTHING except print volume and purpose





It's the world's smallest 3D printer, it's the quietest, simplest and most affordable 3D printer on the market. It has EVERYTHING ... well ... except printvolume ... or purpose ... I really don't see the usage scenario. Maybe for some specific hobby or modelling applications. Still it is a interesting small machine.

Here are the technical specifications and key features:
  • Printer Technology: Stereolithography (LCD)
  • Build Envelope: 40 x 20 x 90mm

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:
