500 3D printed Marvin’s..  The Most frequently asked questions I get about 3D printing..

Me and my army!!

Me and my army!!

In this post I am putting together the most frequently asked questions I get about 3D printing. All answers relate to Desktop/Home 3D printing.


What is 3D printing?:

3d printing overview

3d printing overview

With the use of a 3D printer, 3D printing allows you to convert a 3d model into a real physical object.

Why 500 Marvin’s?

All 500 Marvin’s will be given out to people who have not seen a 3D printed object. Thanks to those who will be backing/supporting the launch of the new suitcase 3D printer TeeBot.

After close to two years of 3D printing,  you will  have lots of short filaments or left overs, they make up the 500 Marvin’s.

How can I get a 3D model?

Is it easy to make own design?

With a little bit of patient and learning, it can be easy and fun. Start with easy packages like sketch-up, has lots of free tutorials online. Below I show in few step how to draw a cube. The cube is the most printed object used to calibrate and show how accurate a 3D printer is.

sketchup

The Printed object turned out to be 20.03mm on one side, unless you are sending the cube to space .03mm is OK!!

Can I get someone to print my cube for me?

Someone near you in your city has a 3D printer and is willing to print for you (at a fee), search 3Dhubs.

20mm X 20mm X 20mm ==> 8cm3

Depending on your material of choice, Price range from 6 Euros up to 35 Euros for the cube. (plastic materials. eindhoven, NL). Uploaad your STL files and find a printer near you.

Can I print  it in steel, gold, brass, platinum…?

Very possible, make an advance search in 3Dhubs or head over to the big boys @ shapeways, upload your files, pay and it will be shipped to you door step in any chosen material. Precious metal 14K gold = 5,000 Euros, Platinum 15,200 Euro (date checked 3-may-2015 @ shapeways).

Should I buy a 3D printer or assemble a DIY kit?

If you are an engineering or technical student or all of these are not new to you (REPRAP, CNC zone, soldering Iron, Arduino, pliers, drills, electric saw, schema diagrams, heat shrink tube, transistors, power supply you get my point) then feel free to try assembling a diy KIT.

For the rest save yourself and your supplier some trouble!!, grab a fully assembled 3D printer, or join an assembly workshop or find some on who can help you with assembling the KIT.

I strongly suggest all engineering and technical students to assemble a 3D printer for themselves. It can be done in a group for knowledge sharing and bulk buy of parts.

Some 3D printing words and simplified meaning.

  • Layer height: Height of the layers🙂

layer

  • In-fill pattern: Fill pattern🙂

From Slic3r.org

  • Slicing software/Engine: The software that converts an 3D object (mostly in STL format) into machine coordinates a readable instructions/command (G.code)
  • Print Bed: the flat platform on which the 3D printer prints, mostly glass and aluminium.
  • Hotend: the part of the printer that melts the plastics and extrudes it out through a small tiny hole. Printing temperature can vary from 150 degrees centigrade to 300.

Most beautiful Marvin 3Dprinted by TeebotMax.

3D hubs Marvin, 

Marvin is becoming the most popular symbol for 3d printing .

We have seen him really small, big, seen in wood, seen Flexible and sometimes an army!!.

And Now….(drums rolling, music playing, and with all cheers…) I present to you the most colorful Marvin… I handed a few of them out during the RapidPro 2015 event.
And dropped a few at the 3Dhubs stand. 15 of the Marvin printed at a go on my TeeBotMax 3D printer (guarded and watch over my a Marvin sitting un the top🙂.

Changing color: TeeBotMax can be operated connected via USB to a PC/Laptop or it can be operated stand alone!! It has an LCD controller with built in SD card reader. The LCD controller has a lot of print options that can be tweaked while the printer is printing!!. (Speed, Nozzle temperature, flow rate, just to mention a few..loving RepRap!!). One of the commonly used one is the filament change menu. When you select this, the printer does the following.

  • pause the prints and remembers where it stopped
  • Lifts the z axis 10mm above your print
  • Move to X zero
  • Ejects the current filament by unwinding the extruder motor.
  • Beeps and wait for you to insert a new filament
  • To resume  just tap the controller knob and the nozzle moves back to the stored printing position to continue.

Long Live REPRAPPERS!!!

(Looking at some 1k dollar plus printer….they have no similar function!!!)

3D Printed Wall clock with lots of colors.

When our wall clock was not keeping to time, due to obstruction in the movements of the hands. We decided to hack the clock, by taking out the engine for use in a 3D printed wall Clock.
After a few hours of 3d design with sketchup…..here is the design
round

3d printed wall clock

3d printed wall clock

It took the 3d printer 4 hours to print all numbers and about 2 hours to print the base. In total 6 hours of printing.

The clock is put together using hot glue stick 12 colored pencil and lot’s  of patience .

All Materials

 

I started by sorting out which colors I want to use where. Then drop a glue in the holes before inserting the pencils.

Next  I drop glue on the tip of the pencil before inserting them into the round base.

I then insert the pencils in to the base using the hanging hole at the back as a reference guide for 12.

Next Insert the clock engine behind and installed the arms and battery. Very impressed with the pencils !!!

TeeBotMax improvements & upgrades please share you toughts

Many thanks to comment, reviews and critics from builders of TeeBotMax the first 3D printer I designed and made opensource. It has been a big source of experience for me. Over the last few months I have been 3d printing parts for friends and customers sending the complete DIY kits to enthusiastic builder majority of which are in Europe.

Are there improvements you will like to see? are you having problems with your TeeBotMax? please comment bellow or send me an email.

If you are new to 3D printing.. the question is how would you like to get involve..? Share your comments bellow.

The Positives…

  • Let’s start with the good news….
  • The design:- Many love the simple design!! Its just down to earth simple. Lots of comments on that.
  • The frame:- It is sturdy and strong. My quality test engineer (3 year old son) Has done everything possible to crash the printer… no luck. He drives the extruder head manually printing in air or just making scratches on my print surface.
  • The Documentation:- Thanks to the early builders who went through and helped in correcting many typo and measurement error.. Majority of  those who picked up the documentation latter, never had any problem following the guide.


The Negatives and plan for improvement..

  • Wiring: Personally I wished all cables and wire are hidden, depending on your cable management skills, this can be big draw back on the look of the finished printer.
  • Action..: Use  cable/ wire track, provide complete wire harness for customers, hopefully no soldering will be required to assemble the kit.
  • cable track
  • Filament spool holder:  I guess many never printed the complete spool holder. I find it not sitting rigid on the printer. On one occasion (while do demo of course…)  a whole 1kg of filament dropped in tho the printer… Also a user informed me of similar accident, he’s was bad because it broke the Y axis part holding the stepper motor.. I had to print him a new set.
  • Action…:  Drop the filament holder and make it sit beside the printer. Also I experienced that  passing the filament via a PTFE tube to the extruder greatly increases the ease of printing and reduce the force needed by the extruder to pull the filament. Meaning you can go much  faster.
  • WP_20141225_001
  • Breaking plastic parts:- The culprit here is the Y axis . The part which supports the long 8mm rods seems to be breaking off while some people tried to drill and fit the 8mm smoth rods.
  • 2-13-2015 12-21-50 PM
  • Action:– Increase the support/ redesign the complete Y axis holder.
  • Electronics:- Many builders are experienced with other Reprap machine, choice of electronics is easy for them, however many had difficulty on deciding which control board/ Electronics to use.
  • Action:  Default electronics to the use of RAMPS 1.4 (Reprap Arduino Mega Pololu Shield Arduino MEGA based modular RepRap electronics.) the documentation will include detail instruction on how to wire up your TeeBotMax 3d printer to a RAMPS board.
  • IMG_20150129_233756 IMG_20150129_233818

New stuffs:!!On my wish list are the following, I have managed to experiment with a few.

  • Auto bedleveling/ Automatic Calibration of extruder head height from print surface.  there is a wide debate on what this should be called but basically the Idea is to have the printer do an automatic calibration to determined how flat/tilted your print surface is. and then print with out you having to worry about extruder height from the print surface as shown.

inductive

  • A New spool holder incorporated with ptfe filament guide.
  • New direct drive extruder. I am loving the design of the new extruder!! simple!!

IMG_20150213_083009

  • Packaging/Boxing:there is need to have a standard packaging for the kits both the DIY and completely assembled printer.

Those are my thoughts/plan if you can’t wait until all  is ready and like to jump right in on some of the above mention  just shoot me an email or comment bellow.

TeeBotMax to go wireless!!

TeeBotMax to go wireless!!

I bought a wifi box with custom application to use on the printer. the Doodle 3D is an awesome pack that allows even kids to design and print objects from a tablet, smart phone or pc.
Over the next weeks I will be trying to configure the TeeBotmax to work with the wifi box.

J Head Pen holder.

Designing a pen folder for the 3D printer.

From time to time I like to test, calibrate and try out G codes on the 3D printer using  a pen, taking the whole extruder head out together with the stepper motor is a big  challenge. Most pen holder design online require special mount to attach them to the printer.

So I designed a pen holder the snaps on the  Jhead, requires two rubber band as suspension and fits all pen of diameter less than 12mm.

photo, images, assembly manual coming up… if you can’t wait give me a shout out I’ll  email you the raw files.
