BetaSolution

Now your 3D-prints are one step closer to the ones of professional 3D-printers because 2PrintBeta proudly presents:

BetaSolution



BetaSolution is a chemical solution which was especially developed to work as a solvent for polylactic acid (PLA) without harming acrylonitrile-butadiene-styrene (ABS) which is a proofed material to print with.
This allows to use PLA as support material when printing your object with ABS.
Since skeinforge generates support material - if needed with a header - it is possible to bridge overhangs and fill hollow space.
The removal of the support material is a mess because in most cases it consists of the same material which is used to print the object. The parts where much support material is needed don't look very nice after cleaning.

The usage of two different materials is a big advantage when printing difficult objects which should look nice although being printed with support material. BetaSolution allows to dissolve the PLA completely without harming the shape or the color of ABS. Hollow items can be completely filled with support material without the mess of it's manual incomplete removal:

After treatment with BetaSolution the example object looks like this:

 

 

How to use BetaSolution and how it works is described in the manual or in the following link.

If you want to buy BetaSolution follow this link.

Please note: You need an upgrade on your 3D-printer to print with two different materials!

BetaSolution contains chemicals comparable to the ones in drain cleaner or nail polish remover and thus treated as dangerous good. Until now it can not be shipped with all delivery services and only to certain countries.

Support - Full Disclosure

Here we proudly present to you the full disclosure of our support solution for 3D printers.

As we earlier reported, we developed a chemical solution to dissolve PLA support structures without harming an object printed in ABS. The object is put into the solution and with gentle warming and stirring or mixing with an ultrasonic cleanser bath the PLA dissolves in a short time.

The testobjects:

...before:                                                                        ...after:

You can read more about this process in our earlier reports which you can find in the support category.

Now on to the details. The solution, which we named "BetaSolution" consists of the following chemicals:

Be warned that the following chemicals are all dangerious, so handle them with care and with the proper safety precautions !

  • Propan-2-ol
  • Potassium hydroxide
  • Aluminium hydroxide

We used technical propan-2-ol (98%) but you can also use pure propan-2-ol, 8.3% Potassium hydroxide (w/w) and a small catalytical amout (<1%) of Aluminium hydroxide.

A short manual how to prepare the "BetaSolution":

For preparing the solution we gently warmed up the technical propan-2-ol in a waterbath to a temperature of about 40-50 °C. Be sure, the flask containing the propanol is not completely closed because of the rising vapour pressure. We used a flask made of glass with a perforated cap to prevent condensation of water and evaporation of propan-2-ol. After this, we took the flask out of the waterbath, dryed it from the outside, removed the cap and put the Potassiumhydroxide into it in small quantities. After each portion we stirred. The last little portion consists of about 0.5 g aluminium hydroxide which should also dissolve.

The solvatation of potassium hydroxide and aluminium hydroxide in propan-2-ol needs time. You generate a saturated solution, so don't wonder, if it gets cloudy after cooling or takes much time to dissolve completely.

Store the resulting solution safely, out of reach of children in a glass container at a dry and cool place. If you use a plastic flask it might deform or the solution will react in another way with the flask.

For use, pour a small amount into a glass, so that your object is completely submerged in the solution, and wait for the PLA to be dissolved. Please only do this in a well ventilated area or outside, because the solution will give of flammable fumes. Dont smoke while doing this !

If you want to speed up the dissolving process, you can warm the solution with a water bath (NO open fire), and stir it with a ultrasonic cleanser or manually with a spoon. This will greatly improve the speed of the dissolving.

Please wear gloves and glasses when handling the warmed solution. It is as agressive as drain-cleanser!

After dissolving the PLA you should wash your 3D-model with much water. We recommend to put it into another flask containing pure water and let it stand there for another hour. After this, you can dry it on air or with a hair blower.

The solution shouldn't be disposed into drain without dilution! Let it cool to room temperature, if warmed, and gently put small quantities into a 5 times bigger amount of water. Now you can easily use it as drain-cleanser!

For added information, you can download a safety datasheet we preprared from here

Also we are now opening an onlineshop, www.2printbeta.de, where we plan to sell this solution and other reprap related parts after we get the neccessary permits from the government. So if you are in europe, stay tuned to get the BetaSolution directly from the inventors.

When releasing in december, we also provide a more detailed german and english manual how to use BetaSolution.

To the DIY community:

Have fun with the developement of a smart software to create suitable support structures! Have even more fun with printing and dissolving the generated two-component-objects to obtain a clean ABS structure with overhangs and bridges as much as you want!
