Arbroath Twist Vase

Step 1:  ​3D print your outer bowl

Firstly you will need to 3D print your outer vase in PLA filament.  You can download a version of the file here:






Step 2:  Sprue up your vase


Firstly ensure you have a flask big enough for the vase.  Add in wax sprues ensuring that all the channels from the top of the vase are connected.















Step 3:  Invest plaster

Place your metal flask over the rubber base and your vase.  Wrap paper around the outside so that when you add in the plaster it doesn't run out.  Mix up your plaster, pour into the mould  and place into a vacuum to remove any air bubbles.


Step 4:  Casting


Place the mould into the kiln over night  so the wax  and PLA burn out.  I found that in some cases of casting from PLA there was holes in the work.  To combat this I blasted pressuried air into the mould before casting into it.  This seemed to remove most of it.


Place the mould into the casting machine (still hot) and allow the temperature of the casting machine to rise to the aquired level.     Pour the metal into the flask and allow to cool for a few minutes.



Take your flask out of the casting machine and quench in water.  Most of the plaster should come away and you should be able to take your casting out of the flask.


Step 4:  Ultrasonic


Place your vase in the ultrasonic machine with a cleaning liquid ( I used vineger).  This may need to stay in a few hours to remove all the plaster.


Step 4:  Remove sprues


Using a piercing saw, cut off and remove the sprues.  File down the top of the vase until you can't see and marks or bumps from the sprues.


Step 5:  File and sand


File the outside of the vase using a large flat file.  I removed the texture of the 3D print from the outside, however, I left it visible on the inside to save filing and to also give a contrast.  Once you have removed any of the large marks use emery paper and sand up.


Step 6:  Inside sleave


























































how to make your own Arbroath Vase

Info:

There are two different sized bowls available in this series, 180mm and 89mm width.  Files are available to download below:


180mm:


Laser cut bowl file


Press form file



89mm:


Laser cut bowl file


Press form file



Why make a Laser cut bowl?


Laser cutting can be used as a very quick and accurate means of production when cutting multiple flat parts.  It is much quicker that more traditional means of cutting with a saw and leaves a much neater edge.  It leaves out the need to file and sand and polish the edges for hours on end.  The laser leaves a very smooth and shiny finished edge. 


These traits lead them selves well to producing accurate press forms.  Without the laser cutter a more traditional means of making a press form would be to hand pierce a thick sheet of acrylic and then file all the saw marks out at a 90 degree angle.  It is much quicker to laser cut multiple sheets of acrylic and glue together and the finish of the edges can be much neater depending on your filing ans sanding skills.
