Progress Report

Hi all,

Apologies for not having any updates out over the last couple of months. The large majority of the work that has been done has been on screen design work and electronics engineering, meaning that there has not been much to share.

On the design side of things, we have put in a lot of work into redesigning both the exterior and mechanical design of The Porta Presso. It was necessary that the exterior design was adjusted alongside the internal changes that we have made. The render below shows our current design that our most recent prototype has been made from.

A lot of time has been spent redesigning the internal structure of The Porta Presso to support a fully battery powered unit that does not require any gas as a source of energy. With a key focus for us being portability, The Porta Presso needs to be both lightweight and small in size. The removal of the original C02 canister system has meant an increase in battery size that has involved a lot of planning, design work as well as hands-on testing to ensure that the most appropriate battery is used, and a good balance is found between battery size and the unit housing size. Whilst it is important that the battery has enough power to produce the required cups of coffee, this cannot be in excess as this would be an unnecessary size increase. 

With portability being a top focus, we have designed and manufactured a new prototype to make two cups of coffee from each preparation. This has allowed us to have both a smaller battery as well as decrease the size of the milk and water chambers. We are currently undergoing numerous tests with this prototype with the intention for our next prototype being to increase the number of coffees the machine can produce in one preparation back up to three if feasible. 


We are still working hard to come as close to the anticipated December release as possible, however, this may get pushed back into the new year. 

As always, thank you to everyone for your ongoing support.
