Semi-Transparent SLA - 3D Printed Mr Cadbury Bust in Cadburys Boardroom.

Semi Transparent SLA Bust of Mr Cadbury

A Larger than life Semi-Transparent SLA - 3D Printed Mr Cadbury Bust in Cadburys Boardroom.….

In brief

MNL produced a modern take on Cadburys bronze bust that stands outside the Bournville Factory in Birmingham.

Model requirements….

The piece of art needed to be of a high gloss finish with a clear sweet wrapper appearance. The Cadburys purple had to be true to life, not a shade different. The piece also had to be an exact replica of the Bronze that stood in the grounds of the Bournville factory.

Filled to Capacity

The bust filled the 3D envelope of one of our large frame SLA machines. It was so large that we had to position the bust such that the shoulders were across the diagonal of the 500x500mm platform.

Sweet Wrapper Look

The bust was hollowed out and hand finished on both inside and outside surfaces. The inside was spray painted Cadburys purple whilst the outside was given several coats of gloss lacquer to achieve that lustrous look.

Urgent Timeline

Scaled down simplified data of the engineering plant was broken down into many sections representing the differing areas of the plant. Several SLA printers and SLS printers were utilised simultaneously to speed up the process.

Urgent Timeline

Once the pieces were built, supports were carefully removed. As budget was limited, parts were given a light sandblast and a quick coat of paint, the colour depicted the various sectors of the plant.The parts were mounted to a custom built display board. All in all the project was completed in just over a week

How it was achieved…

3D data was captured at the Bournville site with laser scanning equipment. The resulting data, once tidied up, was hollowed out to a 4mm wall thickness to give the piece some strength.
The data was processed ready to be built on one of our large frame SLA machines. The bust filled the 3D envelope of one of our large frame SLA machines. It was so large that we had to position the bust such that the shoulders were across the diagonal of the 500x500mm platform. The automatic support generation software provided reliable supports as the Stereolithography [SLA] machine embarked upon the 3 day build.
The finishing stage was the most crucial as the high quality standards expected had dictated the use of our most trusted finishers/sprayers. The inside was spray painted Cadburys purple whilst the outside was given several coats of gloss lacquer to achieve that lustrous look the client had specified.

Detailed Views

The underside of the nose just about shows the clear wall thickness of this magnificent piece.

e-Stage automatic support generation created reliable supports shown here under the nose and moustache.

Attention to detail and pushing the boundaries of processes and techniques is a common thing here at MNL. For this project detail and surface finishing were critical. Getting the correct shade of purple; essential.

Why MNL?….

One of the key facts for using MNL expertise was quality. Utilising MNLs in house large frame 3D printing system, the SLA bust was produced in only a matter of days.
Only master finishers with 20+ years of experience each were allowed to work on the critical stages of the finishing to give that look the client so desired.
The entire project was completed from data to desk in a littlet over a week.

In conclusion….

Almost anyone can 3D print a model it’s what you do with it after is where MNL stands out from the crowd, with a selection of 3D Printing processes and a skilled model making team, make for a perfect project partnership.
