Devon 3D CAD is exploring a new niche market of 3D CAD design of Spectacle Frames .
I am excited to be using my modelling skills in SolidWorks to create new spectacle frames for clients. Most people who wear glasses have a number of pairs to suit their style of dress or a special occasion. They choose the material, the colour, how the lenses are supported, the shape of the arms, how much decoration is used, and many more variables.
Materials, Finishes and Styles.
At the moment I am modelling designs in plastic. I am building the nose pads into the frame. The arms are a composite of metal and moulded plastic. The hinges all use the same principle but with different details. Another Design of Spectacle Frames uses a slender metal frame to encase the lenses, metal hinges and metal arms. I am building up a range of designs to demonstrate how the different features work together.
3D Printing of Spectacle Frames.
3D Printing is now mainstream and is a great way to test out the Design of Spectacle Frames. Get a fast turnaround time and a cost effective price.
Not many people have perfect vision, and most of us, at some time or other, need a pair of Spectacles.
Gone are the days when all you could get were Harry Potter round lenses with wire arms. Today there is a dazzling array of designs at every price point. I like the challenge of designing Spectacle Frames because they fulfill an obvious need but can be fashionable at the same time. The challenge I set myself was to model, as faithfully as possible, a range of Spectacle Frames in a variety of materials and shapes.
This pair of spectacles has a moulded plastic frame and also moulded plastic arms. They are joined with industry standard steel hinge parts that are inserted into the plastic parts during manufacture. I would love to have the opportunity of designing frames but no volume manufacturers exist in the UK. My local high street optician tells me that they are all manufactured in Turkey, Hungary and the Far East. Undaunted, I hand measured the shapes and sizes of the frame and arms and modelled them in 3D using SolidWorks. The challenge is that all the parts are made up of compound curves. My first attempt at modelling the frame was only partially successful, the nose pads could not be modelled onto the bare frame. Second attempt was much better. I altered the order in which certain features were constructed, and this time the nose pads appeared in the correct place and I could run fillet rads around all edges of the frame.
I modelled the arms in the same manner, using a compound curve for their shape. I modelled the hinge elements separately and attached them to the frame and arms. I chose the colours for the parts and gave them a 30% transparency. I set up an assembly, inserted the parts and mated them so that they moved as expected. Slight modifications to get everything lined up properly and the model was complete.
