Cool Veterinary Model

This veterinary model of a blood separating device is a great example of going bigger in scale than the real thing. Not all scale models need to be small. In this instance the model is 6X bigger than the product it is replicating. By going bigger, the details of how the product works can be featured clearly.

This separating device takes blood and breaks it down into plasma and platelets in order to harvest white blood cells. The challenge of this veterinary model was to show the process in a clear and user friendly way.

Our model makers chose colors to represent the different processes. Yellow = plasma. Red = blood cells.

A clear acrylic tube was used to represent the flask. A silicone vinyl hose was placed inside, which gave the correct diameter and coil for the extracting piece. Colors were added using theater jells.

The resulting veterinary model looks cool and communicates the properties of the separator with accuracy.

Hip Implant Device Makes for a Beautiful Scale Model

Often times at KiwiMill a scale model turns out to be a work of art in itself. An excellent example of this is the Taper Fill Hip System. This product is an implant that is inserted into a person during hip replacement surgery.  When made into a model at 3-4 times its original size, the beauty of the design and its functionality really come to life.

Modular scale model

The model was commissioned to show how the implant works inside a human body. The various parts of the device were created in a modular fashion, so they could be taken apart and put back together during a demonstration. Model Maker Mike chose magnets to connect the various pieces of the implant to each other. This makes it easy for a salesperson to connect and reconnect them over and over again.

The various parts of the scale model were made from 3D printing and CNC milling and routing. The finishes were particularly important in this model build, as they illustrate how the product functions. For instance, the heavily textured areas that you see in the model are used in the real product to encourage human tissues to attach and grow after implantation.

The high gloss on the pink socket you see in the model is a mirror-like finish, achieved by placing a clear coat  over the painted surface. The shiny chrome surfaces you see in the model were created using vacuum metalization.

All of these carefully rendered surfaces come together to create a an incredibly visually appealing scale model. The modular features of this particular model only add to its usefulness.

Medical Product Models for Trade Show

Product Model Hip Implant

Product Model Shoulder Implant

Product Model Knee Implant

Recently KiwiMill model maker, Mike, took some time out to share with me the processes he went through with three medical product models he created.

The product models were 3 1/2 x larger versions of medical implants. This human-friendly scale allows potential customers to view the design and structure of each implant in a trade show setting.

Mike used a combination of processes and materials for each model. Tooling board was carved out with the CNC router to form the core of each model. 3D printing was used for some individual parts. Extensive amount of effort went into the finishes on the models.

Vacuum metalized chrome was applied to several parts along with texturized paint finishes. One of the models required custom mixed pink color that was given a durable clear coat on top of the paint for a mirrored finish.

Two of the models were modular. The shoulder implant model consisted of a stem, neck, head and pegged glenoid. Each piece fit into the next. The top piece was held on with magnets.

The hip implant model had a stem, head, cover and liner that were removable.

The final medical product model, the knee implant, was static.
