3D PRINTING & MODEL MAKING
MedTec’s roots began with model making and it’s something we continue to do today- now with the help of our state of the art 3D printers.
Using multiple Ultimaker 3 Extended printers (which are the most reliable dual extrusion 3D printers available), MedTec can achieve complex designs with improved 3D print performance. A 3D printed prototype a perfect way to showcase your idea in any design meeting, physically demonstrating your design intent, prompting discussion and providing the chance to identify any potential design issues from an early stage in the design process.
Alternatively, 3D models of your final design is the perfect sales tool and great to keep as a record for any further design iterations.
Materials We Use
Key Features: Good tensile strength and surface quality, easy to work with at high print speeds, user-friendly for both home and office environments, PLA allows the creation of high-resolution parts. There is a wide range of colour options available.
As above but from a recycled origin.
Key Features: Excellent mechanical properties and interlayer adhesion, nice aesthetics, minimal warping and reliable bed adhesion.
Key Features: Industrial-grade impact and abrasion resistance, durable, high strength-to-weight ratio, low friction coefficient, and good corrosion resistance to alkalis and organic chemicals.
Key Features: Durable with high toughness and fatigue resistance (PP retains its shape after torsion, bending, and/or flexing); low friction and smooth surfaces; good heat resistance (up to 105 ˚C); semi-flexible; chemical-resistant to a wide range of bases and acids, including industrial cleaning agents; high electrical resistance; very resistant to moisture; translucent; low density resulting in lightweight parts (high strength-to-weight ratio); excellent layer bonding
Key Features: Exceptional wear and tear resistance, high impact strength, Shore-A hardness of 95, up to 580% elongation at break, and good corrosion resistance to many common industrial oils and chemicals.
Using Recycled Materials
At MedTec we use a recycled PLA 3D printer filament which still boasts the same great PLA features such as; low warping, limited smell and premium print quality – but with the added benefit of being produced from factory waste streams as opposed to virgin pellets.
We can feel good about reducing the demand for natural resources and therefore saving the environment, whilst being confident that the print quality will still be one of the best on the market.
3D Printing & Model Making Case Study
3D printing has been around for a while now, but what is up and coming are the materials you can now print.
MedTec have recently just finished working on a 1930’s motor yacht, modeling in the major 3D routing systems on the boat. When they heard we had a 3D printer, they asked if we could produce some flexible bespoke ducts. We used a semi flexible material called TPU 95A which has exceptional wear and tear resistance, high impact strength, up to 580% elongation at break, and good corrosion resistance to many common industrial oils and chemicals.
First off we printed some thickness trials to ascertain what would be good for the flange and sides of the duct. The next obstacle was the size of these ducts, as they were larger than our 215x215x300 build volume. They were modeled as whole items, we then set about slicing the 3D model up so they would fit inside the build volume.
The next task was to join the 3D printed parts together, having a temperature controlled soldering iron we plastic-welded the parts together, having the dovetail joints proved to be very strong. Feed back from the installation team was very positive.
