Recently, three British design companies have teamed up to create a titanium alloy 3D printed bicycle frame with a weight of less than 1kg. 3D printing company Mirada Pro, bicycle tube expert Reynolds Technology, and frame manufacturer Ted James all contributed their knowledge of the frame and reduced their weight using topology optimization software.
Do you think that the additive manufacturing of sports is starting to get you bored? It won't happen now, as three British design pioneers are preparing to launch a most forward-thinking bicycle component in recent years: a 999g 3D printed titanium frame. The expert in making the frame is Mirada Pro, a Birmingham metal 3D printing specialist who is currently focusing on the bicycle industry; Reynolds Technology, also from Birmingham's steel pipe business, has been serving bicycle enthusiasts for more than 120 years; Ted James, from Manufacturer of bicycle and BMX frames in Stroud, Lochester County. Together, they combine their areas of expertise to create a topology-optimized frame that accelerates the use of 3D printing in bicycles.
From design to manufacturing in just eight weeks, this 3D printed frame is impressive. It is understood that although these British designers have not completely modified the wheels, their cooperation has the hope to make the most important contribution to the ever-expanding additive manufacturing bicycle stage. The frame features a custom titanium alloy 3 / 2.5 tube from Reynolds and a 3D printing sleeve connector designed by Mirada Pro to connect the head tube, bottom bracket, lower tube and top/sit tube. The metal parts were soldered by James, and a new frame with a torsional stiffness superior to that of a conventional alloy frame was born.
The use of topology optimization software is an important factor in the weight of the frame below 1kg. By entering the required load data, Mirada Pro is able to set up CAD software to make frame parts with less material, allowing the production of products of sufficient strength to be produced with a minimum of 6 / 4 titanium alloy 3D printed powder. This reduction in material usage not only makes the frame lighter, but also saves the design company's money, which means that a molded 3D printing frame can be incorporated into the future.
“The shape is controlled by one of our computer programs,†Iain McEwan, product engineer at Mirada Pro, told Cyclist. “We put the standard load that the frame needs to withstand the safety test, enter it into the program, and tell it to generate a shape that can support these loads and use the least amount of material. In other words, if you have a piece of titanium for the head tube Alloy, you can leave the material that can support the required load while removing other parts."
The 3D print frame has not yet become a complete bike, but it has been sent to a separate test lab where it will complete the subsequent test steps. If the results indicate that the frame is suitable for cycling, the three designers may one day create a 3D printing frame suitable for mass production.
Dog Crates is a kind of Pet Cage. The surface treatment of cages are plastic spraying, plastic dipping, electrophoresis, chromium plating, galvanizing, imitation gold, etc.
There are mainly the following types,
1. Detachable Pet Dog Fence type:
It's simply to surround and limit the range of activities of the little guy. The mother dog and the baby dog can be isolated together to avoid injury. Or put it in the yard for little dogs to play, limiting the scope.
2. Folding Pet Cage type:
The light and foldable cage is suitable for people who don't have much space at home. This is suitable for some small dogs or puppies.
3. Heavy Duty Dog Cage type
Weight type, always at home. It is suitable for medium and large dogs and is durable.
The role of dog cages.
1. Convenient for cleaning
Prepare a cage at home to let dogs get used to living in the Dog Kennels Cages, which can greatly reduce the behavior of dogs excreting at home, and it can also be more convenient for owners to clean.
2. Provide a safe space
Dogs are cave animals. Compared with open space, narrow cages are more suitable for dogs, because they can make dogs feel safer.
3. Isolate dogs from people
For example, when guests come to the house, because dogs are still a little wary of strangers, in order to appease guests and dogs, dogs can be temporarily caged.
4. Avoid dogs tearing down their homes and correct their behavior
When the owner is not at home, the owner had better keep the dog in a cage, which can avoid the dog's behavior of tearing down the house, and can also correct the dog's random biting behavior. If the dog is biting during the tooth change period, the owner can give the dog a bit of molar snacks or Pet Chew Toys to bite and reduce the pain and itch.
5. Reduce random eating
Another advantage of keeping dogs in cages when they are alone at home is to prevent dogs from eating indiscriminately.
Therefore, it is better to prepare a dog cage at home and use it at an appropriate time. When you are usually with dogs, it is recommended to do more training for dogs to improve their obedience. If you perform well, you can give some dried chicken as a reward, so that you can clean your teeth while training.
