Description
Technical field
The present invention relates to New Equipments manufacture field, and in particular to a kind of high temperature FDM3D printing devices.
Background technology
Increases material manufacturing technology (also referred to as " 3D printing ") is based on Computerized three-dimensional CAD model, by the way of successively piling up
The method for directly manufacturing three dimensional physical entity.Increases material manufacturing technology can produce arbitrarily multiple fast precise on an equipment
The parts of miscellaneous shape and structure, so as to realize " freely manufacturing ".Compared with conventional machining techniques, increasing material manufacturing can reduce processing
More than cost 20%-40%, shortens the research and development of products cycle about 80%.Over nearly 20 years, increases material manufacturing technology is developed rapidly,
Define various forming techniques and equipment.These technologies are towards Aero-Space, weaponry, automobile, mould and biologic medical
Etc. high-end manufacture field, 3 D complex structure is directly manufactured, solve the manufacture hardly possible that conventional fabrication processes are difficult to or even cannot process
Topic.Increasing material manufacturing is used as a perspective, strategic technology, and its engineer applied is very strong, and field span is big, to following manufacture
Industry, especially the development of high-end manufacture is particularly significant.Wherein fusion sediment rapid prototype manufacturing (FDM) is a kind of by various hot melts
Thread/the powder body material of property adds heat fusing extrusion technology, and it has that equipment is simple, technique is clean, operating cost is low and not
Produce rubbish, can with rapid build hollow part the advantages of.Melt equipment (SLM) compared to the selective laser for military project,
FDM printers are cheap, it is easy to promote and be applied to as early as possible handicraft, mould, the auto parts and components directly civilian work such as manufacture
Industry.But existing FDM formers are limited by firmware and control assembly, and substrate temperature only up to reach 120 DEG C, printhead
Temperature reaches as high as 280 DEG C.These restrictions cause to be presently available for the mainly ABS and PLA bi-materials of FDM printings.With
The resistant to elevated temperatures height of high intensity such as the progress of technology and the expansion of 3d printing technique applications, nylon, PEEK and polyimides
A kind of printing of performance engineering plastics necessarily trend.The research and development of matched printing device are also extremely urgent.
At present, FDM3d printing devices are controlled using surface-mounted integrated circuit.It is printhead heating, step motor control, aobvious
Show and heated on one piece of control panel with forming room.Do so facilitates the miniaturization of equipment, but powerful substrate computer heating control
Device and low power step motor control etc. mix, and have both easily caused and have interfered, while also restricting substrate and printhead
The further raising of heating power, causing the high performance engineering plastics of many high-strength high temperature-resistants cannot print.If simple
Printhead and forming room are added into thermal release, hot environment can cause the components and parts life-span such as stepper motor to decline, precision is reduced, or even
Cannot work.High temperature convection current simultaneously can also cause printing consumables to soften, and cause stepper motor power conduction efficiency to decline, transporting resistance
Increase, the phenomenons such as fracture of wire or blocking sprayer easily occur.Printing is caused to be normally carried out.Therefore, heating power and increasing are improved
Strong heat insulation effect, while not causing because of inertia or frictional resistance that excessive to cause equipment printing precision to decline be such equipment development
Difficult point.
