Technical field
The utility model relates to a kind of device that polymeric material 3D prints intensity that improves, and belongs to 3D printing technique field.
Background technology
3D printing technique is called again " rapid shaping technique ", is also referred to as " increasing material technology ", " accumulation technology ", is the advanced manufacturing technology growing up nineteen nineties.3D printing technique is to take three-dimensional digital model as basis, adopt discrete accumulation principle, according to certain thickness, by three-dimensional digital model, divide layer scattering, form a series of two dimensional surface model datas, again data are carried out to certain processing, add technological parameter, form numerical control program, under digital control system is controlled, in plane machining mode, process continuously each thin layer, and make it bonding and moulding.
For using polymeric material to carry out 3D, print processing, adopt fusion sediment moulding (the Fused Deposition Modeling of thin layer paving powder mode, FDM) by material self, complete the method that bonding realizes solid forming comparatively ripe, but the subject matter running into is to increase to rely on the principle of resin self gravitation infiltrated with molten metal bottom surface to realize shape because every layer of material accumulation is bonding, in infiltrating lamination process, easily form the weak connection such as entrained air bubbles, hole, cause the toughness of material of product product and intensity all not enough.
CN201320511128.5 has proposed a kind of press fit device, can print the polymeric material of extruding to 3D and exert pressure, but the pressing plate that the method is used has larger side-friction force to the surface of the application of force, easily causes material breaks and comes off.CN201410002890.X adopts hyperbaric chamber and high-pressure pump to apply free of discontinuities high pressure to printed product and obtains dense material, but the hole that material stacks forms easily can not be eliminated due to pressure balance, therefore also inapplicable for the fusion sediment moulding of paving powder moulding.
Utility model content
The purpose of this utility model is to overcome prior art deficiency, and a kind of device that improves the density of the stacked direction of material, effectively overcomes the defects such as bubble, hole, raising 3D printing polymeric material intensity is provided.
Technical solution of the present utility model: a kind of device that improves polymeric material 3D printing intensity, comprise framework, laser thermal source and backer roll, laser thermal source and backer roll are arranged in the lower surface chute of framework by laser support arm and backer roll support arm respectively, the driving mechanism can make it move along X, Y and tri-directions of Z is installed on framework, backer roll with after vertical contact of the unhardened polymeric material of laser thermal source heating and melting, pressed polymeric material, in short transverse, the unhardened polymeric material of melting is exerted pressure.
Described laser support arm can move along directions X in the chute of the lower surface of framework, and highly adjustable in vertical direction.
Described backer roll support arm can move along directions X in the chute of the lower surface of framework, and highly adjustable in vertical direction.
The utility model beneficial effect compared with prior art:
(1) the utility model adopts backer roll, in every polymeric material melting process, increased pressurized step, can effectively reduce the bubble, hole of interiors of products, the weak defect such as bonding, improve the strength and stiffness of interlayer materials, be particularly suitable for using on 3D equipment for the polymeric material that has granular filler or short fiber to strengthen;
(2) between laser thermal source of the present utility model and backer roll, distance is adjustable, and vertical height is adjustable, can be according to polymeric material and the shape adjustments correct position of wanting moulding, strong adaptability;
(3) driving mechanism that the utility model utilization is moved along X, Y and tri-directions of Z can be adjusted arbitrarily heating and pressing position, simple to operate, can be suitable for continuous production.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing and example the utility model, be elaborated.
The utility model as shown in Figure 1, comprise framework 1, laser thermal source 2 and backer roll 3, laser thermal source 2 and backer roll 3 install 7 in the chute of the lower surface of framework 1 by laser support arm 6 and backer roll support arm respectively, the driving mechanism can make it move along X, Y and tri-directions of Z is installed on framework 1, backer roll 3 with after vertical contact of the laser thermal source unhardened polymeric material 4 of 2 heating and melting, pressed polymeric material 4, in short transverse, the unhardened polymeric material 4 of melting is exerted pressure.
Laser support arm 6 and backer roll support arm 7 can move along directions X in the chute of the lower surface of framework, make the horizontal range between laser thermal source 2 and backer roll 3 adjustable, laser support arm 6 and backer roll support arm 7 are highly adjustable in vertical direction, can be according to polymeric material and the shape adjustments correct position of wanting moulding.
The utility model principle:
Polymeric material is made to fine powder, use 3D printing device to form even thin layer (polymeric material 4) at Workpiece shaping carrier surface.Utilize 2 pairs of selection areas 5 of laser thermal source to heat, make polymeric material 4 meltings in selection area 5, infiltrate the carrier surface of lower floor, then remove laser thermal source 2, when polymeric material 4 still keeps melting unhardened, with backer roll 3, pressed this selection area 5, squeezed away bubble, and made the material internal in selected region 5 fine and close.Cycling can make polymeric material 4 interlaminar strengths of 3D printing shaping be significantly improved.
The utility model workflow:
Prepare polymeric material as polyester, polystyrene, Merlon, ABS, polyvinyl chloride, polyamide, polyimides etc. separately or the fine powder of the polymeric material of the polymeric material mixing and adulterated inorganic particle, inorfil or carbon fiber, the granularity of fine powder should not affect sprawling of thin layer.Use 3D printing device to form even thin layer at Workpiece shaping carrier surface.Utilize thermal source (as laser) to heat selection area, control heat time and power and make polymer material layer melting in selection area but non-sclerous, the mobility of polymer should guarantee to infiltrate the carrier surface of lower floor.Then heat source is shifted to next heating selection area, and backer roll and thermal source move in the same way simultaneously, and backer roll itself can provide certain limit adjustable grinding pressure, and can be along fixed axis axial-rotation, when polymeric layer still keeps melting unhardened, use pressurization roll-in to cross this region, squeeze away bubble.Backer roll height is adjustable, by short transverse, regulates, and the height that makes melting layer is the original 0-90% of boil down to as required, makes the material internal in institute's nip territory fine and close.By this operation, fine powder is formed to new even thin layer on Workpiece shaping surface.Utilize thermal source to heat selection area, make the polymeric layer melting in selection area, infiltrate the carrier surface of lower floor, then, when polymer still keeps melting unhardened, this region is crossed in pressurization roll-in, squeezes away bubble, makes the material internal in institute's nip territory fine and close.Recycling the polymer material layer that just can realize 3D moulding and interlayer has good contact and bonding, improves the intensity of goods.
The unspecified part of the utility model is known to the skilled person technology.
