选择右3D打印机

A3D打印机uses an additive manufacturing process, i.e. it manufactures an object layer by layer: either by adding material, solidifying a liquid or powder binding. Unlike conventional machine tools that make it possible to create a part by removing material through machining, this technology creates objects by adding layers of material. It reduces production times compared to conventional machining processes and provides very high precision in the production of complex shapes.

Unlike molding techniques, which require the mold to be made before material can be poured into it to manufacture the part, 3D printers work directly from a digital file that is cut into “slices” corresponding to each layer of material.

  • 什么是主要的3D打印技术?

    技术 Principle 评论
    融合沉积建模(FDM) 3D打印机加热灯丝(PLA,ABS,PET等),使其柔软和可延展,并将其置于托盘上的连续层。

    When the part has fragile areas (for example a tray on a narrow base), it is necessary to provide support areas that will be removed after the part has been manufactured.

    Printers intended for the general public. You can use this technology for prototyping and to manufacture single parts, for after-sales service for example.

    由于打印机,所制造的部件可能具有良好的精度,但对于复杂的部件,我们建议您使用SLS技术。

    Fused Filament Fabrication (FFF)
    Selective laser sintering (SLS) The 3D printer uses a laser beam that solidifies a powder (polyamide, ceramic or glass) layer by layer to produce parts that can have a high level of detail.

    When manufacturing complex parts or parts with fragile areas, there is no need for supports as the fragile areas are supported by the unfused powder.

    当它们从打印机出来时,部件通常具有砂质外观,必须通过抛光阶段以获得良好的饰面。

    印有SLS的部件具有良好的机械性能。

    直接金属激光烧结(DMLS) The 3D printer uses a laser beam that solidifies a powder (polyamide, ceramic or glass) layer by layer to produce parts that can have a high level of detail. These printers are increasingly used in cutting-edge industries such as aeronautics and the automotive and medical fields.

    它们代表了显着的初始投资,以及高维护成本,但它们使得可以产生非常复杂的部件,机械性能与以传统方式获得的零件相当,如加工或铸造。

    电子束熔化(EBM) 3D打印机使用电子束固化粉末(钢,钴铬,铝,钛等)层,以产生非常复杂的部分,不能以其他方式制造。 制造过程在真空下进行,这防止未溶解的粉末氧化。这可以立即重复使用。

    该技术只能用于导电材料。它比激光技术(DMLS)更快但比较精确。

    Stereolithography (SLA) These 3D printers use an ultraviolet ray to solidify the resin. The parts obtained are very precise and have a very good surface finish.

    对于原型制造和模具制造,其速度尤其理解这种技术。

    数字光处理(DLP) This technology uses a projector that does not need to move horizontally and makes printing faster than SLA.
    PolyJet These printers combine the emission of ultraviolet light with the projection of micro-droplets of photopolymer material (which hardens under the effect of ultraviolet light). This technique makes it possible to combine different materials that may have different mechanical properties depending on requirements (rigid or flexible materials for example).

    它用于玩具制造和航空航天行业。

    多jet建模(MJM) 这些打印机喷射液体材料,然后将其凝固凝固。它们配备了多个打印头,其中一个用于与零件的同时创建材料(例如蜡)。 The parts produced are very precise and can be made of multiple materials depending on the number of print heads.

    This technology is especially used in jewelry making and mold manufacturing.

    用于建筑物或土木工程的3D打印机也使用喷涂。

    粘合剂喷射

    粉末结合

    这些打印机将粘合剂喷射到粉末施加的层上层的粘合剂。 利用这种技术,可以产生非常复杂的彩色零件。但是,必须通过吹制或吸尘去除多余的粉末。

    The first 3D printers were used in industry for prototyping, but themedicaldental行业迅速对这种技术感兴趣,这对于生物印刷(蜂窝织结构制造)和用于制造假体的技术。

    Industries linked totransportation航空,aerospace,shipping汽车与传统制造的部件相比,部门也可以使用3D打印越来越越来越多地使用3D打印,这使得可以获得具有等效或甚至改进的特性的较轻的部件。

    该技术也广泛使用建筑civil engineeringfor the production of models as well as in the direct manufacturing of buildings or structures such as bridges.

  • 3D印刷技术有哪些优势?

    The main advantage of 3D printing is that it can work directly from a CAD file (a 3D file produced by a design office, for example) using a minimum amount of material, unlike traditional machine tools, which generate a lot of chips or shavings that must then be recycled. This kind of manufacturing also doesn’t require lubrication, which greatly limits the risk of pollution.

    3D打印的另一个优点是能够使用传统工艺(加工,锻造或铸造)来实现具有非常复杂的形状的零件。此外,3D打印机允许创建越来越大的零件。首先用于对原型设计,3D打印现在允许通过能够制造具有轻微差异的零件以及以竞争性价格制造零件的零件来进行大规模定制。通过高速3D打印,生产时间越来越减少。这使得可以在较短的术语中考虑生产中型或大系列。

    部分的视觉方面是与3D打印的某些方面有关的少数问题之一。如果在成品上可见部件,则必须首先进行抛光。但如果它们是隐藏的(例如,齿轮),它们将不需要完美的饰面,并且可以像它们一样使用。

    Advantages of 3D printing:

    • 降低生产成本
    • Reduced manufacturing time
    • Fewer errors
    • 按需生产

    3D打印是一个不断发展的市场。第一3D打印机仅限于使用单个材料并设计成产生非常小的物体。产生的部件没有强大的机械性能。今天,我们正在看到多材料打印机的出现和可以产生非常大的物体的那些。无论是在医疗领域,在工业领域还是在建筑中,我们都可以期待这些机器即将为移植或完全多材料产品创建完整的器官,这些机器人直接奏效。vwin德赢官方网站3D印刷市场之一是维修市场。主要家用电器制造商提供了使用这种技术制造的备件。

    混合机器也在出现时,将3D打印头组合在使用例如WAAM(电线弧添加剂制造)工艺的数控机器上,这是用于生产钛部件的沉积焊接工艺。

    消费者市场正在迅速增长,对制造商表示重大份额。长期可能与Fab Labs进行竞争,提供与3D打印服务一起提供的建议和服务。

    On an industrial level, printers are emerging that make it possible to work with highly technical materials and that are capable of producing large parts. From now on, manufacturers are offering 3D printing services in addition to selling the machines. Their printing centers make it possible to use different printing techniques without having to bear the cost of investing in the machines themselves.

  • 3D打印机的价格是多少?

    为了比较3D打印机的价格,有必要区分为公共和工业机械的机器。工业和消费者3D打印机通过其印刷体积,准确性,印刷速度,声级和所用材料来区分。

    On the consumer market, FDM printers that print in PLA monofilament with a maximum volume of 200 x 200 x 200 x 200 mm and an accuracy of 100 microns can be found starting at €300.

    在专业市场上,在PLA或ABS双丝中印刷的FDM打印机,最大体积为200 x 200 x 300 mm,可从4000欧元开始。
    对于立体光刻打印机,您可以预期支付10,000欧元和150,000欧元。
    For printers that allow you to create metal parts, you can expect to pay over €100,000.
