摘要： A post-processing system is provided for cleaning and/or curing a part produced by solid freeform fabrication (SFF). The post-processing systems include a housing, a part retaining device to retain the part within the housing, and an actinic radiation source to cure the part with actinic radiation. The systems also include a fluid circulation device adapted to expose the part to cleaning fluid and/or to allow the cleaning fluid to absorb actinic radiation to permit filtration of removed build material to allow extended use of the cleaning fluid. Certain systems include a first rotating portion that can rotate the retained part about a first axis, and further systems include a second rotating portion that can rotate the retained part about a second axis. The systems also include additional features to provide safe and efficient cleaning and/or curing of parts produced by SFF.

摘要： The invention relates to a process for the manufacture of coatings by radiocrosslinking. A radio-crosslinkable composition (C) is produced first of all by mixing at least one (meth)acrylic compound (A) with a reactive diluent system comprising at least one mono(meth)acrylic carbonate (B) corresponding to the general formula (I): ##STR1## in which: R.sub.1 denotes H or CH.sub.3R.sub.2 denotes an alkylene ether or alkylene chain which has a total number of carbon atoms of between 2 and 6,n denotes an integer between 1 and 6.The composition (C) is next applied onto a substrate and is then radiocrosslinked, preferably using UV radiation.Another subject of the invention is the crosslinkable compositions (C) in which the compound (A) and the carbonate (B) are not simultaneously 2,3-carbonyldioxypropyl 2-methacryloyloxyethyl carbonate, and carbonates of general formula (I) in which R.sub.2 denotes (CH.sub.2).sub.m and in which m and n are integers such that 2.ltoreq.m.ltoreq.6, 1.ltoreq.n.ltoreq.6 and n.noteq.1 when m=2 and R.sub.1 denotes CH.sub.3. The carbonates of general formula (I) are highly photosensitive, and this allows irradiation times which are very markedly shorter than those used hitherto with mono(meth)acrylic diluents, or else makes it possible to photocrosslink in the absence of photoinitiator.
摘要翻译：本发明涉及通过无线电交联制造涂料的方法。首先通过将至少一种（甲基）丙烯酸化合物（A）与包含对应于通式（A）的至少一种单（甲基）丙烯酸酯碳酸酯（B）的反应性稀释剂体系混合来制备无线电交联组合物（C） I）：其中：R1表示H或CH3R2表示碳原子数为2〜6的亚烷基醚或亚烷基链，n表示1〜6的整数。组合物（C）接下来施加到基底上，然后放射交联，优选使用UV辐射。本发明的另一个主题是其中化合物（A）和碳酸酯（B）不同时是2-甲基丙烯酰氧基乙基碳酸2,3-二甲基丙烯酰氧基乙酯和通式（I）的碳酸酯的可交联组合物（C），其中R2表示（CH 2）m，其中m和n是整数，使得当m = 2且R 1表示CH 3时，2≤n≤6,1或n = 6和n等于1。通式（I）的碳酸酯是高度光敏的，这允许比迄今使用的单（甲基）丙烯酸稀释剂显着缩短的照射时间，或者使得在不存在光引发剂的情况下可以进行光致交联。

摘要： A continuous-wave (CW) ultraviolet (UV) curing system for solid freeform fabrication (SFF) is provided, wherein the curing system is configured to provide an exposure of UV radiation for one or more layers of UV-curable material. One or more UV exposures may initiate curing of a curable material in the layer dispensed by a solid freeform fabrication apparatus. One approach to provide the single or multiple UV exposures is the use of one or more UV LEDs, which generate UV radiation without generating any substantial amounts of infrared (IR) radiation at the same time. This allows for the curing process to be energy efficient and also allows for the SFF system to be far less complex.
摘要翻译：提供了一种用于固体自由形成（SFF）的连续波（CW）紫外线（UV）固化系统，其中固化系统被配置成为一层或多层UV可固化材料提供紫外线辐射。一个或多个UV曝光可以引发在固体自由形成制造装置分配的层中固化可固化材料。提供单次或多次UV曝光的一种方法是使用一个或多个UV LED，其同时产生UV辐射而不产生任何大量的红外（IR）辐射。这使得固化过程能够节能并且还允许SFF系统复杂得多。

摘要： The invention relates to a method producing parts using laser sintering wherein a fusible powder is exposed to a plurality of laser scans at controlled energy levels and for time periods to melt and densify the powder and in the substantial absence of particle bonding outside the fusion boundary. Strength is improved up to 100% compared to previous methods. An example includes a relatively high energy initial scan to melt the powder followed by lower energy scans controlled to densify the melt and separated in time to dissipate heat to the surrounding part cake. The rate and extent to which the powder particles are fused together can be controlled so that each successive scan can be used to fuse the particles together in discreet incremental steps. As a result, the final dimensions of the part and its density and mechanical properties can be improved compared to conventional methods and part growth avoided.
