This receives the 3D CAD data for producing the com- ponents in the form of STL files, processes it automatically through slicing, and pro- duction can start. [...] Answer: The training requirements are negligible: all the operator needs to do is read in the STL files from a 3D CAD model and define the material. The basic knowl- edge can be learned in as little as one or two days. [...] I have an old tech- nical drawing of a factory plate, which I would like to make for a 7¼ inch gauge model. Can this be done with additive manufacturing? Answer: First of all, the drawing would have to be converted into 3D data.
CAD is used throughout the business from design to planning through to production. [...] Camo also has state of the art equipment in the design sector too: 3D product develop- ment using Pro/Engineer CAD/CAM software, data processing for stereolithography and rheological calculation, 2D mould design, NC milling program production to drawings or data transmission and integration of data from other CAD systems for production are the key words here. [...] It all started with an ALLROUNDER D Development in the firm of Camo has thus been good. A long road that started with an ALLROUNDER 320 D 850-210, which ARBURG and Camo have trodden together over the years.
When it comes to the development of new products directly from 3D CAD data, changes in design can be implemented immediately, so that the next generation of the prototype or design sample, or an ongoing product can be quickly produced ongoing product can be quickly produced without requiring a mould. igus provides a 3D printing serviceigus provides a 3D printing service This is the ideal way to test a new This is the ideal way to test a new product in practice before it is moulded in product in practice before it is moulded in large quantities. [...] Since spring 2015, igus has taken things one step further and has taken things one step further and now offers its own 3D printing sernow offers its own 3D printing ser- vice. “The customer simply uploads vice. “The customer simply uploads his 3D CAD data to our website. his 3D CAD data to our website.

With the freeformer, you can now produce one-off parts and small-volume batches - also from standard granulates, but directly from 3D CAD files, without a mould, using the additive build-up of layers. [...] This process enables fully functional three-dimension- al parts to be produced directly from 3D CAD files by applying plastic droplets lay- er-by-layer, without requiring a mould. [...] Its control system, which has been developed in-house, generates the necessary parameters from the 3D CAD to start immediately. Initially, AKF follows the proven injection moulding processes.
Enjoy reading this issue. PRINTING INFORMATION 3 Just like Christmas or East- er, Fakuma in Friedrich- shafen has now earned its place in the calendar. [...] Certifi cation enables us to document the fact that our quali- ty assurance schemes are being im- plemented and are taking effect in all departments.“ Continual means, for instance, that even mould construction from stock works on an ISO basis; that moulds for routine maintenance work are always supplied along with the last shot; that designs are based on the very latest 3D technol- ogy with PRO ENGINEER software; or that data exchange with the cus- tomer can also take place via e-mail and ISDN. [...] The communications structure for ARBURG II had to be planned and installed, browser-based ap- plications are to replace the cen- tral program structure. The two-di- mensional CAD system CADAM is currently being replaced by CAT- IA, with its real 3D design poten- tial.
Globale Konzepte müssen dezentral, d.h. national greifen, um den einzelnen Kunden optimal zu erreichen und individuell zufrie- denzustellen. [...] In der Entwicklungsarbeit setzt ARBURG voll auf CAD. Über 100 CAD-Arbeitsplätze sind in das Teile- und Stück- listensystem des Betriebs in- tegriert, zu technischer Doku- mentation und NC-Program- mierung existieren feste Verbindungen. [...] Vollständige Kontrolle über die Selogica Neun der 12 Allrounder sind mit ARBURG 3-Achs- NC-Handlings ausgerüstet, deren Programmierung voll- ständig in die Maschinen- steuerung integriert ist.
The company makes available its experience in the construction of several thousand moulds, day-to-day moulded part production, including in the multi-component and cavity sec- tor, 2D and 3D computer-aided design and the actual production of prototype moulds for new series. [...] IP-SERVE® brings together the logical use of the very latest planning, develop- ment and design tools (material databases, 3D CAD, Moldflow, Rapid Prototyping), the use of various methods of error preven- tion (parameter design, etc.) and the ”traditional” elimination of existing defects by detailed opti- misation. [...] In addition, starting from a common base, different models can be coordinated for a wide variety of intervention alter- natives.
With this application, functional one-off parts or small-volume batches can be produced from standard granulates, without a mould, using 3-D CAD files. Furthermore, we will be exhibiting sophis- ticated applications covering a variety of material combinations as well as the pro- duction of complex geometries without the need for support-structures by means of a 5-axis component carrier.” [...] Together with an expert team, he optimises the innova- tive freeformer, which builds up the com- ponents droplet-by-droplet with melt- ed standard granulate without a mould from 3-D CAD files using the ARBURG Plastic Freeforming (AKF) process (see to- day 53, p. 7 ff) to produce one-off parts or small-volume batches. [...] A com- pression-free screw with a low L/D ra- tio and low injection pressures are used. The non-return valve has been adopted from LSR processing, but has been further modified in order to precisely meet the material property requirements.
New developments are being implemented with regard to the 3D CAD process and 134 patents evidence the in- tensity of the research and development activities. [...] The ARBURG experts developed a special cylinder based on a proven model, which feeds and homog- enises the PMMA to be processed in an ideal manner. [...] OBE focuses on three business seg- ments: metal injection moulding (MIM), precision mechanical spectacle compo- nents and industrial 3D image process- ing (surface inspection). The MIM sector now accounts for around one third of overall turnover.
The ma- chines cover a clamping force range from 250 to 3,000 kN. Exclusively bolt protec- tion caps, in every conceivable shape and size, are produced on these ARBURG ma- chines.
