The authors illustrate material analysis of suitable 3D-printable materials that can be used to manufacture THz components and investigate and provide solutions to challenges occurring during the 3D printing process. Samples in this study are 3D-printed using fused filament fabrication (FFF) based 3D-printers Ultimaker S5 and Bambu Lab X1E.\r\nWe investigate a total of six materials:  High Impact Polystyrene (HIPS), High Density Polyethylene (HDPE), Cyclic Olefin Copolymer (TOPAS), Polypropylene (PP), Polycarbonate (PC) and Polytetrafluoroethylene (PTFE/ Teflon). We observed that the Teflon material contains PC as material dopant to reduce the melting temperature. The authors observed warping of the 3D-structure due to the poor adhesion of material on the print-bed. An adhesive fluid or adhesive sheet applied on the print-bed before 3D-printing provides proper adhesion. Air gaps formed between the adjacent layers during the 3D-printing results into incorrect evaluations. The 3D-printing setting of material flow ratio above 100% ensures the filling of air gaps created due to layer-by-layer manufacturing. Moreover, the direction of nozzle movement also helps in achieving uniformity in 3D-printed sample. A minimal layer height of 100 µm for the 3D-printing of all the materials provides promising adhesion and better finish. Some materials e.g., PP, PC, TOPAS capture humidity, therefore the authors used specialized chambers to maintain low humidity during the whole 3D-printing process. Fan speed, low surrounding temperature contribute in blocking of the nozzles or premature cooling of the samples; therefore, it is necessary to maintain the temperature during 3D-printing. \r\nWe investigated these samples using THz-TDS setup to find the most suitable material for AM of THz-components. The results reveal that the absorption coefficient of TOPAS is the least (α < 0.5 per cm at 0.4 THz) among all the investigated materials. Therefore, with the help of material analysis of 3D-printable materials for manufacturing of THz-components, the authors introduce fundamental research results for the future developments in the field of 3D-printing of THz components. \r\n\r\n[1] A.

This article discusses the additive manufacturing and post-processing of axicons and their performance evaluation using attenuation and near-field-measurements based fundamental techniques. The axicons are manufactured using the materials cyclic olefin copolymer (TOPAS) and polymethyl methacrylate (PMMA), for their respective use in terahertz and near-infrared applications. The optical and terahertz components manufactured using traditional 3D-printing processes, e.g., fused filament fabrication or stereolithography apparatus exhibit high surface roughness in the range of 15 ± 2.5 µm, resulting in undesired propagation and scattering in the near infrared wavelengths. This research work proposes an economical post-processing technique for additively manufactured terahertz and near-infrared axicons for applications in multispectral characterization, e.g., bio-sensing. The authors used an enhanced method of dip-coating, which involves interval dipping and intermittent hardening to achieve better surface finish. An emphasis is placed on interval dipping and intermittent hardening, which lead to excellent transparency in case of additively-manufactured near-infrared axicons. The dip-coated samples exhibit surface roughness below 10 nm. With the use of heated resin material as the coating layer, due to reduced viscosity, the resin material distributes uniformly over the surface of the 3D-printed terahertz and near-infrared axicons. The authors also observed that the DOF length deviation between unprocessed and enhanced dip-coated axicons remains within the measurement error estimation from analytical calculations. In addition to the improved surface finish and transparency, the coatings are also closely matched in refractive index to the axicon material. Such post-processed axicons pave the way for producing a wide array of systems in the fields of communication, imaging, and bio-sensing."}],"publisher":"MDPI AG","date_updated":"2026-03-12T07:12:29Z","publication":"Photonics","status":"public","department":[{"_id":"DEP5020"},{"_id":"DEP6020"}],"intvolume":"        13","place":"Basel","user_id":"83781","issue":"3","title":"Multispectral Characterization of Additively Manufactured and Dip-Coated Axicons","citation":{"van":"Shrotri AN, Starsaja A, Joshi S, Preu S, Stübbe O.

However, additively manufactured components usually have rough surfaces that need post-processing, particularly for optical components, where the surface roughness must be a small fraction of the wavelength. We demonstrate an innovative and economical approach by dip-coating with the same resin used for printing in a simple post-processing step, providing high transparency to the 3D-printed optical components and reducing surface roughness while achieving perfect index matching of the coating layer. The surface roughness of the 3D-printed optical components drops to 5 nm (arithmetic average) after the dip-coating process. We observed significant performance enhancements after comparing the unprocessed optical components and the dip-coated optical components, including optical transparency and a shiny surface finish for previously rough surfaces.","lang":"eng"}],"issue":"2","title":"Achieving Transparency and Minimizing Losses of Rough Additively Manufactured Optical Components by a Dip-Coating Surface Finish","doi":"10.3390/coatings15020210","citation":{"din1505-2-1":"<span style=\"font-variant:small-caps;\">Shrotri, Abhijeet Narendra</span> ; <span style=\"font-variant:small-caps;\">Preu, Sascha</span> ; <span style=\"font-variant:small-caps;\">Stübbe, Oliver</span>: Achieving Transparency and Minimizing Losses of Rough Additively Manufactured Optical Components by a Dip-Coating Surface Finish.

However, additively manufactured components usually have rough surfaces which need post-processing, in particular for optical components where the surface roughness must be a small fraction of the wavelength. We demonstrate an innovative and economical approach by dip-coating with the same\r\nresin as used for printing, providing high transparency of the 3D-printed optical components and reduced surface roughness with perfect index matching of the coating layer in a simple post processing step. The surface roughness of the 3D-printed optical components drops to 5 nm (arithmetic average) after the dip-coating process. We observed significant performance enhancement after comparing the unprocessed optical components and dip-coated optical components, including achieving optical transparency and shiny surface finish of previously rough surfaces.","lang":"eng"}],"author":[{"last_name":"Shrotri","orcid":"0000-0003-2116-156X","id":"74090","full_name":"Shrotri, Abhijeet Narendra","first_name":"Abhijeet Narendra"},{"last_name":"Preu","first_name":"Sascha","full_name":"Preu, Sascha"},{"last_name":"Stübbe","first_name":"Oliver","id":"51864","orcid":"0000-0001-7293-6893","full_name":"Stübbe, Oliver"}],"date_created":"2025-06-30T07:39:43Z","keyword":["additive manufacturing","post-processing","optics","dip-coating"],"publication_status":"published","year":"2025","language":[{"iso":"eng"}],"_id":"13029","type":"preprint","doi":"10.20944/preprints202501.1899.v1","citation":{"apa":"Shrotri, A.

It is widely used to fabricate cost-efficient prototypes and portrays as a bridging technology to connect different scientific and industrial fields, e.g. Engineering, Medicine, etc. Consequently, additive manufacturing finds its applications in the production of patient-specific orthoses. This paper discusses the application of the stereolithography apparatus process to develop a pressure sensor based on an optical waveguide principle to embed into a below-knee orthosis. For Orthopaedic patients, the below-knee orthosis must be adjusted to the lower leg at regular intervals due to anthropometric changes in patient’s body to achieve proper mobility and correct load. Currently, this alteration relies on the patient’s estimation of support load and is only sub-optimal. Hence, the concept of developing an intelligent orthosis with a novel embedded optical system to monitor the exact support load at the neuralgic is proposed.

Moreover, it portrays as a bridging technology to connect different scientific and industrial fields, e.g. Engineering, Medicine, etc. Consequently, additive manufacturing finds its applications in the production of patient-specific orthoses. This paper discusses the development of a pressure sensor based on an optical waveguide principle manufactured using stereolithography apparatus process to embed into a below-knee orthosis. For Orthopedic patients, the below-knee orthosis must be adjusted to the lower leg at regular intervals due to anthropometric changes in patient’s body to achieve proper mobility and correct load. Currently, this alteration relies on the patient’s estimation of support load which is only sub-optimal. Hence, the concept of developing an intelligent orthosis with a novel embedded optical system to monitor the exact support load at the neuralgic is proposed.","lang":"eng"}],"publisher":"SPIE","date_updated":"2024-07-17T13:02:26Z","publication":"3D Printed Optics and Additive Photonic Manufacturing IV","status":"public","intvolume":"     12995","department":[{"_id":"DEP5020"},{"_id":"DEP6020"}],"place":"Bellingham, Washington, USA","user_id":"83781","conference":{"end_date":"2024-04-09","start_date":"2024-04-08","name":"3D Printed Optics and Additive Photonic Manufacturing IV","location":"Strasbourg"},"series_title":"Proceedings of SPIE","title":"Manufacturing of solid core optical waveguide based pressure sensor for 3D-printed below-knee orthosis","citation":{"bjps":"<b>Shahane AM <i>et al.</i></b> (2024) <i>Manufacturing of Solid Core Optical Waveguide Based Pressure Sensor for 3D-Printed below-Knee Orthosis</i>, von Freymann G, Herkommer AM and Flury M (eds).

RPP has considerably increased the rate of production and the possibility of manufacturing prototypes in the fields of electrical, optical, and mechanical engineering. The manufacturing of optical prototypes including spherical, aspheric, and special kinds of lenses and lens arrays has reformed the fabrication of optical components. In this paper, specifically designed lens array prototypes for application in visible light communication (VLC) are introduced. These lens array prototypes are manufactured using the stereolithography apparatus (SLA) process. These lens arrays are designed to achieve optimal transmission of the light beam for VLC systems. One of the prototypes from the lens arrays contains primarily four spherical lenses and one thicker convex lens and the other contains one fresnel lens as a substitute for thicker convex lens. These lens arrays are further post-processed to achieve the required transparency. These lens array prototypes are tested using laser and LEDs. The ON-OFF keying modulated light beam was transmitted through the lens array at the sender side and focused on the photo-receiver using another lens array at the receiver side which is 200 cm apart. After evaluating these lens prototypes, it can be concluded that with appropriate post-processing and high-resolution stereolithography based manufacturing, a low data rate VLC link can be formed."}],"publisher":"Society of Photo-Optical Instrumentation Engineers","publication":"Laser 3D Manufacturing VIII","date_updated":"2024-04-19T11:54:33Z","main_file_link":[{"url":"https://doi.org/10.1117/12.2586907"}],"year":"2021","language":[{"iso":"eng"}],"author":[{"first_name":"Abhijeet Narendra","id":"74090","full_name":"Shrotri, Abhijeet Narendra","orcid":"0000-0003-2116-156X","last_name":"Shrotri"},{"first_name":"Micha","full_name":"Beyer, Micha","id":"71403","last_name":"Beyer"},{"full_name":"Schneider, Daniel Johann","id":"71057","first_name":"Daniel Johann","last_name":"Schneider"},{"last_name":"Stübbe","full_name":"Stübbe, Oliver","id":"51864","orcid":"https://orcid.org/0000-0001-7293-6893","first_name":"Oliver"}],"date_created":"2022-04-19T10:20:55Z","volume":11677,"keyword":["Additive manufacturing","3D printing","Stereolithography apparatus","Spherical lenses","Fresnel lenses","Visible light communication"],"publication_status":"published"},{"type":"scientific_journal_article","_id":"7671","issue":"11","title":"Impact of industrial environments on visible light communication","citation":{"havard":"D.

However, a variety of physical effects may influence the communication quality in this potentially harsh environment: Dust and other particles lead to increased attenuation. Artificial light sources and industrial processes, such as grinding and welding, cause optical cross-talk. A multitude of reflective surfaces can lead to fading due to multi-path propagation. These three aspects are experimentally investigated in exemplary manufacturing processes at five different production sites in order to estimate the relative importance and their specific impact on VLC transmission in industrial areas. Spectral measurements demonstrate the presence of interfering light sources, which occupy broad parts of the visible spectrum. They give rise to flickering noise, which comprises a set of frequencies in the electrical domain. The impact of these effects on the communication is analysed with reference to the maximum achievable channel capacity and data rate approximation based on on-off keying is deduced. It is found that cross-talk by environmental and artificial light sources is one of the strongest effects, which influences the optical, but also the electrical spectrum. It is also observed that industrial areas differ strongly and must be categorised according to the manufacturing processes, which can induce quite a variation of dust and attenuation accordingly.","lang":"eng"}],"author":[{"last_name":"Schneider","id":"82849","full_name":"Schneider, Daniel","first_name":"Daniel"},{"id":"74090","orcid":"0000-0003-2116-156X","full_name":"Shrotri, Abhijeet Narendra","first_name":"Abhijeet Narendra","last_name":"Shrotri"},{"first_name":"Holger","full_name":"Flatt, Holger","id":"58494","last_name":"Flatt"},{"first_name":"Oliver","full_name":"Stübbe, Oliver","id":"51864","orcid":"https://orcid.org/0000-0001-7293-6893","last_name":"Stübbe"},{"last_name":"Wolff","first_name":"Alexander","id":"83362","full_name":"Wolff, Alexander"},{"full_name":"Lachmayer, Roland","first_name":"Roland","last_name":"Lachmayer"},{"last_name":"Bunge","full_name":"Bunge, Christian-Alexander","first_name":"Christian-Alexander"}],"date_created":"2022-04-19T10:21:43Z","publication_status":"published","volume":29,"year":"2021","main_file_link":[{"url":"https://opg.optica.org/oe/fulltext.cfm?uri=oe-29-11-16087&id=450941","open_access":"1"}],"language":[{"iso":"eng"}]},{"date_updated":"2024-04-19T12:53:36Z","publication":"Integrated Optics: Design, Devices, Systems and Applications VI","publisher":"SPIE","abstract":[{"lang":"eng","text":"Visible light communication (VLC) allows the dual use of lighting and wireless communication systems by\r\nmodulation of illumination devices.

Radio-frequency technologies are still predominant, but optical wireless communication (OWC) provides many advantages to fulfill the requirements of communication in industrial applications. A survey with industrial users consolidate a list with the most important demands for wireless communication within the field: The results reveal that the current heterogeneous requirements for wireless communication are valid, but highlight the need for license-free, robust and energy efficient wireless communication at rather moderate data rates. These requirements can be met by OWC, but its direct application in industrial environments is often hindered by the harsh conditions, with measurements inter alia indicating specific cross talk by light-emitting processes. In this article, these aspects are discussed one by one in order to obtain a clear perspective about the applicability, the main limitations and potential technologies for OWC and competing approaches in industrial areas. In summary, the application requirements of industrial communication are substantiated, whereas specific limitations and needs for advancement of current OWC systems are derived."}],"publisher":"Verband der Elektrotechnik Elektronik Informationstechnik e.V.","publication":"VDE-ITG Photonische Netze","date_updated":"2024-04-19T12:01:08Z"},{"citation":{"havard":"A.N.
