Instructions for Use "IFU"

These generic guidelines can be used for our durable 3D resins, with the exception of special resin systems, such as our water soluble sacrificial 3D resins for printing sacrificial molds and other high tech applications, which need specific and more detailed protocols and instructions for use:

1. Printing

Most of our 3Dresyns are photopolymer or light-curing resins which have been designed for SLA, DLP, LCD and Inkjet printers working with lights from 200 to 420 nm and higher upon request, including wavelengths at 385 and 405 nm. 

3D printing guidelines are available for selecting in just few easy steps the optimum printing settings

    2. Processing

    General Information

    The final physical and mechanical properties of any 3D printed material depend, among other things, on the printer specifications and printing settings, such as wavelength, power, exposure time, cleansing protocol (chemicals used for cleansing, time and temperature used during cleaning, etc) and  light post-processing or curing (wavelength, power, postcuring time, temperature, etc).  

    Our services vary from basic online support services where your technical questions will be answered directly related to fine tuning, optimisation of printing settings, postcuring and cleansing process to a more in depth consulting service where detailed recommendations of the right 3D Printing System will be provided for your specific needs and goals. Our services can include recommendations of all the required instrumentation: 3D printer with radiometry, light power and temperature control, washing and postcurintg units and all the basic tools and training for start printing professionally straight away.

    3D print cleaning process: Cleaning 3D prints

    Our Cleaning Fluid Bio is ideal for removing any uncured 3D resin from the surface of the prints. It is biocompatible, safe, non flammable and does not cause the lost of the smell sense nor attacks nor damages the mechanical properties not causes cracking nor fragility to 3d printed parts as isopropanol or ethanol.

    3D prints can be rinsed in our Cleaning Fluid Bio for cleaning them without the any of the mentioned hassles related to isopropanol and ethanol. An ultrasonic bath can be used for cleaning parts in our Cleaning Fluid Bio. If isopropanol is used be careful and minimise the cleaning time to <1-2 minutes to avoid damaging the printed parts since isopropanol tend to decrease the mechanical properties of most plastic materials.     

    Light post-curing of printed parts

    Light post-curing of the cleaned prints can be done directly in a light box or by dipping them in a clear glass or plastic container filled with our Cleaning Fluid Bio to increase their surface cure (expensive light boxes using Nitrogen gas are not needed). A long light postcuring of 30-60 minutes is recommended for ensuring that the printed material is safe and cured to its maximum degree.

    Important notes:

    Low power printers may leave printed parts too soft and tender on their surface, being prone to suffer from whitening or haziness by solvent attack (isopropanol or ethanol).

    When this happens the following alternative washing or cleaning process can be used to avoid the whitening of prints:

    IFU for 100% clarity & transparency (without any haziness or whitish finishing) 

    • print  in any SLA, DLP and/or LCD printer following our printing instructions, which can be sent upon request after ordering by email: 
    • after printing cut the supports and eliminate the uncured resin by gravity from the surface of the printed parts in the upside down position in a thermal oven heated at 60ºC for 30 minutes
    • postcure the dry prints in a normal light box for 30 minutes (optimum: 60 minutes for maximum polymer conversion and biocompatibility). If prints become yellow reduce the postcuring time and if possible the light power of the light box (or distance from the light source)
    • clean parts by dipping in our Cleaning Fluid Bio and/or combined with isopropanol at 50/50. Optionally, an ultrasonic bath can be used for speeding up the cleaning process (reduce time to <1-2 minutes). Alternatively, it is possible to spray the Cleaning Fluid Bio and/or isopropanol (or a mixture of both at 50/50) using a spray bottle to ensure that clean fluid (not contaminated with uncured resin) is always used and for reducing the contact time of isopropanol with the printed parts to avoid their damage and reduction of mechanical properties 
    • Isopropanol has the advantage of its evaporation vs Cleaning Fluid Bio which does not evaporate, requiring a clean cloth for fully drying the cleaned parts
    • Cleaning Fluid bio has the advantage of not attacking the printed parts, besides being non volatile, non flammable and odorless, not causing the lose of the sense of smell as isopropanol does.

      Chemical post-curing and cleansing can be done with our Cure tester and Purification kit (optional, ideal for ultra safe biocompatible systems)
