3D resins for direct printing of Orthodontic Aligners

Discover our SLA, DLP & LCD 3D "bioplastics" 3D resins for direct printing of aligners. They are bio-based and contain over 30-40% of renewable bio-based ingredients.

Our 3Dresyns for printing aligners are made of bioplastics and are more ecological and biodegradable than the existing materials used for making aligners, which use non biodegradable petroleum based plastics.

A bioplastic is a substance made from organic biomass sources, unlike conventional plastics which are made from petroleum, as the ones used for making traditional aligners.

Direct printing of aligners is more environmentally friendly than the traditional thermo vacuum forming of disks with dental models used extensively in the market today, since it creates a massive non biodegradable waste of petroleum based plastics, which are needed for their production (huge waste of aligner dental models).

Aligners can be printed with our 3D resins in 1.5 hours even in low cost LCD 3D printers, with optimum clarity, mechanical properties and resolution of even 20 microns, without the need of any expensive postcuring and postprocessing equipment. 

Start printing aligners with 3Dresyn OD-Clear TF LTP - Rigid and LV version, which is ideal for printing professional aligners even at low room temperature of 15-20ºC.

Printing of orthodontic aligners with our 3Dresins in affordable SLA DLP & LCD printers:

  • ideal for direct printing of tooth movement aligners without damaging the periodontal ligament
  • based on 4D Shape Memory Polymers SMP´s, with excellent shape memory with temperature, recovering their shape upon heating
  • fast and easy printing and production of durable aligners with different thickness, in the same aligner, for optimum tooth movement control, with cost effective SLA, DLP & LCD printers
  • ready to use without tuning with fast printing speed and maximum resolution with most SLA, DLP & LCD printers
  • environmentally friendly, biodegradable 3D bio resins "bioplastics"
  • ideal to avoid printing non environmentally friendly models and the time consuming thermoforming  and cutting off of disks
  • printing at room temperature but also at medium and high printing temperature: 50ºC for improved performance: higher aligner durability
  • availability of 3 versions for printers working at relatively low, medium and high temperature:
    • 3Dresyn OD Clear TF LTP printable with affordable SLA DLP & LCD printers at low room temperature: 20-30ºC. It has incredible mechanical resistance and very low stress relaxation during its usage. If your room is below 20ºC, choose the Low Viscosity version during ordering
  • available in rigid and flexible versions for maximum control of teeth movement at different aligners thicknesses between 0.5-1.2 mm to prevent damaging the periodontal ligament
  • each version can be supplied at relatively low or high viscosity. Remember to select your 3D resin version among relatively low "LV" or high viscosity "HV:
    • HV stands for High Viscosity version for increased mechanical properties and biocompatibility but higher peeling force. HV versions are ideal for printers having heating systems for printing at >25ºC
    • LV stands for Low Viscosity version for decreased peeling force but relatively lower mechanical properties. LV versions are ideal for printers without any heating systems for printing at <25ºC
  • remember to select your fast, intermediate or slow printing speed 3D resin version
    • version F for Fast printing speed with minor yellowing
    • version I for Intermediate printing speed
    • version S-Slow for improved resolution, non yellowing and maximum biocompatibility
  • aligners printed and processed as per ours instructions do not become hazy, yellowish or whitish as most competitors´ resins. Read our Instructions or Use IFU


  • start printing aligners with 3Dresyn OD Clear TF LTP Rigid and Low Viscosity LV version since this version is the best for starters, for printing thin aligners at 0.5-0.8 mm with affordable SLA DLP & LCD printers at 15-20ºC (even without any heating system)
  • any LCD printer, even the low cost ones with prices of 100-200 Euro can be used for printing our resins with excellent resolution of c. 20 microns
  • follow our printing and postprocessing instructions IFU literally for 100% clarity & transparency (without any stickiness, haziness, yellowing or whitish finishing)
    • print aligners in any SLA, DLP and/or LCD printer following our printing instructions. Even low cost LCD printers, such as the Anycubic Mono at <200 Euro, can print aligners with 20 microns resolution
    • typical printing settings for most printers: 2-4 adhesion layers of 80 seconds, std layers of 10-15-20 seconds, z layers of 50-100 microns (optimum: use 100 microns z layers for faster printing speed of circa 90 minutes vs circa 150 minutes needed with 50 microns z layers)
    • after printing cut the supports and eliminate the uncured resin by gravity from the surface of the aligner in the upside down position in an oven heated at 55-60ºC for 15-30 minutes (ideally, at 555ºC for 15 minutes. Overheating >60ºC may cause yellowing)
    • once aligners are left for 5 minutes at room temperature, postcure them in a light box- a low cost 100 Euro light box such as the Anycubic Wash & Cure is good enough- for 30 minutes at room temperature or until stickiness is reduced. Avoid overheating and too long exposure times to avoid yellowing and ensure that the aligners are kept at T<50ºC during postcuring .
    • clean the aligners and eliminate any potential stickness with a fast rinse or dipping in IPA or by spraying IPA using a spray bottle to ensure that clean IPA is always used (contaminated or dirty IPA can cause haziness). 
    • for improved cure and safety clean the aligners in hot water at 50ºC for 30 minutes
  • if the mentioned recommendations are followed "literally", aligners with excellent mechanical and surface quality, clarity and light fastness will be successfully made in less than 3 hours!!! Unbelievable but True!!!!
