3D Printing a transparent plastic object....

Click For Summary

Discussion Overview

The discussion centers around the challenges and possibilities of 3D printing transparent plastic objects, exploring material options and printing techniques. It includes inquiries about the capabilities of affordable 3D printers and the suitability of various materials for specific applications.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested, Homework-related

Main Points Raised

  • One participant questions whether true transparency can be achieved with 3D printing, suggesting that translucency may be the best attainable quality.
  • Another participant asserts that FDM (Fused Deposition Modeling) parts cannot achieve clarity due to the nature of the printing process, which diffuses light.
  • A different participant mentions that SLA (Stereolithography) processes can produce clear parts, citing personal experience with a specific material that requires post-processing for optimal clarity.
  • The original poster expresses interest in flexible materials suitable for 3D printing, specifically asking for recommendations for polymers that are soft and rubbery, similar to shoe soles.
  • One response advises that not all 3D printers support all materials and suggests that finding a suitable system is necessary for achieving desired mechanical properties.
  • A later reply clarifies that the original poster does not require clarity in the material but is looking for a rubbery polymer that is less stiff than PLA or ABS.

Areas of Agreement / Disagreement

Participants express differing views on the capabilities of 3D printing technologies regarding transparency and flexibility, with no consensus reached on the best materials or methods for achieving specific properties.

Contextual Notes

Participants note limitations in material compatibility with different types of printers and the potential need for post-processing to achieve desired clarity in SLA prints.

Hello Forum,

I am new to 3D printing and wondering if any of you have been able to print transparent plastic object with 3D printing. It seems that translucency is the best that we can get. Is that true?

Are today's affordable 3D printer still only work with PLA and ABS or are there other more interesting materials
to work with?

Thanks.

Yes. FDM parts can never be flat so light will always be defused. There are post processing techniques that help:

Stereolithography (SLA) processes do have some clear options. I've gotten some parts printed by a vendor using 3DSystems Visijet SL Clear material, and they came out very clear. See here: https://www.3dsystems.com/materials/visijetr-sl-clear. Getting parts very clear does sometimes require mild polishing after printing though, it depends some on the geometry and where support material is needed.

Thank you.
SLA seems to achieve pretty good clarity. I think there are some affordable SLA printers too out there...

Two more questions if I may:

I would like to 3D print using a material that is soft, flexible and resistant, like the rubber that makes shoes sole. What polymer would you advice using? Would any type of 3D printer work with such material?

Thanks!
 
I recommend a simple internet search. Not all machines support all materials, you'll have to find a system which meets your needs both in materials and mechanical properties. If I had to guess I'd say you won't find a material which is clear and flexible, it will be one or the other.
 
Hi,

Sorry I was not clear. I don't need the clarity in this case, just a polymer that is rubbery, like a running shoe sole, and not as stiff as PLA or ABS...I will do some internet search...
