If you have been working with PLA and want something stronger but don't want the nasty toxic smell of ABS, then PETG is the filament you. You will need to do a little temperature adjustments and some adjustments on flow rates to get your prints where you want them. The extra little time you will spend setting up your prints will be well worth it. Great vibrant colors and incredible strength. This filament is just plain fun and will surprise you at the quality of the parts that you will get from your prints.
