Dimifix Put in order for Dimifix and was refunded next day. Called Jonah and he said I had put in an invalid phone number. So I went back and entered another "valid" phone number and the order went through. I have used Dimifix for printing ABS and it worked great. No more lifting off the bed. Thanks for the great service Jonah.

Excellent customer support Hannah was extremely helpful and responsive when I had a question. Their customer service is top-notch and not outsourced overseas, so you talk to someone who knows exactly what is going on. This kind of service is extremely rare nowadays, and it is a breath of fresh air.
