MCOR Weeding: The Answer to Your Finishing Woes


3D printing has revolutionized designers’ and innovators’ ability to create. Turning dreams from an idea into a tangible reality has never been easier. As computer aided drafting and engineering software becomes more intuitive and the cost of 3D printing technology improves (becoming less expensive), this revolutionary tool will also become more ubiquitous in design studios, classrooms, and production labs.



Right now, the 3D printing process is relatively straightforward: design an engineering plan for your part; translate your design into printable data; and go. The one hang up that can delay the journey from idea to reality is the finishing process. After a traditional nylon or composite part is printed, it may need to be cured with harmful (and sometimes toxic chemicals), polished, sanded, trimmed, painted, reworked, dyed, and fine-tuned. This process can take anywhere from hours to days depending on the complexity of the project and the level of perfection the designer hopes to achieve.



But don’t worry; we’ve got a solution in mind. MCOR Technologies’ 3D paper printers are true game changers: faster printing, cheaper production materials, and recyclable waste to name a few. If you’re totally new to the idea of 3D paper printing, you can find an overview of MCOR’s printing capabilities here. In our minds, one of the most major benefits of 3D paper printing is the finishing process … or lack thereof.

The finishing process for MCOR 3D paper printers is condensed into one simple step called weeding. To create a part, paper printers use selective adhesion to apply binding agents only where your part needs it. Less adhesive (or no adhesive) is applied around the project peripheral, while a razor makes small scoring marks along the excess paper supports allowing you to simply peel off excess paper around the finished product.

The act of peeling away this excess paper is called weeding. More importantly, the only tools you need are your fingers and a pair of pliers, tweezers or dental pick. No chemicals. No sanders. Nothing. If you print using the revolutionary MCOR Iris 3D color paper printer, your project will also print in full, photo-realistic colors so you can skip the painting and dying as well.

Weeding only takes a few minutes to reveal your finished, ready-to-use part. It also eliminates the need for specialized craftsmanship skills or design capabilities to complete a project. This streamlines the 3D printing process making prototyping more efficient and cost effective.

In one simple invention – 3D paper printers – MCOR has helped mitigate one of the major blockers that slow down 3D printing innovation. We’ll take weeding over a day dipping parts in harmful chemicals any day.
